DELIVERED CONDITION
If you give this parameter the value "ON", then all parameters
will be reset to their factory settings. All changes made will be
lost. Even the appliance type will need to be re-entered under the
"APPLIANCE TYPE" parameter.
The delivered condition only loads the default values; it does not
reset any component.
„
APPLIANCE TYPE
You can set the appliance type here.
Note
Changing the "APPLIANCE TYPE" parameter can result in
incorrect functioning of the appliance; it must therefore
be changed only by our service department. Therefore
this parameter can only be changed after entering the
customer service code.
The appliance type must be re-entered after the delivered con-
dition has been reinstated or after a new PCB has been fitted.
„ „ CONTRACTOR
„
ENTER CODE
When the numerical contractor code is entered here, all contrac-
tor parameters of the appliance become freely accessible. At the
factory, the "CODE" is set to 1000.
If the customer service code is entered at this point, further pa-
rameters reserved for service department become accessible.
Note
If there is no operating action after a certain period of
time, the control disables access to the protected param-
eters. In that case you will need to enter the contractor
code again.
„
FAULT SEARCH
„
FAULT LIST
The appliance records the faults that have occurred in a circular
memory. The programming unit shows the ten most recent entries
in the fault memory.
If one fault occurs several times, it will only be recorded in the
fault list on its first occurrence.
„ DELETE FAULT MEMORY
If you set the option "ON" in this parameter, the fault list is cleared.
„
STOP EVENT
All actual values and switching states of the appliance are re-
corded in a circular memory. With "STOP EVENT", the recording
stops and it may be possible to draw conclusions from it as to the
cause of the fault.
„ SWITCH ON MANUALLY
Here, you can switch appliance components or functions on man-
ually. To do so, you have to enter the customer service code.

„ NIGHT VENTILATION
„ WINDOW OPEN
„ EVAPORATOR
„ DEFROST END TEMP.
The evaporator stops defrosting if this temperature is reached
during the defrosting process. Never change this value.
„ MAX DEFROST DUR.
Evaporator defrost is terminated after the time set here has ex-
pired, and the appliance returns to its original operating state. If
the evaporator has not yet been defrosted, the defrosting process
is re-initiated. This process is repeated until the upper evaporator
temperature limit is reached or exceeded. If defrost is terminated
through the maximum defrost time 10 times in a row, a fault (F17)
is displayed.
„ BOOSTER REFR. GUARD
If, during the defrosting process, the condenser temperature falls
below the limit value defined under "BOOSTER REFR. GUARD",
the electric emergency/booster heater is switched on to stop the
heating water cooling down any further.
„ DEFROST STOP
If the condenser temperature still continues to drop after the elec-
tric booster heater has been switched on, there is a risk that the
condenser may freeze up. In this case, the defrosting process will
be terminated when the temperature defined under the "DEFROST
STOP" parameter is reached.
