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.

7.1.6Minimum burner runtime

Function 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).

NOTE 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.
