11.1 Automatic Set-Function
Function: This function allows to remove heating or hot water circuits from operation.
The control circuits are registrated automatically, if their corresponding sensors are
connected and provide acceptable measuring values. Control circuits without the
corresponding sensors remain automatically without consideration.
The automatic set function will be activated after every switch-on.
Automatical activation
Provided that the auto-set function is turned on (see SYSTEM-Level – parameter 14)
and the initial start-up date was not yet stored, connected or disconnected sensors
will be registered automatically at every switch-on of the control unit. During this time
error messages of sensors (short circuit or interruption) will be suppressed. After the
initial start-up date was stored, a modified sensor configuration can only be taken
over by manual activation.
The AUTO SET function can be enabled at any time again for a day (day change) by
the system parameter.
Manual activation
Manual call-up of the AUTO SET function is always possible. The call-up is activated
by pressing the pressure rotary transducer when activating (during segment test)
until the AUTO SET function is shown in the display. The basic display is activated
after the function has been carried out.
Furthermore the auto set function is carried out only, if the control circuits which are
assigned to the corresponding sensors were parameterised in the respective levels.
For the hot water sensor:
HYDRAULIC Level
Parameter 2 - Function DHW charging pump Setting range OFF or 1 (DHW charging
pump)
For the supply sensor 1:
HYDRAULIC Level
Parameter 3 - Function mix. heating circuit 1 Setting range OFF or 3 (mix. heating
circuit)
For the supply sensor 2:
HYDRAULIC Level
Parameter 4 - Function mix. heating circuit 2 Setting range OFF or 3 (mix. heating
circuit)
The auto set function registers the following sensors:
input Is only activated if:
Outdoor sensor (OS)
Flow sensor 1 (VF1) MC1: OFF / mixed circuit valve
Flow sensor 2 (VF2) MC2: OFF / mixed circuit valve
Hot water tank sensor (DHWS) DHW: OFF / DHW charging pump
Boiler sensor (BS) BURN: OFF / single stage
