Automatic setting function
This function can switch off control circuits
that are not needed or are only needed later.
The control circuits are registered
automatically when their corresponding
sensors are connected and transfer
permitted measuring values. Control circuits
without sensor circuits are automatically
switched off without displaying an alarm.
The AUTO-SET function is activated every
time the mains voltage is switched on.
Automatic activation
If the AUTO-SET function is switched on by
parameter 14 in the SYSTEM level and the
commissioning date has not yet been saved,
then the sensors that are connected or
clamped off are registered automatically
every time the control unit is switched on.
During this period, the error messages of the
sensors (short circuit interruption) are
suppressed.
If the commissioning date was saved, a
changed sensor configuration can only be
confirmed via manual activation.
Manual activation
The AUTO-SET function can be activated
manually at any time. To do this, press the
rotary pushbutton when switching on the
control unit while the version is being
displayed. Keep the button depressed until
the AUTO-SET function in the display is quit.
The AUTO-SET function serves the following
sensor inputs:
– Outdoor sensor
– Flow sensor 1
– Flow sensor 2
– Tank sensor
Apart from that, the AUTO-SET function is
only carried out if the circuits in the following
levels that are allocated to the sensors were
parameterised accordingly.
For the tank sensor:
HYDRAULIC Level
Parameter 2 - DHW-charge pump function
set value OFF or 1 (DHW-charge pump)
For flow sensor 1:
HYDRAULIC Level
Parameter 3 – mixed circuit function 1 set
value OFF or 3 (mixed circuit)
For flow sensor 2:
HYDRAULIC Level
Parameter 4 – mixed circuit function 2 set
value OFF or 3 (mixed circuit)
Because a parameter setting is not changed
by the AUTO-SET function, the current
settings are checked beforehand. A change is
only made if one of the settings above is
changed. This means that the deeper system
configuration can never be changed by the
AUTO-SET function.
