Cause
Consequences
System status / Solution
12
Water temperature too
cold (T< 5°C)
PDC stoppage.
Central heating / C.H. in ELEC.
Automatic resetting as soon as T>10°C. Check
installation compliance (room protected
against freezing).
15
Date and time not set
PDC Se PROG stop
Enter date and time.
21
Faulty air inlet probe
or out of measurement
range (from -20 to
60°C)
PDC stoppage.
Central heating / C.H. in ELEC.
Check the connections (reference A4) and
the positioning of the inlet air probe. Check
the resistance of the probes (see table below).
If necessary, replace the probe bundle.
After solving the fault, the heat pump will be
restored within 2 hours.
22,1
Faulty high evaporator
probe or out of
measurement range
(from -20 to 110)
PDC stoppage.
Central heating / C.H. in ELEC.
Check the connections (reference A4) and the
correct application of the probe on the pipe.
Check the fan operation and that it turns freely
without stopping (reference M1) and the power
supply on the terminal board
Check the resistance of the probes (see table
below).
22.2
Faulty low evaporator
probe or out of
measurement range
(from -20 to 110)
PDC stoppage.
Central heating / C.H. in ELEC.
Check the connections (reference A4) and the
correct application of the probe on the pipe.
Check the fan operation and that it turns freely
without stopping (reference M1) and the power
supply on the terminal board
Check the resistance of the probes (see table
below).
25
Compressor thermal
safety or pressure
switch opening
PDC stoppage.
Central heating / C.H. in ELEC.
Check the connections of the compressor
(Reference R1), of the pressure switch, of the
starting condenser (15mF) and of the hot gas
valve (Reference T2). Check the resistances
of the compressor coils.
28
Defrosting system
error
PDC stoppage.
Central heating / C.H. in ELEC.
Check the evaporator cleanliness
Check the R513A fluid load (appliance
defrosted).
Check the fan operation (reference M1) and
the power supply on the terminal board.
Check the condensate drain.
Check the hot gas valve connections (refer-
ence T2) and its operation (TEST menu).
W.30.1
Inefficient PDC
heating
PDC stoppage.
Central heating / C.H. in ELEC.
Check the load.
Check the ventilation operation (reference
M1) and the power supply on the terminal
board
W.30.2
Inefficient PDC
heating
PDC stoppage.
Central heating / C.H. in ELEC.
Check the load.
Check the ventilation operation (reference
M1) and the power supply on the terminal
board
W.30.3
Faulty pressure reducer
PDC stoppage.
Central heating / C.H. in ELEC.
Check that there is no frost on the pipe
between the pressure reducer and the
evaporator.
Check the load.
If it is charged, replace the pressure reducer.
