PF
Power supply cut-off during execution of a cycle alarm
Solutions:
- check the device-power supply connection
COH
Condenser overheated alarm.
Solutions:
- check the temperature of the condenser
- check the value of the parameter C6.
Main consequences:
- the condenser fan will be switched on
CSd
Compressor blocked alarm.
Solutions:
- check the temperature of the condenser
- check the value of parameters C7 and C8
- disconnect the device power supply and clean the condenser.
Main consequences:
- if the error occurs during an operating cycle, the cycle will be interrupted
PD
Pump-down alarm
Solutions:
- check the maximum pump-down time established with parameter u2
- the alarm will be rearmed on the successive activation of the compressor or by pressing the
buzzer silencing key
Main consequences:
- compressor switch-off
Pr1
Cabinet probe error.
Solutions:
- check the value of the parameter P0
- check the integrity of the probe
- check the device-probe connection
- check the temperature of the cabinet.
Main consequences:
- if the error occurs during the “stand-by” status, no operating cycles can be started
- if the error occurs during a cycle, the cycle will be interrupted
Pr2
Evaporator probe error.
Solutions:
- the same as the cabinet probe error (“Pr1” code) but relative to the evaporator probe.
Main consequences:
- if parameter P3 is set at 1, the defrosting period will last for the amount of time set with
parameter 3
Pr3
Condenser probe error.
Solutions:
- the same as the cabinet probe error (“Pr1” code) but relative to the condenser probe.
Main consequences:
- the condenser fan will operate parallel to the compressor
- the overheated condenser alarm (“COH” code) will never be activated
- the compressor blocked alarm (“CSd” code) will never be activated
