Variables Meaning
Temperature difference compared to main SETPOINT
r0
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 defrost is stopped on time set by the d3
parameter)
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.
Minimum temperature alarm
A1
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)
To access the second programming level press the UP () and DOWN () keys and the LIGHT key
simultaneously for a few seconds.
When the first programming variable appears the system automatically goes to stand-by.
1. Select the variable to be modified by pressing the UP () and DOWN () keys.
When the parameter has been selected it is possible to:
2. View the setting by pressing the SET key.
3. Modify the setting by holding the SET key down and pressing the () or () key.
4. When configuration settings have been completed you can exit the menu by pressing the () and
() keys simultaneously and keeping them pressed until the room temperature reappears.
5. Changes are saved automatically when you exit the configuration menu.
6. Press the STAND-BY key to enable electronic control.
Variables Meaning
F3
Fan status with compressor off
F4
Fan pause during defrosting
F6
Evaporator fans activation for air recirculation.
The fans are activated for a time defined by F7 if they
have not started operating for the time F6. If the time
of activation coincides with the defrost phase,
the defrost end is still awaited.
F7
Duration of activation of the evaporator fans for air
recirculation
Fans working time for F6
Evaporator probe presence
dE
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.
