1 General

1.1 Product and functional overview

The Switch Actuator Modules SA/M 2.6.1 and SA/M 2.16.1 as well as the Electronic Switch Actuator Modules ES/M 2.230.1 and ES/M 2.24.1 are snapped into a module slot of the Room Controller Basis Device RC/A. They are used to control switched loads:

Load type Suitable module type

Lighting SA/M

Electrothermal valve drives (heating control) ES/M

Blower convectors (Fan coil units) SA/M

Signalling equipment ES/M

The Room Controller Basis Device establishes the connection to the ABB i-bus® KNX installation bus.

All the modules have two outputs each. The Switch Actuator Modules SA/M switch via relay outputs while the Electronic Switch Actuator Modules ES/M switch via noise-free, wear-resistant electronic semiconductor components.

SA/M 2.6.1 and ES/M 2.230.1 are automatically connected to the incoming supply when they are snapped into the Room Controller Basis Device. The incoming supply of the SA/M 2.16.1 and the ES/M 2.24.1 should be connected directly to the modules.

On the output side the devices feature screw terminals.

The comprehensive functionality is defined by programming the Room Controller Basis Device with the ETS. It is almost identical for all three devices.

3 Commissioning

The modules are solely intended for operation in the Room Controller Basis Device.

The description of the central basic functions of the Room Controller Basis Device can be found in the product manual of the Room Controller Basis Device RC/A.

The device functions are set via the application program of the Room Controller. Programming requires ETS. When the parameterization is called in the ETS, an additional software plug-in is started. It is used for setting the parameters as well as assigning the communication objects.

The application program is available in the ETS at ABB/Room automation, Room Controller.

3.2 Parameters

The following chapters describe the parameters of the application program using the parameter window. The parameter window features a dynamic structure, so that further parameters may be enabled depending on the parameterisation and the function.

The default values of the parameters are underlined, e.g.

Options: yes no

3.2.1 Parameter window A: General

In this parameter window, the mode of the output is set.

Note

The modules each have two outputs. However, as the functions for all outputs are identical, only the functions of output A will be described.

Operating mode of output

Options: no function Switch actuator Heating actuator Fan coil control

The function of the output is defined via this parameter.

The other parameters are dependent on the selected operating mode.

For further information see: The three operating modes, page 73


SA/M ES/M | 2CDC 514 055 D0201 21

3.3 Operating mode Switch Actuator


General settings are carried out in this parameter window, e.g. the reaction during/after bus voltage failure and the status response function.


Options: no yes (object “Status switch”)

The communication object Status switch is enabled with this parameter. It is used to indicate the current switching state on the bus.

• yes: The following parameters appear:

inverted

Options: no (0 = opened, 1 = closed) yes (0 = closed, 1=opened)

• yes: the status response communication object sends a 1 when the relay contact is opened and a 0 when the relay contact is closed. This can be useful, for example, when the output is operated as a normally closed contact, so that the telegram value 1 is received as a status response with an ON telegram.


22 2CDC 514 055 D0201 | SA/M ES/M

sending after bus voltage recovery

Options: no yes

This parameter determines whether the switching state is updated on the bus after bus voltage recovery. The update is carried out in connection with the transmission delay of the Room Controller.


Options: contact open contact closed unchanged

The output can adopt a defined state on bus voltage failure via this parameter.

• contact open: The output contact is opened with a bus voltage failure.

• contact closed: The contact is closed with a bus voltage failure.

• unchanged: The contact position remains unchanged at bus voltage failure. The output can still be operated, e.g. via push buttons that are connected to binary inputs of the same device.


Options: ON (1) OFF (0) unchanged

• ON (1): The output is switched on at bus voltage recovery.

• OFF (0): The output is switched off at bus voltage recovery.

• unchanged: The contact position remains unchanged at bus voltage recovery.

On bus voltage recovery, the output is set once the parameterized initialisation time of the Room Controller has elapsed.

Note

This setting can be overwritten by the parameters of the parameter window A: Function.


SA/M ES/M | 2CDC 514 055 D0201 23

3.3.2 Parameter window A: Function

In this parameter window, basic settings for the function of an output are carried out. Additional functions can also be enabled.

Reaction of output

Options: normally closed contact normally opened contact

This parameter determines whether the output operates as a normally closed contact or normally opened contact.

• Normally opened contact: An ON telegram closes the contact and an OFF telegram opens the contact.

• Normally closed contact: An ON telegram opens the contact and an OFF telegram closes the contact.

Enable function “time, staircase lighting, flashing“

Options: no yes

• yes: The parameter window Parameter window A: Time, page 25, is enabled.

3.3.3 Parameter window A: Time

In this parameter window, all settings for the function time are undertaken: Switching ON and OFF delay, Staircase lighting and Flashing. This communication object is visible if in Parameter window A: Function, page 23, the parameter Enable function "time, staircase lighting, flashing" has been selected with the option yes.

Explanations concerning the time functions can be found at Time functions, page 74. Please observe the Function chart, on page 83.

Time function

Options: staircase lighting function ON and OFF delay flashing

This parameter defines the type of the time function for an output.

• staircase lighting function: The value, with which the staircase lighting is switched on and off, can be parameterized. The staircase lighting time is started when the function is activated. It is switched off immediately after the staircase lighting time has been completed.

Note

The staircase lighting function can be started by sending a telegram to the communication object It can be paramterized in the parameter window A: Function by the parameter


26 2CDC 514 055 D0201 | SA/M ES/M

• ON and OFF delay: The output can be switched on or off with a delay via this function.

• flashing: The output starts to flash as soon as the parameterized value is received on the communication object Switch. The flashing period can be adjusted via the parameterized time duration for ON or OFF. The output is switched on at the start of the flashing period. When a new value is received on the communication object Switch, the flashing period will recommence. The relay state after flashing can be programmed. The communication object Status switch indicates the current relay state during flashing.

Note

The staircase lighting function can be started by sending a telegram to the communication object It can be paramterized in the parameter window A: Function by the parameter

The following parameter appears with the selection Staircase lighting function:

Duration of staircase lighting

Options: [h:min:s]

The staircase lighting time defines how long the contact is closed and how long the light remains on after an ON telegram. The staircase lighting time may extend depending on the value set in the parameter Warning before end of staircase lighting.

