Defrosting temperature
A defrosting operation is complete as soon as the
temperature set here is reached at the evaporator.
If the defrosting operation is not completed within
the time set in
, it will be stopped.
Defrosting time limitation
Here, you can set the max. time in which the
defrosting operation must be completed.
After the time set here, the defrosting operation will
be stopped even if the evaporator was not hot
enough to be free of ice.
No error message will be displayed.
Display of cold store temperature during
defrosting operation
It must be expected that the cold store temperature
will increase slightly during a defrosting operation.
If [
= 0], the actual cold store temperature will be
displayed during the defrosting operation.
If [
= 1], the temperature measured directly
before the start will be displayed until the cold store
setpoint is reached again after the end of the
defrosting operation. This is to avoid irritation of the
user during the defrosting phase. In the case of an
alarm, the display will be flashing and the actual
cold store temperature will be displayed.
Temperature difference for
refrigeration before defrosting
maximum refrigerating time for
refrigeration before defrosting
To avoid unnecessary heating up of the cold store,
you can set up a refrigeration cycle to be performed
before the defrosting operation.
Delay after compressor
stop before electric defrosting is started
If the compressor is on when an electric defrosting
request is received, the start of the defrosting
operation is delayed by the time specified here.
Drip time
Directly after the end of the defrosting operation,
the drip / dewatering time will start let the evapo-
rator drain. During this time, the compressor, defro-
sting and evaporator fan outputs are switched off.
Off-delay of drip tray heating
Here, you can define how long the drip tray heating
is to remain switched on after a defrosting operation
to avoid that the dripping water freezes again.

properly. This parameter is active only if the fan is
switched on from standstill.
Minimum speed
Here, you can set the lowest voltage value at which
a connected fan will still be running.
Evaporator fan:
Fan mode control mode
In this parameter, you can define how the fan is
switched on in control mode. If the controller is
performing a defrosting operation, the fan will be
controlled via parameter
. In the case of
continuous operation, the fan will be running as
soon as the controller is switched on. In the case of
continuous operation interrupted for draining, the
fan will behave like in the case of continuous
operation. However, it will be switched off for the
time set in
as soon as the defrosting operation
is complete. After the drain time set in
, the fan
will be switched on again. If the compressor is
switched on before this time has elapsed, the fan
will be restarted immediately (after the delay set in
). In the configuration with compressor On, the
fan will be switched on/off together with the
compressor. In order to avoid mains overload by
starting the compressor and fan at the same time, a
delay can be defined in
. The fan can also be
temperature-controlled. You can define if the
