Circulating pump
error
CIRCULATING PUMP PRINTED
CIRCUIT BOARD (PCB) (*1)
Check pump voltage
If the voltage is within the standard values, the pump does
not need to be replaced. If the voltage is not within the
standard values, replace the printed circuit board (PCB).

WATER PUMP BLOCKED
WATER CIRCUIT BLOCKED
Check the pump and the water cir-
cuit.
Remove any obstructions, clean the water filter, unblock the
pump.
P3
High pressure
switch error
High pressure switch
Check loose cable connections and
contacts
if the same error appears again replace the
high pressure
switch

Below-normal tem-
perature measured
THE OUTSIDE TEMPERATURE
FALLS BELOW -20°C
The unit should not be operated
below -20°C to protect the various
components
When the temperature increases again, the unit automati-
cally resumes operation

OUTSIDE TEMPERATURE PROBE
Check resistance using a tester
[see table 1]
Replace the probe if faulty
No cooling
No heating
4-WAY VALVE Check resistance using a tester If the value is not within the standard range, replace the coil

PROBE
Check resistance using a tester
[see table 1]
If one of these probes is faulty, replace it

GAS LEAK
Check the service valve and the
refrigerant circuit.
After having repaired the leak, collect all the refrigerant and
then recharge to the specified mass
0011-0031
WATER CIRCUIT BLOCKED
Check the temperature difference
between water outlet and return.
If the difference is high it means
that water flow-rate is too low.
Remove obstructions, clean the water filter and unblock the
pump.
