UP () and DOWN () keys.
When the parameter has been selected it is
possible to:
• view the setting by pressing the SET key.
• modify the setting by holding the SET key
down and pressing the () or () key.
2. When the configuration settings have been
completed, exit the menu by pressing the

them pressed until the room temperature
reappears.
3. Changes are saved automatically when you exit

List of Level 2 variables (Installer Level)
Variables Explanation Value Default
AC Door switch status 0 = normally open
1 = normally closed
0
F3 Fan status with compressor o 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 Not to be used
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 Correction of sensor signal -10 - +10 0
Pc Compressor protection contact status 0 = NO
1 = NC
0 = NO
doC Compressor safety time for door switch: when
the door is opened, the evaporator fans shut down
and the compressor will continue working for time
doC, after which it will shut down.
0…5 minutes 0
Fst Fan shutdown temperature
The fans will stop if the temperature value detected
by the evaporator sensor is higher than this value.
-45 - +45°C +45°C
Fd Fan dierential below Fst 0 - +10K 2K
