Fault
codes
Description Possible cause
37 Fan speed too low.
There is an obstacle in the heat
pump’s air fl ow.
The fan motor is defective or
disconnected.
42
Product coding resistor
error.
The product coding resistance is
missing or defective.
The resistance value is outside
the authorised limits.
Fault
codes
Description Possible cause
86

heat contact is open.
The heated fl oor temperature is
too high.
The fl ow rate of the installation
hydraulic circuit is too low.
The heated fl oor circuits are
closed.
103
