TEMPERATURE
•
Boiler overheat temperature
– When the set boiler temperature is exceeded by this set value,
the boiler shuts off.
•
Boiler temperature hysteresis
– The boiler temperature hysteresis is used to set a temperature
difference between the temperature at which the heating
system is switched on and the temperature at which it is swit-
ched off (only for “Boiler activation on”).
•
Minimum return temperature
– Set the minimum return temperature. This limits the minimum
value of the return temperature in parameter
2-02
.
•
Combustion chamber temperature stop
– After the set temperature is exceeded, the heating system swit-
ches to the operating state Combustion chamber temperature
stop.

PARAMETERS
•
Dosage pause min. and dosage impulse min.
– These parameters are used to set the minimum pause intervals
and running time of the extraction for the fuel metering.
•
Feed system lag time
– This parameter determines the lag time of the rotary feeder
and the stoker auger. The continued running empties the
auger channel when the heating system is shut off.
•
Feeding system lead time
– After a prior Lambda stop, combustion chamber temperature
stop or material stop, the feed system starts early by the
amount of the set value.
