15 ERRORS
15.1 Errors
The following table shows the meaning of the error codes of the device.
CODE MEANING
Pr1
room temperature/inlet air temperature probes error
Solutions:
- check that the probe is the PTC or NTC type; see parameter P0
- check the device-probe connection
- check room/inlet air temperature
Main consequences:
- compressor activity will depend on parameters C4 and C5
- the defroster will not be activated
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
- the door heating elements will be switched off (only and provided parameter u1 and/or parameter u11 is set
at 4)
- the neutral area operating heating elements will be deactivated (only if parameter u1 and/or parameter u11
is set at 5)
- if parameter P4 is set at 3, the temperature associated to regulation will be that detected by the outlet air
temperature probe
Pr2
Evaporator temperature probe error
Solutions:
- the same as the preceding case but with respect to the evaporator temperature probe
Main consequences:
- if parameter P3 is set at 1, the defrosting period will last for the amount of time set with parameter 3
- if parameter P3 is set at 1and parameter d8 is set at 2 or to 3, the device will operate as if parameter d8
were set at 0
- if parameter F0 is set at 3 or 4, the device will operate as if the parameter were set at 2
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
Pr3
Auxiliary temperature probe error
Solutions:
- the same as in the previous example, but with regard to the auxiliary temperature probe
Main consequences:
- if parameter P4 is set at 1:
- condenser overheated alarm (code “COH”) will never be activated
- he compressor blocked alarm (code “CSd”) will never be activated
- the condenser fan will operate parallel to the compressor (only if parameter u1 and/or
parameter u11 is set at 6)
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
- if parameter P4 is set at 3, the temperature associated to regulation will be that detected by the inlet air