Extending staircase lighting by multiple operation (“pumping up”)

Options: no up to max. 1x staircase lighting time up to max. 2x staircase lighting time up to max. 3x staircase lighting time up to max. 4x staircase lighting time up to max. 5x staircase lighting time

If a further ON telegram is received during the staircase lighting time sequence, the remaining staircase lighting time can be extended by a further period. This is possible by repeated operation of the push button (“pumping up“), until the maximum programmed number of retriggering operations is reached. The maximum time can be set to 1, 2, 3, 4 or 5-fold time of the staircase lighting time.

The staircase lighting time is extended by “pumping up” to the maximum time. If some of the time has already timed out, the staircase lighting time can again be extended to the maximum time by “pumping up”. The parameterized maximum time may not however be exceeded.

• no: The receipt of a further ON telegram is ignored. The staircase lighting time continues without modification to completion.

• yes (retriggerable): The staircase lighting time is reset each time by a renewed ON telegram and starts to count again each time. This process can be repeated as often as desired using this selection.

• up to max. 2/3/4/5 x staircase lighting time: The staircase lighting time is extended by the 2/3/4/5-fold staircase lighting time with a renewed ON telegram.


SA/M ES/M | 2CDC 514 055 D0201 27

Staircase lighting can be switched off

Options: no yes

• yes: The staircase lighting is switched off prematurely by an OFF telegram.

Note

If yes is selected, the staircase lighting can also be switched off via the other communication objects, if they cause switch off: Logical connection, Preset, Light scene, Disable, Permanent ON, Forced operation.

Restart of staircase time after end of permanent ON

Options: no yes

The function of continuously ON is controlled via the Permanent ON communication object value. If the communication object receives a telegram with the value 1, the output is switched ON irrespective of the value of the communication object Switch and remains switched on until the communication object Permanent ON has the value 0.

Note

Permanent ON only switches ON and “masks” the other functions. This means that the other functions, e.g. staircase time or ”pumping up” continue to run in the background but do not initiate a reaction. After the end of permanent ON, the switching state, which would result without the permanent ON function, becomes active.

• no: The lighting switches off if permanent ON is ended.

• yes: The lighting remains on, and the staircase lighting time restarts.

Warning before end of staircase lighting

Options: no yes

Before the staircase lighting time times-out, the user can be informed of the imminent switch off of the lighting by a warning. If the warning time is not equal to 0, the staircase lighting time is extended by the warning time. The warning time is not modified by the “pumping up” action.

• no: No warning is given, the staircase light switches off immediately after the staircase lighting time elapses. If the staircase lighting is ended prematurely, e.g. by a switching telegram, no warning is given.


Warning time

Options: [h:min:s]

This parameter is visible if a warning is programmed before the staircase lighting time ends. The warning time must be entered in seconds. The staircase lighting time is extended by the warning time. The warning is triggered at the start of the warning time.

The warning time is not modified by “pumping up”.


28 2CDC 514 055 D0201 | SA/M ES/M

Warning via

Options: object quick switching OFF/ON object and switching ON/OFF

• object: The communication object Warning staircase lighting is set to the value 1 at the commencement of warning time and remains set until the warning time has elapsed. The communication object can be used, for example, to switch a warning light.

• quick switching OFF/ON: Switching the output (briefly OFF and ON again).

• object and switching ON/OFF: Both options are used together.

Duration of staircase lighting can be changed by object

Options: no yes

This parameter determines if a change of the staircase lighting time is possible via the bus.

• no: No modification of the staircase lighting time is possible via the bus.

• yes: A 2 byte Duration of staircase lighting communication object is enabled. The staircase lighting time can be changed via the bus here. The value defines the staircase lighting time in seconds. The function Staircase lightning, which has already commenced, is completed. A change of the staircase lighting time is used the next time it is accessed.

How does the staircase light behave with bus voltage failure?

The behaviour at bus voltage failure is determined by the parameter Reaction on bus voltage failure in the Parameter window A: General, page 21.

After supply voltage recovery the staircase light is

Options: switched OFF switched ON

This parameter determines the response of the staircase lighting after bus voltage or supply voltage recovery.

• switched ON: The staircase lighting time restarts with bus voltage recovery.


SA/M ES/M | 2CDC 514 055 D0201 29

The following parameters appear with the selection switching ON and OFF delay:

The output can be switched on or off with a delay via this function. Explanations for the ON and OFF delay can be found at ON and OFF delay, page 76. Also, a timing diagram and the effects of different ON and OFF telegrams in combination with ON and OFF delays can be found there.

Switch ON delay

Options: [h:min:s:ms]

Here the time is set, by which an ON telegram is delayed after switch on.

Switch OFF delay

Options: [h:min:s:ms]

Here the time is set, by which switch OFF is delayed after a switch OFF telegram.


30 2CDC 514 055 D0201 | SA/M ES/M

The following parameters appear with the selection flashing:

The output starts to flash as soon as the parameterized value is received on the communication object Switch. The flashing period can be adjusted via the parameterized time duration for ON or OFF. The output is switched on at the start of the flashing period. When a new value is received on the communication object Switch, the flashing period will recommence. The relay state after flashing can be programmed. The communication object Status switch indicates the current relay state during flashing.

Note

If the status response Status switch is active, it also indicates the current state of the relay during the flashing. With a rapid flashing rate, this can lead to a high bus load.

Flashing if object "Switching" is

Options: ON (1) OFF (0) Always flashing

This parameter sets the value of the communication object Switch, at which the output flashes.

• ON (1): Flashing starts when a telegram with the value 1 is received on the Switch communication object. A telegram with the value 0 ends flashing.

• OFF (0): Flashing starts when a telegram with the value 0 is received on the Switch communication object. A telegram with the value 1 ends flashing.

• Always flashing: A telegram with the value 1 or 0 triggers flashing. Suspension of flashing is not possible in this case.


SA/M ES/M | 2CDC 514 055 D0201 31

Time for ON

Options: [h:min:s]

This time for ON defines how long the output is switched ON during a flashing period. The smallest value is 1 second.

Time for OFF

Options: [h:min:s]

This time for OFF defines how long the output is switched OFF during a flashing period. The smallest value is 1 second.

Limited number of ON-impulses

Options: no yes

The number of flashing pulses can be limited using this parameter. This is useful to avoid unnecessary wear of the contacts caused by flashing. After the output has been switched on and off for an adjustable incidence (number of ON impulses), it will be switched off permanently.

Number of ON-impulses [1…255]

Options: 1…10…255

This parameter defines the maximum number of pulses.


