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

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

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
