burner switch-off or enabling in case of the interruption of the heat 
generator sensor. 
 
 ATTENTION 
Only Ag (hard silver), Au (gold) or Ni (nickel) are to be used 
for the contacts. 
 
In case of a sensor short-circuit a relevant fault message appears 
and the burner is blocked. 
 
Burner enabling in case of a faulty heat generator sensor 
In case of a sensor short-circuit or interruption, a fault message 
appears upon simultaneous unlimited enabling of the burner. 
The control of the heat generator is carried out only manually by 
means of the mechanical boiler temperature controller (boiler 
thermostat) on the boiler panel according to the set value. 
 
 ATTENTION 
Activation of this setting is only permissible if an 
electromagnetic boiler temperature controller is connected in 
series with the burner phase and the boiler temperature is 
thus limited by this boiler temperature controller. Otherwise, 
there is the danger of boiler overheating.

7.1.6  Minimum burner runtime  
This function extends the burner runtimes and reduces the 
standby losses. After starting the burner, a minimum of the set 
time must elapse before the burner is deactivated again 
(regardless of the temperature increase). 
 
If the temperature in the heat generator exceeds the set heat 
generator maximum temperature limit, the minimum burner run 
time is stopped and the burner is switched off in advance.

7.1.7  Switching: Multi-stage heat generator/Switching differential 
The control unit offers independently adjustable switching 
differentials with reference to the same setpoint.
