Manual call-upManual 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.

7.3.13.2Emission 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.
