CE1 Duration of compressor ON time in the case of
faulty ambient probe
(emergency mode).
If CE1=0 the emergency mode in the presence of
error E0 remains disabled, the compressor remains
off and defrosting is prevented in order to conserve
the remaining cold.
0 – 240 min
0 = disabled
0 min
CE2 Duration of compressor OFF time in the case of
faulty ambient probe (emergency mode).
5 – 240 min 5 min
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 min 0 min
tdo Compressor restart time after door opening. when
the door is opened and after tdo time, it’s setted back
the normal functioning giving door open alarm (Ed)
If the door switch is closed and the light stays on for
a longer time than tdo light cell alarm is signaled
(E9). With tdo=0 the parameter is disabled.
0 – 240 min
0 = disabled
0 min
Fst FAN shutdown TEMPERATURE
The fans will stop if the temperature value read by
the evaporator sensor is higher than this value.

nSC Correction factor for the SET button during night
operation (energy saving)
(with In1 or In2 = 8 or -8)
During night operation the control set is:
Set Control = Set + nSC
In night mode decimal point flashes.
