11.4.1 Room thermostat
The room thermostat is optional. Select an appropriate place for the room thermostat by following these rules:
• Central room
• Installation height, approx. 1.5 m
• Inner wall
• Away from drafts
• Away from direct sunlight
• Do not install the thermostat behind a door or in any other place where it may receive shocks.
Air tightness faults in buildings often result in cold air
being blown through the electrical sheathing. Do not
hesitate to seal them off if a cold air draft comes into
the back of the thermostat.