32 2CDC 514 055 D0201 | SA/M ES/M

3.3.4 Parameter window A: Preset

This communication object is visible if in Parameter window A: Function, page 23, the parameter Enable function Preset has been enabled with the option yes.

Parameterized values are recalled in this parameter window, e.g. to implement light scenes.

The preset function is used to retrieve a parameterized value, e.g. in order to implement light scenes. In addition, the output value, that is currently set, can be saved as a new preset value.

There are two communication objects available for retrieving and storing presets. The parameters for the communication objects Preset 1/2.. and Preset 3 4... are identical. The communication objects Preset 1 and 2... are described in the following section by way of example.

Explanations of the function Preset can be found under Function Preset, page 79. Please observe the Function chart, on page 83.


SA/M ES/M | 2CDC 514 055 D0201 33

Object “Call presets 1 and 2”:

Reaction on preset 1 (telegr. value 0)

Options: no reaction ON (1) OFF (0) restore old value reset to parameterized value before preset 2

Preset 1 is retrieved if the communication object Call preset 1/2 receives the telegram value 0. The output can control a defined state in this case.

• no reaction: The output does not respond.

• ON (1): The output is switched on.

• OFF (2): The output is switched off.

• restore old value: Recreates the state before the last retrieval of Preset 2.

Note

With Preset 2, the lighting in a conference room is retrieved for a presentation. When the presentation is finished, the lighting is restored via Preset1 to the state it was in beforehand.

• reset to parameterized value before preset 2: Resets Preset 2 to the parameterized value. This can be advisable if the preset can be stored via the bus.

Note

With the parameterisation restore old value before preset 2 or restore parameterized value of preset 2, saving of the preset concerned has no effect. The saved value is not recalled, but rather the parameterized function is undertaken.

Reaction on preset 2 (telegr. value 1)

Options: no reaction ON (1) OFF (0)

This parameter determines the contact position that the output assumes when Preset 2 is recalled, i.e., communication object Recall Preset … receives a telegram with the value 1.

Preset can be set via the bus

Options: no yes

This parameter enables the communication object Save preset 1/2. It is thus possible to save the current contact position as a new preset value. It is used to store the current contact position as a preset value.

Telegram value 0 saves preset 1, whereas telegram value 1 saves preset 2.

If in parameter Reaction on preset 1 (telegr. value 0) the option no reaction, restore old value before preset 2 or restore parameterized value of preset 2 has been selected, no new communication object value is saved.

3.3.5 Parameter window A: Scene

This communication object is visible if in Parameter window A: Function, page 23, the parameter Enable function Scene has been enabled with the option yes.

In this parameter window, all settings for the function Scene are undertaken. In the 8-bit scene, a push button sends a scene number, which causes the actuator to trigger a defined output state.

Please observe the Function chart, on page 83.


SA/M ES/M | 2CDC 514 055 D0201 35

Assignment to scene number 1…64

Options: no assignment Scene 1 … Scene 64

With the function Scene up to a max. of 64 different scenes (1...64) can be addressed via a group address. With this group address all slaves, who are integrated into a scene, are linked via a 1 byte communication object. The following information is contained in a telegram:

• Number of the scene (1…64)

• Telegram: Call scene or Save scene.

The output can be allocated to up to 5 scenes.

Standard value

Options: ON (1) OFF (0)

Using this parameter, you can set which state the output adopts when the scene is retrieved.

By storing a scene, the user has the opportunity to modify the programmed value. After programming or after a supply voltage failure, the value that is parameterized here is restored.

Note

When a scene is retrieved - the Time functions are restarted, - the logical connections are re-evaluated.


36 2CDC 514 055 D0201 | SA/M ES/M

3.3.6 Parameter window A: Logic

This communication object is visible if in Parameter window A: Function, page 23, the parameter Enable function logic has been enabled with the option yes.

In this parameter window, all settings for the function Connection/Logic are undertaken.

The function Connection/Logic provides up to two logic objects for each output, which can be logically linked with the Switch communication object.

The logic is always re-calculated when a communication object value is received. Hereby, the communication object Logical connection 1 is first of all evaluated with the communication object Switch. The result is then liked with communication object Logical connection 2.

The parameters are identical for both logic objects. The function is described in the following section using the example of communication object Logical connection 1.

Explanation for the logical function can be found at Function Logic, page 78. Please observe the Function chart, on page 83.


SA/M ES/M | 2CDC 514 055 D0201 37

Function of object "Logical connection 1"

Function of object "Logical connection 2"

Options: inactive AND OR XOR gate function

The logic function of the communication object Logical connection is defined here. All three standard operators (AND, OR, XOR) are possible. The gate function is also available, which can block switching telegrams.

Result is inverted

Options: no yes

• no: There is no inversion.

• yes: The result of the logical connection is inverted.

Object value after bus voltage recovery


This parameter defines the value allocated to the communication object Logical connection 1 or Logical connection 2 at bus voltage recovery.

A further parameter appears if gate function is selected with the parameter Function of object "Logical connection 1":

Gate disabled, if “Logical connection …“ is


This parameter defines the value, at which the communication object disables the GATE.

Disabling of the gate means that the telegrams received on the Switch communication object are ignored. As long as the GATE is activated, the value which was sent last to the input of the GATE remains on the output. After a GATE is blocked, the value that was on the output before the block remains on the output of the GATE.

After the GATE is enabled, this value will be retained until a new value is received.

For further information see: 2Function chart, page 83

3.3.7 Parameter window A: Safety

This parameter is visible if in Parameter window A: Function, page 23, the parameter Enable cyclic monitoring of object Switch has been enabled with the option yes.

In this parameter window, all settings for the function Safety are undertaken.

The safety functions enable forced operation and the cyclical monitoring of the communication object Switch.

The forced operation sets the output to a defined state, which cannot be modified as long as the forced operation is active. Only the reaction on bus voltage failure/recovery has a higher priority.

The forced operation can take place via a 1 bit or 2 bit communication object. Using the 2 bit communication object, the output state is defined directly via the value of the communication object. At the end of the forced operation, the output always follows the state of the Switch communication object.

When using the 1-bit forced operation, the output state is fixed. The reaction at the end of the forced operation can also be parameterized.

Please observe the Function chart, on page 83.


SA/M ES/M | 2CDC 514 055 D0201 39

Enable function "forced operation"

Options: no yes, via 1-bit object yes, via 2-bit object

The forced operation function can be enabled via this parameter.

