Manual call-up
SDC / DHC
Manual call-up of the AUTO SET function is always possible. The
call-up is activated by pressing the input button during the version
display until the AUTO SET function is shown in the display. The
basic display is activated after the function has been carried out.
A change in the function assignment by the AUTO SET function is
only carried out depending on the following inputs and selected
configuration:
Input
Only executed if:
Outside sensor (AF)
Flow sensor 1
(VF1)
MC1:
OFF/Mixed heating circuit
valve
Flow sensor 2
(VF2)
MC2:
OFF/Mixed heating circuit
valve
Tank sensor
(SF)
SLP:
OFF/Tank loading pump
Boiler sensor
(KF)
BR:
OFF/Single-stage
The current setting values are checked beforehand so that the
configuration carried out is not changed by the AUTO SET
function. A change is only carried out if one of the settings
specified above is applicable. This ensures that the AUTO SET
function cannot, for example, ever log off a return increase at the
MC2 or re-function it into a mixed heating circuit.

Emission measurement (not for DHC 43)
By pressing this key, the heat generator is controlled for 20
minutes according to the maximum temperature limit. The
remaining time is displayed and counted down.
With two-stage heat generators, both stages are in operation
(measurement at nominal power).
Function
The heat generator is adjusted to the maximum heat generator
temperature. All heating circuits and the hot-water production
adjust their setpoint to the respective maximum temperature.
ATTENTION
There is danger of scalding because the hot-water
temperatures may rise above the setpoint temperature.
Application
