7 Controller description

7.1 Controller structure

Fig. 1 Controller structure

The controller consists of a touch control

panel (1) and control module (3). Both

components are connected with a 4-signal

cable (2). An external temperature sensor

(4) connected with the module (3) with 2-

wire cable (5) is necessary for proper

operation of the system. Touch control panel

(1) can be placed in a house apartment, e.g.

in the living room or hall. Module (3) should

be placed in the boiler room close to

electrical devices included in the central

heating system. Cable (2) should meet the

requirements listed in installer’s manual.

Control panel is equipped with a room

temperature sensor and therefore it also acts

as a room thermostat. There is a possibility

of connecting many control panels measuring

room temperature for various heat

circulations.

Wire (2) should meet special

requirements listed in pt. 10.9

on page 22

7.2 Controller operation

Heat source

The controller controls the operation of heat

source, e.g. an automatic gas, oil or pellet

boiler, by activating or deactivating it

according to a heat demand of the central

heating system.

Hot utility water

The controller controls the operation of HUW

pump loading a hot water tank up to a user-

defined temperature. Preparation of HUW

can be programmed in time intervals. The

controller also controls a HUW circulating

pump. It enables quick transportation of

HUW to a bathroom or kitchen located far

away.

Heating circuits

The controller control the operation of one

direct heating circuit (radiator) and two

adjustable heating circuits (radiator or floor).

Water temperature in heating circuits is set

by weather, i.e. water temperature in the

heating circuit is calculated in accordance

with a temperature from the external sensor.

Due to this, despite of varying external

temperature, a room temperature in heated

compartments are kept on a set level.

Dependent and independent heating

circuits

- Dependent heating circuits – controller

touch panel can be a common room

thermostat for many heating circuits. For

example, room temperature readings on a

panel installed in the living room affect

operation of both radiator and floor circuit.

Both these circuits heat up a common

temperature sensor located on the screen by

supplying heat.

- Independent heating circuit – there is a

possibility of connecting many control panels

measuring room temperature independently

and affecting assigned heating circuits. It is

the way to obtain independency of heating

circuits, e.g. in case when one part of the

building is used for the whole year and the

second part is used periodically, e.g. for rent.

More details are include in pt. 10.10 on page

23.

the user with additional information

concerning any parameter in the controller

menu. In order to obtain additional

information, select the parameter and press

“i” button in a lower bar of the controller

(button no. 3 in Fig. 3 , page 10).

Information window will be displayed.

9.2 Anti - freeze

Anti – freeze function is applicable only to

active controller work modes: “off” or “auto-

eco”. In “auto-eco” mode, this function is

executed only during a night reduction.

Fig. 7 View of main menu screen with turned OFF work

mode with active anti-freeze function

When measured temperature drops below

7°C, all heating circuits become active.

Independently of this, heating circuits can be

activated by the external temperature sensor

readings.

Description of anti-freeze protection against

the external temperature sensor readings:

Direct circuit (H1 circuit, non-adjustable)

When the external temperature drops below

3°C, an anti-freeze delay time, e.g. 4h

(parameter located in service settings) must

expire. If after this time the external

temperature is still under 3°C, a direct

heating circuit pump will be activated for 30

minutes. After 30 minutes the pump will be

off. Heat source (boiler) is activated along

with the pump and it heats the water in

direct circuit up to a minimum value (service

17

parameter). Next activation of the pump will

take place after an anti-freeze delay time,

e.g. 4h, unless the external temperature

exceeds 3°C. In such case the pump will not

be activated.

Adjustable circuits (H2 circuit, H3 circuit)

After the external temperature drops below

3°C, an anti-freeze delay time, e.g. 4h

(parameter located in service settings) must

expire. After this time the external

temperature is still under 3°C, an adjustable

heating circuit pump will be activated for 15

minutes. After 15 minutes, water

temperature in the circuit will be checked. If

it is higher than 13 °C, the pump will be

stopped. If it is lower than 13 °C, the pump

will continue its operation and heating circuit

will be heated by a heat source (boiler) up to

a minimum value (service parameter). The

pump will be stopped unless the external

temperature exceeds 3°C.

Do not disconnect or leave the

controller in STAND-BY mode

without antifreeze functions

active within a freezing hazard period.