• no: The function is not enabled.

• yes, via 1-bit object: The following parameters appear:

Reaction on forced operation

Options: ON (1) OFF (0) unchanged

This parameter sets which state the output adopts during forced operation.

Reaction when forced operation ends

Options: ON (1) OFF (0) unchanged according switch object

The state of the relay at the end of the forced operation is defined using this parameter.

• ON (1): The output opens.

• OFF (0): The output closes.

• unchanged: The output remains unchanged.

• according switch object: The output follows the communication object Switch. The output can open, close, follow the communication object Switch or remain unchanged.

After bus voltage recovery the forced operation is

Options: active – OFF active – ON inactive

Using this parameter, the state of forced operation after bus voltage recovery is set.

• active – OFF: Forced operation is active and the output is closed.

• active – ON: Forced operation is active and the output is opened.

• inactive: Forced operation is inactive. The output follows the setting in the parameter window General.


40 2CDC 514 055 D0201 | SA/M ES/M

• yes, via 2-bit object: The following parameters appear:

After bus voltage recovery the forced operation is

Options: active – OFF active – ON inactive

Using this parameter, the state of forced operation after bus voltage recovery is set.

• active – OFF: Forced operation is active and the output is closed.

• active – ON: Forced operation is active and the output is opened.

• inactive: Forced operation is inactive. The output follows the setting in the parameter window General.

Enable cyclic monitoring of object “Switch”

Options: no yes

This parameter enables cyclic monitoring of the communication object Switch. If the device does not receive any telegrams via the communication object Switch for an adjustable period, the output is set to the safety position. The telegram value can be 0 or 1.

This function is useful if the sensor sends the communication object Switch cyclically on the bus. It is recommended that the monitoring period is set slightly higher than three times the transmission cycle time.


Safety state


This parameter sets the state, which the relay adopts while the safety position is active. The safety position is automatically cancelled as soon as the device again receives a telegram on the communication object Switch.

Cyclic monitoring time

Options: [h:min:s]

This parameter sets the monitoring time with which the communication object Switch is observed.


SA/M ES/M | 2CDC 514 055 D0201 41

3.3.8 Parameter window A: Threshold

This communication object is visible if in Parameter window A: Function, page 23, the parameter Enable threshold function has been enabled with the option yes.

In this parameter window, all settings for the function Threshold are undertaken.

The threshold value function enables the evaluation of a 1 byte or 2 byte communication object. As soon as the value of the communication object falls below or exceeds a threshold value, a switching operation can be triggered. Up to two independent threshold values are available in total.

Explanation for the threshold value function can be found at Function Threshold, page 82. Please observe the Function chart, on page 83.

Data type of object “Threshold value”

Options: 1 byte [0...255] 2 bytes (floating point value)

The data type of the communication object Threshold value can be defined using this parameter. It is possible to choose between a 1 byte integer value and a 2 byte floating point value.


42 2CDC 514 055 D0201 | SA/M ES/M

Threshold value 1 (0 = not used)

Threshold value 2 (0 = not used)

Options: 0…80…160…255 0...20,000...40,000...65,535

This parameter defines two threshold values. If the threshold values are not required, a 0 should be entered. The value range is dependent on the data type.

Object value on bus voltage recovery

Options: 0…255

This parameter determines the value of the communication object Threshold after bus voltage recovery.

Note

When a threshold value is exceeded - the time functions are restarted. - the logical connections are re-evaluated.

Threshold values define hysteresis

Options: no yes

This parameter defines whether the 1st and 2nd threshold values should be interpreted as hysteresis limits. The hysteresis can reduce unwanted violations of the threshold value if the input value fluctuates around one of the threshold values.

• no: The following parameters appear:

Reaction on…

Object value < lower threshold

Lower thrsh. <= object < upper thrsh.

Object value > = upper threshold

Options: no reaction OFF (0) ON (1)

These parameters are visible if the threshold values are not hysteresis limits. They define the reaction dependent on the threshold value.


Reaction on…

Falling below lower threshold

Exceeding upper threshold

Options: no reaction OFF (0) ON (1)

These parameters are visible if the threshold values are interpreted as hysteresis limits. They define the reaction of the output if the communication object value Input threshold value exceeds or falls below the upper or lower threshold. A reaction only occurs if the object value was previously smaller or larger than the lower or upper threshold value.

For further information see: Function Threshold, page 82.

No. Function Name Data type Flags

0 Switch Output A 1 bit

DPT 1.001

C, W

This communication object is used for switching of the output ON/OFF. The device receives a switch telegram via the switch object.

Normally open contact:

Telegram value 1 = switch ON 0 = switch OFF

Normally closed contact:

Telegram value 1 = switch OFF 0 = switch ON

Note

With logical connections or forced operations, a modification of the Switch communication object does not necessarily lead to a change of the contact position.

2 Permanent ON Output A 1 bit

DPT 1.001

C, W

This communication object is enabled if in parameter window A: Function, page 23, the parameter Enable time function has been selected with the option yes.

With this communication object, the output can be forcibly switched on.

If the communication object is assigned with the value 1, the output is switched on irrespective of the value of the object Switch and remains switched on, until the communication object Permanent ON has the value 0. After ending the permanent ON state, the state of the communication object Switch is used.

Permanent ON only switches ON and “masks” the other functions. This means that the other functions (e.g. staircase lighting) continue to run in the background but do not initiate a switching action. After the end of Permanent ON, the switching state which would result without the permanent ON function becomes active. The behaviour for the function staircase lighting after Permanent ON is programmable in parameter window 25, page 25.

This communication object can be used, for example, to allow the service or maintenance and cleaning personnel to initiate a permanent ON. The device receives a switch telegram via the switch object.

Permanent On becomes inactive after a download or bus voltage recovery.

Telegram value 1 = activates Permanent ON 0 = deactivates Permanent ON

3.4 Operating mode heating actuator

The function heating actuator switches an electronic relay, which is generally used to control an electro-thermal valve drive. The device is normally controlled by a room thermostat. Various types of control are possible (e.g. continuous-action control).


In this parameter window, all the general settings are undertaken, e.g. the behaviour during a supply voltage failure and the position of the valve drive at bus voltage failure and bus voltage recovery.

Connected valve type

Options: de-energised closed de-energised open

This parameter determines whether a valve should be controlled as de-energised closed or de-energised open.

• de-energised closed: If no current flows in the control circuit, the valve is closed. The valve is opened as soon as current flows in the control circuit.

