List of level 1 variables (user level)

Variables Meaning
r0 Temperature difference compared to main SETPOINT
d0 Defrost interval (hours)
If d0 = 0 cyclical defrosts Off
d2 End-of-defrost setpoint.
Defrost is not executed if the temperature read by the defrost sensor is greater than
d2. (If the sensor is faulty defrosting is timed)
d3 Max defrost duration (minutes)
d7 Drip duration (minutes)
At the end of defrost the compressor and fans remain at standstill for time d7, the
defrost LED on the front panel flashes.
F5 Fan pause after defrost (minutes)
Allows fans to be kept at standstill for a time F5 after dripping. This time begins at the
end of dripping. If no dripping has been set the fan pause starts directly at the end of
defrost.
A1 Minimum temperature alarm
Allows user to define a minimum temperature for the room being refrigerated. Below
value A1 an alarm trips: the alarm LED flashes, displayed temperature flashes and the
buzzer sounds to indicate the problem.
A2 Maximum temperature alarm
Allows user to define a maximum temperature for the room being refrigerated. Above
value A2 an alarm trips: the alarm LED flashes, displayed temperature flashes and the
buzzer sounds to indicate the problem.
tEu Evaporator sensor temperature display (displays nothing if dE =1)

List of level 2 variables (installer level)

Variables Meaning
F3 Fan status with compressor off
F4 Fan pause during defrost
F6 Evaporator fans activation for air recirculation.
The fans activate for a time defined by F7 if they have not started working for the F6
time. If activation time coincides with the defrosting time, end of defrosting is awaited.
F7 Evaporator fans duration for air recirculation.
Fans working time for F6
dE Sensor presence
If the evaporator sensor is disabled defrosts are carried out cyclically with period d0:
defrosting ends when an external device trips and closes the remote defrost contact or
when time d3 expires.
d1 Defrost type, cycle inversion (hot gas) or with heater elements
dPo Defrost at Power On
dSE Smart defrost
dSt Smart defrost Setpoint (if dSE=1)
The counting of the time between the defrost is incremented only if the compressor is
ON and the evaporator temperature is less than dSt.