Fig. 8 View of main menu screen with turned OFF work

mode with active anti-freeze function

If heating circuits have to be off during this

period, activate “off” or “auto-eco” mode for

heating circuits and HUW tank in acc. with.

pt. 8.5 instead of turning the controller off.

Description of the anti-freeze function for

HUW tank:

After the HUW tank sensor temperature

drops below 5°C, HUW tank will be loaded up

to a minimum temperature value (service

parameter).

menu Service settings HUW circuit

settings Minimum temperature

Do not disconnect the controller

within a freezing hazard period.

9.3 Room temperature stabilization

Stability of maintaining room temperature

depends on:

- selection of weather control settings,

- selection of room thermostat settings.

Selection of weather control settings

Room temperature maintained in heated

compartments depends on a temperature of

water in heating circuit. Water temperature

in heating circuit is set depending on a

temperature outside the building. The colder

is outside, the higher heating circuit

temperature. This dependence is expressed

in the controller in a form of a heating curve.

Heating curve can be changed and it reflects

thermal characteristics of the building. The

less heated building the higher heating curve

should be. Heating curve should be selected

experimentally by changing it in several day

intervals. Detailed description concerning

how to select a heating curve and weather

control settings are given in installer’s

manual. Heating curve should be selected by

the installer.

Selection of room thermostat settings

The controller enables correction of preset

temperature of water in heating circuit in

accordance with room temperature readings.

The higher discrepancy between preset and

measured room temperature, the higher

correction of temperature of water in heating

circuit. Detailed description concerning room

thermostat settings are given in installer’s

manual.

Anti-freeze function deactivated!

9.4 Solar

he controller operates a basic solar system

which loads the HUW tank. Solar system

operation requires additional temperature

sensors. No additional module is required.

Information concerning condition of the solar

system can be found in:

menu Information Solar

or on the last screen of the display which can

be accessed by clicking an arrow on the right

side of the main screen, pt. 7.3, element no.

11.

Optimize preparation of HUW in

order to take a full advantage of

heat gains from the solar panel.

Preparation of HUW can be optimized by

appropriate programming of time program

for HUW tank. Set HUW tank work mode to

“Auto”. Define time program for HUW tank in

such way to set insolation periods as “night”.

Due to this the boiler will not heat up the

HUW tank. Similar effect can be obtained by

setting the work mode for HUW tank to “Off”

manually.

Loading HUW tank can be also optimized by

setting a lowest possible preset temperature

of HUW tank. The lower preset temperature

of HUW tank, the less often boiler will

become active in order to load the tank and

solar energy gain will be higher.

Installer from a service level should set the

highest possible HUW tank maximum

temperature. This will generate the

maximum heat gain. On the other hand there

is a risk of scalding with hot water and

exceeding temperature limit for a particular

HUW tank!

Risk of scalding with HUW! In order

to protect against scalding, install

an additional protective automatics,

e.g. thermostatic mixing valve.

During periods of very high insolation, there

can be a situation in which the HUW tank is

not able to absorb big amount of heat. In

such case, a solar pump transporting heat

from a solar panel to HUW tank becomes off.

Due to a risk of damaging the pump, it is

turned off only when the solar panel

temperature drops. In practice, the solar

system is turned on again the next day after

the sunrise. It indicates a normal operation

resulting from the fact that there is no

10 Controller assembly

Controller structure is described in pt. 7.1.

Proposed assembly procedure:

10.1 General requirements

The controller should be installed by a

qualified installer in accordance with

currently valid standards and regulations.

Prior to installing the controller make sure

that it will properly cooperate with hydraulic

and electrical system. Requirements for

electrical system are listed in pt. 12.

Hydraulic installation should generally fit to

the diagram in pt. 11. It is recommended to

install an output module inside boiler room

first. During the assembly, control panel

should be electrically connected to the output

module and left in the boiler room. In will be

used to verify if electrical connections are

proper. After verification, the control panel

can be moved to a residential room.

10.2 Output module assembly

Assemble the output module on the boiler

room wall.

Fig. 9 Output module assembly

Caution: Disconnect the

electrical supply prior to starting

the output module assembly!

In order to assemble the output module on a

wall (5), unscrew bolts (3) and remove the

cover (1). Fix the module base (2) with

screws (4) to the wall (5) through holes (6).

