10.8 Maximum room influence setting
The maximum room [ambient] influence limits the influence of the room
temperature (room temperature hook-up) on the set flow temperature.
The value determines the maximum room temperature setback for
rooms which are not equipped with remote controls.

Explanation
Outside
setback
Outside setback
determines the outside temperature
limit. The heating circuit is switched off when this
value is exceeded. Below this limit, the heating system
heats to the set night temperature.
Room setback
Hold room temp
determines a night temperature as
the room temperature. The heating circuit is switched
off when this value is exceeded. Below this limit, the
heating system heats to the set night temperature. For
this function a remote control must be located in the
relevant room.
Off
In
Standby
mode, the heating circuit is generally
switched off in standby.
Reduced
In
Reduced
mode, the system heats to the set night
temperature if setback mode is selected. The heating
circuit pumps operate constantly.
Room

Setting the heating system to