• de-energisedy open: If no current flows in the control circuit, the valve is opened. The valve is closed as soon as current flows in the control circuit.


SA/M ES/M | 2CDC 514 055 D0201 51


Options: valve open valve closed

Should the supply voltage fail, the Room Controller is without function. Using this parameter, the output can be set to a defined state.

This parameter is only visible for the Switch Actuator Module SA/M. The Electronic Switch Actuator Modules ES/M 2.xx.1 always switch off on failure of the supply voltage (high-resistance).

Control signal is received as

Options: 1 bit (on-off control) 1 byte (continuous control)

The heating actuator can either be controlled via the 1 bit communication object Switch or the 1 byte communication object Control value (PWM).

• 1 bit (on-off control): The room thermostat controls the heating actuator via standard switching telegrams. An on-off control of the control value is implemented in this way. The 1 bit value can originate from pulse width modulation (PWM), which a room thermostat has calculated. During a malfunction when the control signal is not received by the room thermostat, the Switch actuator will undertake an autonomous PWM calculation. For this purpose, the SA/M uses the programmable PWM cycle time.

• 1 byte (continuous control): A value of 0…255 (corresponds to 0 %…100 %) is preset by the room thermostat. This process is also known as “continuous-action control”. At 0 %, the valve is closed, and at 100 % it is fully opened. The heating actuator controls intermediate values via pulse width modulation.

Send status response

Options: no yes (object “Status switch”)

This parameter enables the communication object Status Switch and defines its function. The communication object can have various functions depending on whether the actuator is controlled via a 1 bit or 8 bit communication object. The following table provides an overview:

1 bit (on-off-control) The communication object value is identical to the value of the communication object Switch

1 byte (continuous control) Setting “0 % = OFF, otherwise = ON”:

If the valve is fully closed, the communication object has the value 0; otherwise it has the value 1.

Setting “current status of the output”:

The communication object value corresponds to the current control of the valve. If the value is ON, the valve is open. If the value is “OFF”, the valve is closed.

Please note that this setting may result in an increased bus load!


52 2CDC 514 055 D0201 | SA/M ES/M

PWM cycle time for continuous control

Options: [min:s]

The interpulse period of the pulse width modulation for continuous-action control is set here (corresponds to tCYC under Operating mode Heating actuator, page 84).

For 2-step control (1 bit control), the pulse width modulation is only used in fault mode, during forced operation and directly after bus voltage recovery.

Position of the valve drive on bus voltage failure

Options: unchanged 0% (closed) … 100% (open)

This parameter sets how the valve drive is controlled on bus voltage failure. The programmed value is used as the PWM cycle time.

Position of the valve drive on bus voltage recovery


This parameter sets how the valve drive is controlled after bus voltage recovery until the first switching or positioning telegram is received from the room thermostat. The programmed value is used as the PWM cycle time.


SA/M ES/M | 2CDC 514 055 D0201 53


In this parameter window, basic settings for the function of an output are carried out. Additional functions can also be enabled.

Enable monitoring of the thermostat

Options: no yes

This parameter enables the cyclic monitoring function of the thermostat.

• yes: The parameter window A: Monitoring is enabled. Here the communication object Telegr. thermostat fault can be enabled for monitoring. Thus a failure of the room thermostat can be detected, the output changed to fault mode and a parameterized valve position can be set.


Options: no yes

This parameter enables the function Forced operation of the output in order to move the outputs to a specific position e.g. for inspection purposes.

• yes: The parameter window A: Forced operation and the communication object Forced operation are enabled.

Enable function "valve purge"

Options: no yes

This parameter enables the function Cyclic valve purge, which prevents deposits from forming in the valves.

• yes: The parameter window A: Valve purge for output A as well as the communication objects Trigger valve purge and Status valve purge are enabled.


54 2CDC 514 055 D0201 | SA/M ES/M

3.4.3 Parameter window A: Monitoring

In this parameter window, all settings for the function Monitoring are undertaken.

This parameter window is visible if in parameter window A: Function, page 53, the parameter Enable monitoring of the thermostat has been selected with option yes.

Cyclic monitoring time of room thermostat

Options: [d:h:min]

The telegrams of the room thermostat are transferred to the electronic actuator at specific intervals. If one or more of the consecutive telegrams are omitted, this can indicate a communications fault or a malfunction in the room thermostat. If there are no telegrams to the objects Switch or Control value (PWM) during the period defined in this parameter, the actuator switches to fault mode and triggers a safety position. The fault mode is ended as soon as a telegram is received.

Note

If this parameter window is visible, the room thermostat must send the control value cyclically; otherwise no function is possible. The monitoring time should be greater than the cyclic transmission time (recommended: factor 2).

Position of the valve drive on failure of the room thermostat


This parameter determines the safety position that is controlled by the actuator in error mode. The switch cycle time tCYC of the control is defined in the parameter PWM cycle time for continuous control.

Enable object "Fault report"

Options: no yes

Using the parameter, the communication object Telegr. Thermostat fault is enabled, which can indicate the failure of the thermostat.

• yes: The communication object Telegr. Thermostat fault is enabled.


SA/M ES/M | 2CDC 514 055 D0201 55

3.4.4 Parameter window A: Forced operation

In this parameter window, the function Forced operation can be activated and deactivated. This parameter window is visible if in parameter window A: Function, page 53, the parameter Enable function "forced operation" has been selected with the option yes.

During a forced operation, the actuator triggers a freely adjustable forced position, which can no longer be changed. This has the highest priority, i.e. it is not modified by a valve purge or safety position.

The forced operation can be activated via the communication object Forced operation = "1" and deactivated via the communication object Forced position = "0".

Valve position during forced operation


The valve position triggered by the actuator during the forced operation is determined by this parameter. The switch cycle time tCYC of the control is defined in the parameter PWM cycle time for continuous control.


56 2CDC 514 055 D0201 | SA/M ES/M

3.4.5 Parameter window A: Valve Purge

In this parameter window, all settings for the function Valve purge are undertaken.

This parameter window is visible if in 2Parameter window A: Function, page 53, the parameter Enable function "valve purge" has been selected with the option yes.

Regular purging of a heating valve can prevent deposits from forming in the valve area and restricting the valve function. This is particularly important at times when the valve position does not change very much. The valve is opened to the maximum during a valve purge. It can be triggered via the communication object Valve purge and/or automatically at adjustable intervals.