The controller should not be subjected to

direct solar radiation nor high temperatures

(max. 45 C). Moreover, the controller

cannot be used in conditions of vapor

condensation nor be subjected to water.

10.3 Temperature sensors assembly

Connect temperature sensors to the output

module in acc. with pt. 11 and pt. 12.1. At

least one heating circuit temperature sensor

and one external temperature sensor

(weather sensor) are necessary to activate

the controller.

Caution: the controller is

equipped with various types of

temperature sensors! Connecting

an inappropriate sensor will cause

incorrect operation of the

controller!

Table 1 Sensor types

Sensors for heating circuits

Direct heating circuit sensor (H1-S) should

be installed in a hydraulic coupling, Fig. 18

If there is no hydraulic coupling in the

system, it can be fixed to a supplying pipe

coming out of the heat source (boiler).

Assemble the adjustable heating circuit

sensor (H2-S or H3-S) on a pipe after the

heating circuit pump, as shown in Fig. 18 .

21

Insulate sensors affixed to the external

surface of the pipe with the use of thermal

insulation covering the sensor together with

the pipe.

External temperature sensors

The controller cooperates only with a CT6-P

type weather sensor. Sensor should be fixed

to a coldest wall in the building. Usually it is

a north wall under the roof. Sensor should

not be subjected to direct solar radiation nor

rain. Sensor should be fixed on a minimum

height of 2 m above the ground and in a

distance from windows, chimneys and other

heat sources which could interrupt the

temperature measurement (at least 1,5m).

Use a connecting cable with a cross section

of at least 0,5mm2 and length of 25 m.

Polarity of wires is not important. Fix the

sensor to the wall with the use of screws.

Holes containing fixing screws can be

accessed by unscrewing a sensor cover.

Fig. 10 Connecting the CT6-P external temperature

sensor

Temperature sensor can be checked acc. to

pt. 16 on page 47.

10.4 Connecting a heat source

Make electrical connections between the

controller output module and heat source,

e.g. gas boiler. Use a terminal (S-B) 19-20

as shown in Fig. 27 . Boiler contact can be

potential-free or can be energized with

voltage not exceeding 230V~.

Caution: risk of electric shock

caused by current from a heat

source. Disconnect the controller

and heat source electrical supply

and make sure there is no

dangerous voltage on terminals.

Protect yourself against

incidental generation of supply

voltage!

10.5 Connecting pumps

Make electrical connections between heating

circuit pumps and the controller in acc. with

Fig. 27 and Fig. 18 .

10.6 Connecting servos

Electrical servo is installed only when there is

an adjustable heating circuit “H2 circuit” or

“H3 circuit”, Fig. 18 .

The controller cooperates only with servos of

valves equipped with limit switches. Using

other switches is forbidden. Used servos

must be characterized with a full revolution

time of 90 to 255s.

Connecting a servo on example of H2

CIRCUIT:

Disconnect electrical supply,

connect the H2-S circuit temperature

sensor, (8) Fig. 18 ,

connect electrical cables of the adjustable

heating circuit pump in acc. with Fig. 27

make electrical connections with the

controller in acc. with Fig. 27 and

documentation of the valve servo,

read valve full opening time from a servo

housing, e.g. 140s. It is usually located

on a servo nameplate and within a range

of 90 – 180s.

Connect electrical supply and activate the

controller. Enter read time to:

menu service settings H2 CIRCUIT

pipe located after the circuit pump,

electrical connection of the servo can be

deemed as correct. In case of dropping

temperature, disconnect electrical supply

of the controller and exchange wire on

terminal no 10 with a wire on terminal

no. 12, Fig. 27 .

10.8 Control panel assembly

Move the control panel from boiler room to

residential room. Fix the panel (1) to a wall

(2) in a representative residential room, e.g.

living room or a hall 1,5m from the floor.

Fig. 11 Control panel assembly

Panel is equipped with a room measurement

function. Due to this it should be installed far

away from heat sources such as radiators or

a TV and from windows and doors which can

cool the room temperature sensor.

Connect the panel (1) with a module with the

use of cable (4) in acc. with Fig. 27 on

page 36. Caution: should meet the

requirements listed in pt. 10.9 on page 22.

