Boiler's status indicators
The boiler control uses the temperatures and flue gas values to detect the status
of the boiler.
Off
The boiler switches off if there is no demand from the heat circuits or HWTs or if
the accumulator takes care of the demand.
Ignition monitoring
Fuel is being transported into the combustion chamber and the boiler monitors if
an autonomous ignition is possible due to residual embers.
Ignition
The electric ignition starts and the fuel is ignited.
Combustion
The boiler controls the induced draft fan's output (air volume) according to the
heat demand and required boiler temperature, and the optimum fuel amount
according to the lambda sensor signal.
Combustion output range from 30 - 100 %
Burnout
The boiler controls the burnout according to the O2 content and the set minimum
and maximum burnout times.