Period of valve purge

Options: [h:min]

The duration of a valve purge is set using this parameter. In this time the valve is fully opened. When the time has elapsed, the state before the purge is re-established.

Note

The opening time of the valve must be considered when entering the purge time. The characteristic curve adjustment is active for the valve purging time.

Automatic valve purge

Options: no yes

The automatic valve purge can be enabled with this parameter.

• yes: The valve is purged automatically at adjustable intervals. The following parameter appears.

Period between valve purges

Options: [d:h]

This parameter is only visible with automatic valve purge. It defines the interval between two valve purges.

3.5 Operating mode Fan coil control (blower convection unit)

The application provides the opportunity of controlling a fan coil air-conditioning device (blower convection unit).

If this operating mode is selected, this output has the master function in fan coil control. On the one hand, it controls fans speed 1 directly, while on the other hand it controls further outputs of switch actuator modules via communication objects that switch valves and other fan speeds. These outputs are parameterized as a Slave function.

3.5.1 What is a fan coil unit?

A fan coil unit consists of one or two cooling or heating circuits which are controlled via valves. The valves are controlled via the outputs of the switch actuator (ON/OFF). There is also a fan which blows on the heat exchanger. It can be controlled in stages (generally 3 speeds):

Control value (example) Fan speed Output 1 Output 2 Output 3

0...30% Speed 1 ON OFF OFF

30...60% Speed 2 OFF ON OFF

e.g. 60...100% Speed 3 OFF OFF ON

2-pipe system

With a 2-pipe system, only hot or cold water flows through the fan coil unit. The device therefore only has one heat exchanger.

4-pipe system

In a 4-pipe system, the fan coil unit has separate connections for hot and cold water. The device thus has two heat exchangers.


SA/M ES/M | 2CDC 514 055 D0201 61


In this parameter window, all general settings for fan coil control are undertaken.

Function of output when control is active

Options: master slave

Here you can set whether the output operates as a Master or Slave in fan coil control mode.

There can only be one output with the master function per fan coil unit. This controls fan speed 1. The master controls valve drives or further fan speeds via communication objects. These outputs must then be parameterized with the Slave function.

Important

Outputs with the slave function should be parameterized as such. If parameterized, e.g. as a Switch actuator, there is a danger that more than one output is closed under unfavourable conditions. The fan motor for example can be damaged as a result.

Outputs with the slave function are only controlled via the communication object Fan coil slave. The following parameters are only visible in the Master setting.


Options: no yes

• yes: The communication object Status switch is enabled. This reports back the output on the bus.


62 2CDC 514 055 D0201 | SA/M ES/M

Waiting time for switching between two speeds

Options: [s:ms]

The operating time is delayed to enable an idle period, when switching over the motor or valve, or to prevent the period that they are switched on/off from being too short. The value range can be set from 500 ms to 1 min.

Type of fan coil unit

Options: 4 pipe system 2 pipe system

This parameter defines type of fan coil unit.

• 4 pipe system: The fan coil unit has separate connections for hot or cold water. The device thus has two heat exchangers.

• 2 pipe system: Only hot or cold water flows with a fan coil unit. The device therefore only has one heat exchanger. The following parameter appears:

Operation mode

Options: heating and cooling heating only cooling only

The operating mode can be set using this parameter.

• heating and cooling: The following parameter appears:

Function of object “Toggle heating/cooling“

Options: normal (heating = 0, cooling = 1) inverted (heating = 1, cooling = 0)

This parameter determines the assignment of the telegram value. The values can be inverted. The assignment of the function to the value is determined by the thermostat.


SA/M ES/M | 2CDC 514 055 D0201 63

3.5.3 Parameter window A: Speeds

In this parameter window, the threshold values for the fan speeds are defined.

Number of fan speeds

Options: 1 speed 2 speed 3 speed 4 speed 5 speed

This parameter defines the number of fan speeds that the fan coil unit has. Speed1 to Speed5 can be set. The communication objects Speed 2 to Speed 5 are enabled accordingly.

Threshold OFF speed1

Threshold speed1 speed2

…

Threshold speed4 speed5

Options: 0% (0) … 100% (255)

These parameters become visible depending on the number of fan speeds selected. This parameter defines the thresholds of the control values from which a fan switches up or down.

Hysteresis between fan speeds in % [0…20]

Options: 0…5…20

If a fan value fluctuates around a fan speed, the ventilation would be switched on and off continually. This can be prevented by setting a hysteresis.


64 2CDC 514 055 D0201 | SA/M ES/M


In this parameter window, all further functions for fan coil control are enabled.

Enable monitoring of the thermostat

Options: no yes

Using this parameter, cyclic monitoring of the thermostat can be enabled.

• yes: The Parameter window A: Monitoring, page 65, for cyclic monitoring of the thermostat is enabled. The output switches to fault mode and moves to a defined position. The failure of the thermostat can thus be detected.

Note

For the function monitoring of the thermostat, the thermostat must be parameterized, so that the communication objects Heating and/or Cooling are sent cyclically. Permanent monitoring is not possible without cyclic sending of the values.

Enable function “fan speed limitation”

Options: no yes

• yes: The Parameter window A: Step limitation, page 67, for the fan speed limitation is enabled. This function enables, e.g. noise reduction via the bus during operation at night.


Options: no yes

• yes: The Parameter window A: Forced operation, page 68, is enabled. With forced operation of the fan speed and the valve position, the outputs are moved to a specific position, e.g. for inspection purposes.


SA/M ES/M | 2CDC 514 055 D0201 65

3.5.5 Parameter window A: Monitoring

This parameter window is visible if in parameter window A: Function, page 64, in the parameter Function monitoring of the thermostat, the option yes has been selected. The cyclic monitoring of the thermostat is implemented via the communication objects control value heating and control value cooling. As soon as the communication objects are not received for a certain period, the device switches to fault mode (communication object Fault = 1).

3.5.7 Parameter window A: Forced operation

In this parameter window, all settings for the function Forced operation are undertaken.

This parameter window is visible if in parameter window A: Function, page 64, the parameter Enable function "forced operation" has been enabled.

During a forced operation, the actuator triggers a freely adjustable forced position. This has the highest priority, i.e. it is not modified by a valve purge or safety position. The forced operation can be activated via the communication object Forced operation = ON and deactivated via Forced operation = OFF.

Fan speed during forced operation


This parameter defines which fan speed and valve position are triggered during the forced operation.

