Page 7: ECFWER(B)6 Controller - OM_tcm46-140438

The controller selects the cooling or heating mode basedon the temperature of the air compared to a neutraltemperature interval (neutral zone) centred on the setvalue of the thermostat.

The neutral zone is a parameter related to the function"automatic cooling/heating switching mode based on theair temperature".The neutral zone is a temperature interval astride the settemperature. When the air is warmer than the top limit ofthe neutral zone, the cooling mode is selected.When the air is cooler than the lower limit of the neutralzone, the heating mode is selected.The following figure illustrates an example with:

Neutral zone = 5°CSet room air temperature = 21°CFor temperatures above 23.5°C the cooling operatingmode is selectedFor temperatures below 18.5°C the heating operatingmode is selected.

On the controller, the range of the neutral zone is 2°C or5°C and can be defined by setting microswitch number 4(see "Setting the microswitches" on page 10).

The time function is used to start the fan at mediumspeed for 2 minutes at regular intervals (every 10minutes) once the room temperature has reached thelevel as set on the thermostat. It ensures the constantmonitoring of the air temperature in the room. It is onlyused in summer and only if the enabling signal of thewater temperature probe is positive.The time function cycle is also executed when thecontroller is powered (first start-up or voltage reset).

Automatic cooling/heating switching mode based on the air temperature

When this function is selected, thetemperature range of the thermostat refers tothe values indicated in figure 3, both forcooling and for heating.

In this type of configuration, the input for thecentralised cooling/heating switching mode isdisabled.

The thermostat controls an electric heater as integrationor replacement of a hot water heating system.When the operating mode selector switch is turnedto and the electric heater is turned on, the fan runscontinuously at medium speed.For safety reasons, the fan is turned off 2 minutes afterthe electric heater is turned off, whether this occurswhen the desired air temperature is reached or when theelectric heater is turned off manually using the operatingmode selector.

The controller starts the unit according to the followinglogic based on the water temperature that is detected bya dedicated probe:■ Water temperature <17°C: Cooling mode enabling

signal■ Water temperature >37°C: Heating mode enabling

signalIn installations with electric heater control, the sameprobe sends the enabling signal for the electric heater toturn on according to the following logic:■ Water temperature <37°C: Additional electric heater

enabling signal. (This enabling signal is sent only ifthe operating mode selector switch is turnedto ).

■ Water temperature >39°C: The additional electricheater is switched off.

Technical data and operation limitsElectric heater control

■ During operation of the electric heater, thefan runs at medium speed only.

■ During heating operation of 2-pipe systemunits equipped with an electric heater andmotorised valves, only the electric heaterworks.

AUTODIAGNOSIS PROCEDURE

For checking the correct operational efficiency of thecontroller when installing or for searching for possiblefaults, all outputs can be operated manually (fan, valves,electric heater) thanks to the autodiagnosis mode.Proceed as follows to access the autodiagnosis modeand to run the tests1 Turn the operating mode selector switch to the "OFF"

position.2 Turn the knob of the thermostat anti-clockwise until it

reaches the minimum temperature position.3 Hold the cooling/heating selector pushed for at least

5 seconds. At this stage both LEDs light up.4 Within 5 seconds, turn the knob of the thermostat

clockwise to the maximum temperature position. Thered LED switches off and the blue LED remains lit toindicate that the autodiagnosis mode has beenaccessed.

5 In the autodiagnosis mode, each position of theoperating mode selector switch corresponds to thesimulation of an output.

By running through the various positions of theoperating mode selector switch, the electroniccontroller outputs can be checked one after the othereither by observing the related component (valve,fan, electric heater) or by checking if thecorresponding terminals are powered at a voltage of230 V.

6 Exit the autodiagnosis mode by turning the operatingmode selector switch to the position.

NOTE If you wait more than 5 seconds beforeturning the knob again, the autodiagnosismode will be automatically exited.
