ALARMS AND SIGNALS
Signals
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, dripping will be in progress
Energy saving LED
If the LED is on and the dis
play 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
°C
Celsius degrees LED
If the LED is on, the unit of measurement for temperature is Celsius degrees
°F
Fahrenheit degrees LED
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 off
Signals
CODE
MEANING
Loc
the keyboard is blocked
- - -
the operation requested is not available
dEF
defrost is in progress
Alarms
CODE
MEANING
AL
Minimum temperature alarm in the compartment
Solutions:
- check the room temperature; see A1 parameter
Main consequences:
- the device will continue to operate normally
AH
Maximum temperature alarm
in the compartment
Solutions:
- check the room temperature; see A4 parameter
Main consequences:
- the device will continue to operate normally
id
Door switch input alarm
Solutions:
- check the causes of the activation of the input; see i0 and i1 parameters
Main consequences:
- the effect established with the i0 parameter
dFd
Defrost alarm switched off because maximum time has been reached
Solutions:
- check the integrity of the evaporator probe; see d2, d3 and d11 parameters
- touch a key to restore normal display
Main consequences:
- the device will continue to operate normally
When the cause of the alarm disappears, the device restores normal operation, except for the following alarms:
-
compressor shut down alarm (code “CSd”) which requires the switching off of the device or the temporary suspension of the power
supply.
- defrost alarm switched off becaus
e maximum time has been reached (code “dFd”) which requires the touching of a key
Errors
CODE
MEANING
Pr1
Room temperature probe error
Solutions:
- check that the probe is the PTC or NTC type; see P0 parameter
- check the device-probe connection
- check room temperature
Main consequences:
