Door switch input alarm
Solutions:
id
- check the causes of the activation of the input; see i0 and i1 parameters
Main consequences:
- the effect established with the i0 parameter
Multifunction input alarm or pressure switch alarm
Solutions:
iA
- check the causes of the activation of the input; see i0 and i1 parameters
Main consequences:
- the effect established with the i0 parameter
Condenser overheated alarm
Solutions:
COH
- check the condenser temperature; see C6 parameter
Main consequences:
- the device will continue to operate normally
Compressor shut down alarm
Solutions:
- check the condenser temperature; see C7 parameter
CSd
- switch the device off and back on again: if when the device is switched back on, the temperature of the condenser is still
higher than that established in C7 parameter, disconnect the power supply and clean the condenser
Main consequences:
- the compressor will be switched off
Defrost alarm switched off because maximum time has been reached
Solutions:
- check the integrity of the evaporator probe; see d2, d3 and d11 parameters
dFd
- 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 because maximum time has been reached (code "dFd") which requires the touching of a key.
CODE MEANING
Room temperature probe error
Solutions:
- check that the probe is the PTC or NTC type; see P0 parameter
- check the device-probe connection
Pr1
- 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 1 or 2 and F0 parameter is set at 3 to 4, the device will operate as if parameter were set at 2
- if P4 parameter is set at 3, the condenser overheated alarm (code "COH") will never be activated
- if P4 parameter is set at 3, 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
- pre-dripping 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 progress