Cable (4) can be built in a wall or led along

wall surface.

In service settings of each circuit assign the

control panel to an appropriate heating

circuit or a group of heating circuits for which

it will serve as a room thermostat, in acc.

with Fig. 14 and Fig. 15.

After the panel is assembled it is

recommended to change its name. This

name should correspond to a room in which

it is located, in acc. with pt. 8.11.

10.9 Panel – module cable

Cable connecting the control

panel with a module should

have 4 wires. Cross section of

wires should be at least 0,5

mm2

23

module with the panel where: 1 – control panel,

2 – output module.

In a situation when there is no possibility of

using 4-wire cable, a 2-wire cable can be

used. It requires using an additional 12V DC

adapter with output of min. 400mA, Fig. 13.

Fig. 13 Two-wire connection of an output module with

the panel where: 1 – control panel, 2 – adapter, 3 –

10.10 Connecting control panels

User can connect one or many control panels

to the controller. Each of these panels can

serve as a room thermostat for an individual

heating circuit or a group of heating circuits.

Fig. 14 shows an example with one control

panel serving as a common room thermostat

for “H2 circuit” and “H3 circuit”. In this

solution, both circuits are dependent on one

another and it is not possible to set a

different room temperature for rooms heated

by “H2 circuit” and “H3 circuit”. In this

situation, controller settings will be:

Fig. 15 shows an example with two control

panels. Panel (1) serves as room thermostat

for adjustable “H2 circuit”. Panel (4) serves

as a room thermostat for adjustable “H3

circuit”.

module.

Names of control panel and heating

circuits can be changed in acc. with

pt. 8.11

Maximum 6 control panels can be connected

to the controller. The controller can

electrically supply maximum two control

panels, Fig. 16 .

Fig. 16 Connecting three control panels, where:

1,2,4 – control panels, 3 – output module, 5 –

Each control panel should be characterized

by the unique network address. Addresses of

control panels are assigned automatically.

However, in case of problems concerning

service settings, set their addresses in order

to prevent doubling.

10.11 Heat source output

modulation

The main heat source can work with a

constant nominal power or work with output

modulation. To the power of heat sources

can be modulated, it must be equipped with

the type 0...10V and be connected to

terminals 38-39 of the regulator. Set the

correct value of the parameter:

25

∆T = preset temperature heat source –

temperature measured at sensor H1-S.

10.12 Floor control settings

Make weather control settings in order to

stabilize room temperature.

Weather control should be enabled

separately for each heating circuit in service

settings, pt. 13.1 or pt. 13.2 on page 40.

Weather control operation is described in pt.

9.3 on page 17.

Weather control is influenced by:

- heating curve setting,

- heating curve shift setting.

Preset temperature of water in heating circuit

is calculated automatically depending on the

external temperature value. Due to this,

proper selection of a heating curve will

guarantee room temperature stability –

independently of the external temperature.

This is why proper selection of a heating

curve is very important.

Fig. 17 Heating curves

Guidelines for proper setting of a heating

curve:

- floor heating 0,2 -0,6

- radiator heating 1,0 - 1,6

Guidelines for selecting a proper heating

curve:

- if at dropping external temperature, room

temperature increases, the selected heating

curve is too high,

- if at dropping external temperature, room

temperature also drops, the selected heating

curve is too low,

- if during frost, room temperature is proper

and too low when the weather is warmer, it

is recommended to increase heating curve

parallel shift and decrease the heating curve,

- if during frost, room temperature is too low

and too high when the weather is warmer, it

is recommended to decrease heating curve

parallel shift and increase the heating curve.

Poorly warmed buildings require setting

higher heating curves. Whereas for well

heating buildings, heating curve will have a

smaller value.

Preset temperature calculated from a heating

curve can be decreased or increased by the

controller outside maximum or minimum

temperature range for a particular object.

10.13 Room thermostat settings

In order to stabilize room temperature,

settings concerning room thermostat should

be made. Room thermostat complements

weather control and corrects water

temperature in the heating circuit in case

room temperature is still improper. It is

recommended to use the control panel as a

room thermostat. Room thermostat should

be assigned to each heating circuit. In order

to do this, set the parameter:

menu → service settings → H1,H2,H3 circuit

→ Room thermostat selection = Panel 1

Next, set the parameter:


→ Room thermostat function = temperature

correction

Set the proper parameter value:


→ room temperature correction

The higher room temperature correction

parameter value, the higher correction of

preset temperature of water in the heating

circuit. Caution: setting too high room

temperature correction value can lead to

cyclical value fluctuations.

Room thermostat has no influence on a set

temperature of water in the heat circuit when

room temperature correction = 0.

Room thermostat deactivation

26

In order to cause room thermostat to

influence the set temperature of water in the

heat circuit:

- set room temperature correction

parameter to 0 when room thermostat

function = correction, or

- set decrease from room thermostat to 0

when room thermostat function =

thermostat.

12 Electrical system

The controller is designed to be supplied with 230V~, 50Hz voltage. System features:

three-wire (with protective wire),

made in acc. with currently valid regulations.

Caution: electric shock risk. After disabling the controller with the use of a touch

screen, controller terminals are still under dangerous level of voltage. Therefore, prior

to commencing any assembly works, disconnect mains voltage and make sure that

there is no dangerous voltage on terminals nor cables.

Connection cables should not be in contact with surfaces of temperature exceeding their nominal

work temperature. Terminals located on the right side of the device and labeled as L, N, 1-25 are

purposed for connecting devices with mains supply of 230V~. Terminals 26–57 and RJ are

purposed for cooperation with low-voltage devices (under 12V).

Connecting mains supply 230V~ to terminals 26-57, terminal RJ or USB will

damage the controller and may cause electric shock!

Cables inserted into the controller should be threaded through cableways (3). Cableways should

be tightened. Make sure that cableways are tightened properly by pulling the cable – there must

be no possibility of pulling the cable out. In the case of insufficient cableways, the wires of the

36

side 230V can be introduced through a side opening (5). However, in this case to protect the

wires against pulling out of their enclosing the cable tray (4). Cable tray (4) should fully cover the

opening (5), so that the degree of protection IP device was preserved.

Insulation length of the cable external surface should be as short as possible (maximum 50mm).

In case longest insulation is necessary, the cables should be fastened together or with other

cables neat the terminal in order to prevent any contact with dangerous parts in case any cable

comes out of the terminal. Insulation length of cables entering terminals are listed in a table in

pt. 14. No folding of excessive cables nor leaving non-connected cables inside the controller is

allowed (a risk of contact with hot elements and elements under dangerous levels of voltage).

Connect protective cables to terminals labeled with the following symbol:

Maximum HUW

temperature 25 … 95 55°C

Maximum preset temperature of water in the tank. This parameter

determines the maximum temperature to which the HUW tank will

be heated while discharging exceeding boiler heat from a boiler or

solar collector. Setting too high value can lead to the risk of scalding

with HUW. Too low parameter value will eliminate a possibility of

discharging heat excess to the HUW tank when the boiler is

overheated. In installations including a solar system, too low value

will reduce heat contacts because the solar pump loads the HUW

tank to a Maximum HUW temperature. HUW system developer

should consider a possibility of the controller failure. Such failure

can cause heating the water inside HUW tank up to a hazardous

temperature causing a risk of scalding for users. Therefore,

thermostatic valves should be used as an additional protection.

If minimum pump revolutions > 0, solar pump revolutions

modulation function is enabled. Function enables to increase

reception of heat energy from the solar panel at low insolation.

Solar pump decreases its revolutions when difference between

the agent inside a solar circuit, e.g. glycol. Solar pump is

deactivated when solar panel temperature drops below Anti-freeze

cause considerable heat energy losses. When Anti-freeze (solar) =

“0”, anti-freezing function is disabled.

Maximum temperature 25 … 90 55°C

Maximum set temperature of water in the tank. This parameter

defines what temperature the HUW tank will be heated up to during

the solar collector is loaded. It is a very important parameter

because if it is too high, there could be a risk of burning with utility

water. In case of installations with solar system, too low value will

limit heat gains because solar pump loads the HUW tank to

Maximum HUW temperature. During designing a HUW system, a

possibility of regulator fault should be taken into consideration. As a

result of such failure, water inside the HUW tank can be heated up

to a temperature which is dangerous for users. Therefore, additional

protection should be used in a form of thermostatic valves.
