Appliance Operations -
Parameters set in the module memory control the
appliance functions.
The minimum and maximum values for temperature are
preset in the module memory. Sensors monitor
temperature and the values are registered in the module.
Where the sensor values are outside the presets a
particular function will start or stop.
Where a sensor fails, open or closed, the appliance
operation will be controlled by time. The timed values for
this are calculated in the module memory.
The power module monitors door opening times and
compressor run times. When the total of the door open and
compressor run times are equal to or exceed the
parameter values set in the memory, a defrost sequence
will be initiated.
Compressor Operation -
There are situations of cooling
demand in which the compressor
remains off.
These are as follows:
Compressor protection: the compressor switches on
once a minimum safety time lag has elapsed since the
last power-off, thereby allowing refrigerant gas
pressure to reach a point of equilibrium in the
refrigerant circuit. The same minimum safety time is
observed in the event of a mains power interruption
(voluntary or involuntary).
Approximately 7 minutes
• Pause after defrost: at the end of the defrost cycle the
compressor observes a protection time parameterised
in the module memory so that the water formed during
defrost can be completely drained.
Approximately 7 minutes
