8.5 Positioning
The room thermostat must be installed in a position
which ensures a correct functioning. Generally, the
most suitable installation site is in the main living room,
at a height of 1.5 m. There, the room thermostat
is to be exposed to the circulating room aire without
obstruction by furniture curtains or other objects.
The room thermostat must be positioned so as to
ensure that neither draughts from windows or doors
not heat sources such as radiators, chimney breasts,
TV sets or sunlight can directly affect the room
thermostat. In the room in which the room thermostat is
installed, all radiator valves must always be fully open.

8.6 Installation sequence

We recommend to install the connecting cable to the
THERMOcompact/COMBlcompact before mounting
the front casing of the room thermostat. To fix it,
proceed as follows:
a) Take off the front casing (1) of the room thermostat
by means of a screw driver, removing it out of the
retaining cams (3) on the mounting plate (2).
b) Drill two holes with a diameter of 6 mm as shown in
figure 8 and insert the attached plugs.
c) Fix the mounting plate to the wall with the two
supplied screws.
