Troubleshooting
To troubleshoot, proceed as follows:
Some models are not equipped with a HPS.
Check the connections of the
high pressure systems.
Is HPS
correctly connected to
the outdoor unit
PCB?
Connect correctly.
Ÿ
Turn the power OFF and back
ON after 2 or 3 minutes.
Ÿ
Check the continuity of the HPS
for control and safety.
Does the HPS have
continuity?
Replace HPS
without continuity.
Check high
pressure during
operation.
Tc(HP) > Ta 35°C
set value 1 > HP > set value 2
Replace outdoor
unit PCB.
No
Yes
No
No
Yes
Is the unit in
cooling mode?
No
Check high
pressure during
operation.
Tc(HP) > Ta o 30°C
set value 1 > HP > set value 2
Replace outdoor
unit PCB.
Faulty refrigerant
piping circuit.
No
Yes
Yes
Yes
Faulty refrigerant
piping circuit.
Tc(HP) = heat exchanger temp.
Ta indoor = indoor air temp.
Ta outdoor = outdoor air temp.
HP = high pressure
set value 1 = max. pressure
set value 2 = min. pressure
Refer to high pressure settings
