PV 100a
Burner chooses the output level between preset min and max powers. When burning time has been
more then 30 min, next time burner takes one level up, when burning time has been less then 15
min, next time burner takes one level down.
Hold flame
T
he main idea of this state is to reduce the number of igniting cycles. This state can be turned on
automatically or manually in “hold flame” menu (ON/OFF/AUTO). If set to AUTO, burner goes to
“hold flame” when the time between two startups is less then 10 minutes for 2 times. When “hold
flame” lasts more then one hour, automatic mode is turned off and burner goes to “burn end” state.
In “hold flame” state new fuel is fed after every 127s and fan is working by speed given by par10.
End burn
In the end burn state all fuel inside the burning chamber and feeder tube must be burned - no more
fuel added from external auger. Internal feeder and fan keep on working as in previous states (“hold
flame” or “burning”). After the feeder has made periodically 15 half-rotations (par26), the feeder
starts working continiously until 32 half-rotations is made.
End blow
Only the fan keeps on working with speed shown in par9 to burn out all coals. Feeder is turned off.
This state lasts until no flame is recognized plus one minute.
