Test blowing time defines how long boiler and chimney should be
ventilated before combustion may start (10-100 seconds).
For boilers where it is difficult to get their self-draught started, it
is suitable to increase the burners test blowing time: Factory-set to
15 sec.
Here you can choose the length of time from the first detection of
flame until full pellets feeding in the output mode selected .
There are two parameters for the transitional time: one for 10 kW
and one for 20kW. The time ser for the first parameter determines
how long it will take to obtain 10kW, the time for second
parameter how long it will take to obtain 20kW, after the flame
was detected. The lower the desired output, the shorter the time
needed to obtain this output.
Here you can adjust the amount of pellets fed during the
transitional phase which lasts from the first detection of flame
until the burner reaches 10kW output.
Adjust the desired amount fed to the burner after the detection of
flame. The amount supplied will be increased in every feed
sequence during the time set. Factory settings are 15% of full
amount at 10kW.
Clean-blowing is ativated when the thermostat has cut out and the
photocell value drops below 12%. Here you can also determine
when the ash removal should take place. When the thermostat cuts
in or wheather it cuts out.
The clean-blowing parameter includes a sub-parameter for the
cleaning the grate (ash removal). Either after completed burn-
down or when the thermostat cuts in.
Here you can adjust the photocell sensitivity, i.e. at which light
value (in %) the control system should assume that there is a
flame.
Flame sensitivity should not need to be adjusted if the correct
photocell is installed. Factory settings: 50%.
