- check that the probe is the PTC or NTC type; see P0 parameter
- check the device-probe connection
- check room temperature
Main consequences:
- compressor activity will depend on C4 and C5 parameters
- the defrost will not be activated
Evaporator probe or condenser probe error
Solutions:
- the same as in the previous example, but with regard to the evaporator probe or the condenser probe
Main consequences:
Pr2
- if P4 parameter is set at 1, the defrost interval will last for the amount of time set with d3 parameter
- if P4 parameter is set at 1 and d8 parameter is set at 2 or to 3, the device will operate as if d8 parameter were set at 0
- if P4 parameter is set at 2, the condenser overheated alarm (code "COH") will never be activated
- if P4 parameter is set at 2, the compressor shut down alarm (code "CSd") will never be activated
When the cause of the error disappears, the device restores normal operation.
LED
MEANING
Compressor LED
If the LED is on, the compressor is on
If the LED is flashing:
- the working setpoint is in the process of being set
- a compressor protection will be in progress
Defrost LED
If the LED is on, defrost is in progress
If the LED is flashing:
- defrost will be requested but a compressor protection will be in progress
- dripping will be in progress
- defrost will be requested but a compressor minimum switch-on shall be in pro
Evaporator fan LED
If the LED is on the evaporator fan will be on
If the LED is flashing evaporator fan standstill will be in progress
Energy saving LED
If the LED is on and the display is switched on, the "energy saving" function is in progress
If the LED is on and the display is switched off, the "low consumption" function is in progress; touch a key to restore
normal display
LED service
If the LED is on, service for compressor will be required
Celsius degrees LED
°C
If the LED is on, the unit of measurement for temperature is Celsius degrees
Fahrenheit degrees LED
°F
If the LED is on, the unit of measurement for temperature is Fahrenheit degrees
LED on/stand-by
If the LED is on, the device is switched

MEANING
Minimum temperature alarm
Solutions:
AL
- check the room temperature; see A1 parameter
Main consequences:
- the device will continue to operate normally
Maximum temperature alarm
Solutions:
AH
- check the room temperature; see A4 parameter
Main consequences:
- the device will continue to operate normally
