Room thermostat function (maximum room temperature limit)
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.
Example:
Daytime room setpoint = 22°C
Thermostat function set value = 4 K
Interruption of heating:
T
> (22°C + 4 K) > 26.0°C
Room
Resumption of heating:
T
> (26°C – 0.5 K) < 25.5°C
Room
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.
