Start of refrigeration when the door is open. If the
door has been left open, refrigeration will be started
after the set time.

Readout of the actual control state of the controller
0=Normal ctrl., 1=Hold after defrost, 2=Min ON timer,
3=Min OFF timer, 4=Drip o, 10=Main switch OFF,
11=Thermostat cut-out, 12=Frost protection S4,
14=Defrost, 15=Fan delay, 17=Door open, 18=Melt

0=None, 1=Electrical, 2=Hot gas, 4=Air/Ocycle
Here you dene whether a defrost cycle is to be stop-
ped by time or by a temperature sensor
0=Time, 1=S5 sensor, 2=S4 sensor
When the selected defrost stop sensor reaches the set
limit, the defrost cycle is terminated
Defrost stop temperature limit when thermostat band
2 is in operation.When the selected defrost stop sen-
sor reaches the set limit, the defrost cycle is termina-

Min. duration of a defrost cycle. The defrost cycle will
as a minimum run for the set minimum defrost time
once it is started
Max. duration of a defrost cycle. The setting is also
used as a safety time if the defrost is stopped on tem-
perature. If the selected defrost stop sensor does not
reach the set defrost stop temperature limit within
the set time, the defrost will be stopped anyway.
Max duration of a defrost cycle when thermostat
band 2 is in operation. The setting is also used as a
safety time if the defrost is stopped on temperature. If
the selected defrost stop sensor does not reach the
set defrost stop temperature limit within the set time,
the defrost will be stopped anyway.
The function is zeroset and will start the timer func-
tion at each defrost start. When the time has expired
the function will start a defrost. The function is used
as a simple defrost start, or it may be used as a safe-
guard if the normal signal fails to appear. If master/
slave defrost without clock function or without data
communication is used, the interval time will be used
as max. time between defrosts. If a defrost start via
data communcation does not take place, the interval
time will be used as max. time between de-
frosts.When there is defrost with clock function or da-
ta communication, the interval time must be set for a
somewhat longer period of time than the planned
one. In connection with power failure the interval
time will be maintained, and when the power returns
the interval time will continue from the maintained
value. he interval time is not active when set to 0
