Controller operation 

 

Enable or disable of economy mode and change of set point, fan speed, controlling mode or any user operation 

can be done via parameter settings (see parameter P104 to P108, default is ON and key lock disabled). 

 

3.4.1

 

Operating mode 

The controller operating mode can be switched between 

Comfort 

and 

Economy Mode

 with the operating mode button 

( ). 

The controller is switched to 

Protection Mode

 by pressing the operating mode button ( ) for 2 seconds. 

 

Confort Mode 

Economy Mode 

Protection Mode 

 

 

 

 

 

If Economy mode is disabled (see parameter P103), the controller operating mode is switched between Comfort 

and Protection mode with the operating mode button ( ). 

 

Comfort Mode 

 

In Comfort mode, the controller measures the room temperature via built-in sensor or external room temperature sensor 

and maintains the temperature of the Comfort set point by controlling the fan speeds and the heating and/or cooling valve 

(or the electric heater). 
 

Economy Mode 

 

In Economy mode, the controller measures the room temperature via built-in sensor or external room temperature sensor 

and maintains the temperature of the Economy set point by controlling the fan speeds and the heating and/or cooling 

valve (or the electric heater). 
The temperature of the Economy set point depends on the controller configuration (see parameter P301 and P302). 
 

Protection Mode 

 

In Protection mode, the system is protected against frost (default 5 °C, see parameter P304) and protected against 

overheating (default OFF) (see parameter P303). 
 

3.4.2

 

Controlling Mode 

The controlling mode of the controller can be switched between 

Heating Mode

Cooling Mode

 and 

Fan Only

 by pressing 

the controlling mode button ( ). 
 

Heating Mode 

Cooling Mode 

Fan Only 

 

 

 

 

 

Depending on the configured application (see parameter P200)

cooling or heating can’t be selected as controlling 

mode. 

 

Heating Mode 

 

In heating mode, the controller measures the room temperature via built-in sensor or external room temperature sensor 

and maintains the requested temperature (according to the Operating Mode Comfort, Economy or manual setting), by 

controlling the fan speeds and the heating valve (or the electric heater). 
 

Cooling Mode 

 

In cooling mode, the controller measures the room temperature via built-in sensor or external room temperature sensor 

and maintains the requested temperature (according to the Operating Mode Comfort, Economy or manual setting), by 

controlling the fan speeds and the cooling valve.
