This function determines a room temperature-related limit with 
adjustable switching differential. If the room temperature of the 
relevant heating circuit exceeds the current daytime or reduced 
room setpoint by the set switching differential, heating is 
temporarily stopped (heating circuit pump switched off). 

Heating is resumed as soon as the room temperature of the 
respective heating circuit drops 0.5 K below the switch-off 
temperature. 

 

Daytime room setpoint = 22°C 

Thermostat function set value = 4 K 

Interruption of heating:

Room

 > (22°C + 4 K) > 26.0°C 

Resumption of heating:

 > (26°C – 0.5 K) < 25.5°C 

 

Set value OFF disables the thermostat function. 

 

The thermostat function is effective while heating and in reduced 
mode.  

 

The thermostat function is disabled when outside temperature 
frost protection is active.
