Solution
Fit the room thermostat at another
place. It is important, for proper
controlling, that the room thermostat if
fitted in the room to be heated, should
be fitted in such a way that no flow of
cold air from windows, doors etc.
comes into contact with it. If
appropriate, move the room thermostat
to another place.
Examine the room thermostat (can
only be done by an expert), change it
in emergency cases.
Move the thermostat to another place
Check, whether the
regulator 3S2.1 is functioning,
necessary it has to be exchanged.
Check the terminal strip X2 with a
voltage tester (see wiring diagram) to
see whether the ventilator drive is
being supplied with electricity.