Valve position during forced positioning

Options: heating cooling unchanged

The valve position triggered by the actuator during the forced operation is determined by this parameter. The switch cycle time tCYC of the control is defined in the parameter PWM cycle time for continuous control.

4 Planning and application

4.1 The three operating modes

It is possible to choose between three operating modes for each output:

1) Switch actuator

This function is used for normal switching, e.g. of lighting. The output is controlled directly via the communication object Switch. A large number of additional functions are possible.

For further information see: Operating mode Switch actuator, page 74

2) Heating actuator

In this function, the output is used to control heating valves, e.g. in an individual room temperature control system. A room thermostat sends a control value, which the output uses to control the valve (e.g. as PWM or 2-step control).

For further information see: Operating mode Heating actuator, page 84

3) Fan coil control (blower convector)

This function is used to control a fan coil unit for air conditioning in a room, e.g. in an individual room temperature control system.

The function is as follows: An external room thermostat determines the setpoint value (0…255). The fan speed and the setpoint value of the fan coil unit are to be controlled depending on this setpoint value. Several outputs are required for control and the output therefore controls further outputs (Slaves) as a Master via the bus. The master output itself controls fan speed 1.

For further information see: Operating mode Fan coil control, page 86

4.2 Operating mode Switch actuator

4.2.1 Time functions

Different functions can be realised using the function time:

• staircase lighting function

• ON and OFF delay

• flashing

4.2.1.1 Staircase lighting function

The output switches off automatically after the staircase lighting time TON. With each telegram with value 1, the time restarts (retrigger function), if the parameter Extending staircase lighting by multiple operation ("pumping up") is set to yes in the parameter window A: Time to no, not retriggerable.

This corresponds with the basic response of the function Staircase lighting, as long as a warning is not parameterized.

SA/M ES/M | 2CDC 514 055 D0201 75

Warning

An additional warning function enables the user to be warned in good time, before the staircase lighting time elapses. It can be carried out by switching the output on/off briefly or by sending a communication object.

The warning time TWARN extends the ON phase. At the start of the warning time, the output can be briefly switched on and off, and/or the communication object Warning stair lighting can be written with a value 1. The output is switched off briefly for the period TWARN, before the staircase lighting time TON elapses and the communication object Warning stair lighting is sent. As a result, for example, half of the lighting is switched off and a LED is switched on as a warning.

The entire staircase lighting time, in which the staircase lighting is on, corresponds with the time period TON plus TWARN.

Retriggering

Via “pumping up”, that is actuation of the push button several times in succession, the user can adapt the staircase lighting to their current needs. The maximum duration of the staircase lighting time can be set in the parameters.

If the device receives a further ON telegram when the staircase lighting is switched on, the staircase lighting time is added to the remaining period.

The warning time does not change due to "Pumping up" and is added to the extended (x-fold TON) ON time.

Application examples:

• Lighting control in stairwells

• Monitoring of telegrams

4.2.1.2 ON and OFF delay

The ON and OFF delay delays switch on or switch off of the output.

The delay time TD1 or TD0 starts after a switch telegram, and after it has timed out, the output executes the switch telegram.

If a new ON telegram with the value 1 is received during the switch on delay, the time of the switch on delay starts again. The same applies to switch off for the switch off delay. If a new OFF telegram with the value 0 is received during the switch off delay, the time for the switch off delay starts again.

Note

If the device receives an OFF telegram during the switch on delay TD1, an ON telegram is disregarded.


SA/M ES/M | 2CDC 514 055 D0201 77

4.2.1.3 Flashing

The output can flash when the output is switched on and off periodically.

The switch on time (TON) and switch off time (TOFF) during flashing can be programmed.

Note

Please note that the maximum number of switching operations is limited for the Switch Actuator Module SA/M. The number of switching operations is unlimited for the Electronic Switch Actuator.

4.2.2 Function Logic

With the function Connection/Logic it is possible to connect the switching of the output with certain conditions. Two connection objects are available:

At first, the communication object Logical connection 1 is evaluated with the communication object Switch. The result is then liked with communication object Logical connection 2.

The following functions Connection/Logic are possible:

The communication object Switch is only allowed through if the GATE is open. Otherwise the receipt of the communication object Switch is ignored.

Example shown here: Disable if “0” (OFF)

The function Connection/Logic is always re-calculated when a communication object value is received.

Example

The GATE logic is programmed, so that a disable is implemented as soon as the communication object Logical connection x receives a 0. The output of the logical connection is 0. The communication object Logical connection 1 receives a 0, i.e. the GATE blocks. The communication object Switch receives 0, 1, 0, 1. The output of the logic operation always remains 0. The communication object Logical connection x receives a 1, i.e., the GATE is enabled if it is set in the parameters. The output of the logical connection is recalculated.

Application: Disable the switching of the lighting. Only switch the lighting on under certain conditions.

4.2.3 Function Preset

A parameterizable switching state can be retrieved with the help of presets. Light scenes can therefore be implemented, for example, with a 1 bit communication object.

Retrieve preset

Switch states (preset values) can be retrieved via the communication objects Recall preset 1/2. A maximum of two preset values are available for each output:

Action Telegram

Recall preset 1 Communication object Recall Preset 1/2 = 0




Store preset

The current switching state is stored as a new preset value via the object Set preset …. The user can, for example, adapt a light scene in this way. The presets are stored via the following values:

Action Telegram

Special function: Restore state

A useful special function can be assigned to Preset 1. It is possible to recreate the brightness level (states), which were present before retrieving Preset 2. The following diagram clarifies this:

This function can be used, for example, after a presentation to restore the lighting to the state it was in beforehand.

SA/M ES/M | 2CDC 514 055 D0201 81

4.2.4 Function Scene

With the 8 bit scene, the push button issues the instruction to call a scene. The scene is not stored in the push button but rather in the actuator. All actuators are addressed using the same group address. It is thus sufficient to send a single telegram to recall the scene.

A scene number is sent with the telegram value, which must correspond with the scene number in the parameters of the actuator.

After a long push button action, for example, the actuators receive a save command, which causes them to store the current value issued by the actuator as a new scene value.

Up to 64 different scenes are managed via a single group address. An 8 bit scene telegram contains the following information:

• Number of the scene (1…64)

• Store/Call scene

Benefits

The function Scene with ABB i-bus® devices offers the following decisive advantage: All settings to be undertaken in a scene are stored in the device. Therefore, they must not be sent via the KNX with a scene recall, and only a figure value, which has been assigned to this scene, is necessary. This considerably reduces the load on the bus and prevents unnecessary telegram traffic on the KNX.

