The boiler is ventilated, the sealing slider is opened and the Lambda
probe is heated.
The combustion chamber is filled with pellets.
The fan-assisted ignition switches on and the pellets are preheated until
a bed of embers is formed. For this period loading is deactivated.
The pellets are ignited with the fan-assisted ignition. The flame is
distributed around the whole combustion chamber. The control of the
loading unit is defined as "Ignition" in the parameter menu.
The Lambdatronic controls combustion according to the boiler set-points.
The boiler has no power consumption. The ID fan and the loading unit
are deactivated.
The Lambdatronic carries out the cleaning program (duration approx. 3
min).
When the boiler is interrupted during the heating up procedures (heating
up, pre-heating, ignition), it waits for a specified period of time until the
next start attempt.
The ID fan runs to burn the remaining pellets.
The loading unit is deactivated.
The system is still ventilated by chimney draught. The loading unit is
deactivated.
CAUTION-Fault persists!
