Solution
Adjust combustion air (can only be
done by an expert).
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 temperature
regulator -1S3.1 is functioning, if
necessary it has to be exchanged.
Check the terminal strip X1 with a
voltage tester (see wiring diagram)
to see whether the ventilator drive
is being supplied with electricity.
Terminal 4 and 6N (see wiring
diagram).
