gas temperature, the boiler will switch to normal
output control.

Flame monitoring

If the burning chamber temperature fluctuates
greatly during operation, the boiler will switch off.

Antifreeze

If  the  freezing  protection  operates,  the  back  flow
bypass  pump  will  switch  on  only if  the boiler is in
operating  mode  “HEATING  OFF”  or  “BURNER
STOP”.  Otherwise  (freezing  protection  disabled)
the  boiler  will  start  up  and  heat  up  to  minimum
boiler temperature 65 °C.

Lambda control

The amount of  material and the rotation speed of
the  ID-fan  are  controlled  by  the  lambda  control.
The control is able to detect marginal deviations of
the  fuel  quality  and  induces  a  combustion
improvement. Therefore, it is not necessary to re-
set the combustion after the silo is filled.
