CONTROL MODULE Parameters
Parameters set
in
the module control the appliance
functions.
The minimum and maximum values for temperature are
preset
in
the module. Sensors monitor temperature and
the values are registered
in
the module. Where the sensor

this are calculated
in
the module.
Fridge door opening times and compressor run times are
monitored by the module. When the total
of
the door open
and compressor run times are equal to or exceed the
parameter values set
in
the eeprom, a defrost sequence
will be initiated.
COMPRESSOR OPERATION
1.
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.
8 minutes
The same minimum safety time is observed
in
the
Compressor Operation -
event of a mains power interruption (voluntary or
involuntary). This compressor protection strategy
is
observed only after the product has been operating

Long periods of activity: if the compressor remains

3.
Pause after defrost: at the end of the defrost cycle the
compressor observes a protection time parameterised
in
the module so that the water formed during defrost
can be completely drained.
