LIST OF LEVEL 1 VARIABLES (User level)
LIST OF LEVEL 2 VARIABLES (Installer level)
VARIABLES MEANING VALUES DEFAULT
AC Door switch status (with door closed)
0= normally open
1= normally closed
0
F3
Fan status with compressor off
0 = Fans run continuously
1 = Fans only run when compressor is
working
1
F4 Fan pause during defrost
0 = Fans run during defrost
1 = Fans do not run during defrost
1
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.
0 = evaporator sensor present
1 = no evaporator sensor
0
d1
Defrost type, cycle inversion (hot gas) or with heater
elements
1= hot gas
0= element
0
Ad
Net address for connection to TeleNET supervision system
or Modbus
0 ÷ 31 (with AU=3)
1 ÷ 247 (with AU=7)
0
Ald
Minimum and maximum temperature signalling and alarm
display delay
1…240 min 120 min
C1
Minimum time between shutdown and subsequent
switching on of the compressor.
0…15 min 0 min
CAL Cold room sensor value correction -10…+10 0

VARIABLES MEANING VALUE DEFAULT
r0 Temperature difference compared to main SETPOINT 0.2 - 10 °C 2°C
d0 Defrost interval (hours) 0 - 24 hours 4 hours
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)
-35 - 45 °C
15°C
d3 Max defrost duration (minutes) 1 - 240 min 25 min
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.
0 - 10 min
0 min
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.
0 - 10 min
0 min
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.
- -45°C
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.
- +45°C
tEu
Evaporator sensor temperature display
(displays nothing if dE =1)
