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: 

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. 

 

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). 

 

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.