4.2.5 Function Threshold

The function Threshold monitors a 1 byte or 2 byte value. As soon as this value exceeds or falls below a threshold value, the output can be switched. The threshold values can be interpreted as hysteresis values:

Threshold values are hysteresis values

When the value exceeds the upper threshold or falls below the lower threshold, the output is switched.

Threshold values are not hysteresis values

When the value exceeds or falls below any threshold value, the output is switched.

Example

If the object Threshold value receives a value, which does not exceed or fall below any of the threshold values when compared to the old value, no switching operations are triggered.

The following illustration indicates the sequence, in which the functions are processed.

Send telegram

Example

On receipt of a Logical connection object, the linking logic is evaluated first of all. The result is analysed by the time function; when the staircase lighting function is active, this can result in the staircase lighting being switched on.

The forced operation has the highest priority, as it is evaluated last of all the functions.

4.3 Operating mode Heating actuator

The Heating actuator function is normally used to control an electrothermal valve drive. The output receives its control value from a room thermostat.

The electrothermal valve drive can be triggered via two-step control or pulse width modulation. With pulse width modulation, the control is implemented by a variable mark-space ratio. The following example clarifies this:

During tON, the valve is triggered with Open (ON phase). During tOFF the valve is triggered with Close (OFF phase). Due to tON = 0.4 x TCYC, the valve is set at approx. 40 %. TCYC is the so called PWM cycle time for continuous control.

Important

Pulse width modulation leads to frequent switching of the outputs. Consider the limited number of switching cycles for standard switch actuators! The use of electronic switch actuators should be the preferred method.

4.4 Operating mode Fan coil control

4.4.1 Terms

“Fan Coil unit“ is a term used for a valve convector or blower convection unit. The Fan Coil unit is connected to a central heating and cooling water supply and generates the desired temperature for the room. A room can be heated, cooled and ventilated using a Fan Coil unit.

4.4.2 Configuration of a HVAC system with Fan Coil units

A HVAC system with Fan Coil units (HVAC = heating, ventilation, air-conditioning) consists of a central heating and cooling water system. The Fan Coil units are installed in rooms and directly connected to the heating and cooling circuit.

SA/M ES/M | 2CDC 514 055 D0201 87

4.4.3 Design of a Fan Coil unit

The heat exchanger and the fan are the most important components of a Fan Coil unit. Heating or cooling water flows in the heat exchanger depending on the desired room temperature. The flow of water through the heat exchanger is controlled via the valves.

The fan blows air past the heat exchanger and into the room through a filter. The air is heated or cooled in the heat exchangers and thus generates the desired room temperature. The fan is driven by a motor. The motor and the valves are controlled by a Fan Coil Controller FC/S 1.1.

The water condensation, which results during cooling, collects in a condensation water trough.

4.4.4 Variants

Pipe systems

A Fan Coil unit can be configured as a 2, 3 or 4-pipe system.

In the 4-pipe version, separate water circulation loops are used for hot and cold water. There are thus also two separate heat exchangers for heating and cooling, which are each triggered via a valve in the Fan Coil unit.

The 3-pipe version functions in a similar way to the 4-pipe version. In the 3-pipe version there is also a separate inlet for heating and cooling water as well as two separate heat exchangers with one valve each. In contrast to a 4 pipe version, the 3 pipe version has a common return for heating and cooling water.

The 2-pipe version consists of just a single water circuit, which is heated or cooled alternately to suit the season. In a 2 pipe Fan Coil unit there is only one heat exchanger with a valve.

In some HVAC systems, cooling is undertaken exclusively with a 2-pipe Fan Coil unit. The heating function is undertaken by a conventional heater or an electrical heater.

The figure shows the control of a Fan Coil unit (example), consisting of a fan drive (3 speed) and two valves for a cooling or heating circuit. The device is therefore a 3 or 4-pipe version.

Five switch outputs are required for control which is why three switch actuator modules are necessary. The free output can be used elsewhere.

Switch output A of the switch actuator at the top controls fan speed 1 and simultaneously adopts the function of the Master. The other outputs must be parameterized as a Slave. The master controls the slaves via the normal group address assignment.

Variations

If the Fan Coil unit only cools or heats (2-pipe-version), only one valve is required and two switch actuator modules are sufficient.

When using electrothermal valve drives for valve control, the use of Electronic Switch Actuator Modules (ES/M) is recommended.


SA/M ES/M | 2CDC 514 055 D0201 91

4.5 Reaction on voltage failure and recovery


The behaviour of the outputs at bus voltage failure can be parameterized. The function of the Room Controller is retained provided that the supply voltage (115 / 230 V AC or 12 V DC auxiliary voltage) is available.

If it has been set in the parameters, the Room Controller can thus continue to keep the functions in the room maintained even at bus voltage failure.

In the Heating actuator operating mode, any neutral position of the valve can be triggered. In the Fan coil control operating mode, the master and slave outputs are switched off (high-resistance). Fan speed 0 is thus triggered.

Example

Conventional push buttons are connected to a Room Controller via binary input modules. The Room Controller also regulates the lighting in the room. After bus voltage failure, the lighting can still be operated since the Room Controller is not supplied by the bus.


The behaviour of the outputs is programmable. In the master Fan coil control function, the outputs remain switched off until a new control value is received.


The supply voltage has failed if there is a failure of both the 115/230 V AC supply and the 12 V DC auxiliary supply. The Room Controller has no function in this case.

For the Switch Actuator Module SA/M, the status of the relay outputs can be parameterized, so that a defined state can be established. The setting is carried out in the parameter Reaction on bus voltage failure.

In the Heating actuator operating mode, it can be set whether the valve should be fully open or closed during the supply voltage failure. In the Fan coil control operating mode, the master and slave outputs are opened. Fan speed 0 is thus triggered.

For the Electronic Switch Actuator Modules ES/M, the outputs always switch off during the supply voltage failure (high-resistance).

Note

The preset and scene values that have been changed by the user are lost on failure of the supply voltage. They are overwritten by the parameterized default values.

Reaction on supply voltage recovery

The behaviour of the outputs is identical to the behaviour on bus voltage recovery. It can be parameterized for each output (except for Fan Coil control).

4.6 Behaviour after programming

After programming, the device behaves in the same way as after bus voltage recovery (parameterizable).
