Installation

3.1

Choosing the right installation position

3.1.1 Installation in reference room 

If the system is room-temperature controlled, the following requirements must be observed:

• Installation position on an internal wall (

Æ

 Fig. 1)

• Maintain the specified distance from the door (to avoid draughts).

• Allow clearance below the programming unit (

Æ

 Fig. 1, shaded area) (to ensure correct 

temperature measurement).

• The reference room (= installation room) must be as representative as possible of the entire 

home. External heat sources in the reference room (e.g. sunlight or other heat sources such as 
an open fire) affect the control functions. This means it may be too cold in rooms without external 
heat sources.

• Always open the thermostatic radiator valves fully in the reference room to prevent the two 

temperature controllers influencing each other.

Fig. 1

Minimum clearances for installation in a reference room

If there is no suitable reference room, we recommend setting the system to weather-
compensated control instead (this requires an outside temperature sensor). 
Alternatively, you could install an external room temperature sensor in the room with the 
greatest heating requirements (e.g. living room).
