LIST OF LEVEL 2 VARIABLES (Installer level)
Fan status with compressor off
0 = Fans run continuously
1 = Fans only run when compressor is
working
2 = Fans disabled
0 = Fans run during defrost
1 = Fans do not run during defrost
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.
0 – 240 min
0 = (function not activated)
Evaporator fans duration for air
recirculation. Fans working time for F6
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
Defrost type, cycle inversion (hot gas) or
with heater elements
0 = heating element
1 = hot gas
2 = heater with temperature control
0 = disabled
1 = defrost at power-on (if possible)
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.
Display viewing during Defrost
0 = current temperature
1 = temperature at the start of the defrost
2 = “DEF”
