3.. Burnout
Combustion is stopped. The transport of pellets into the burner pot
is stopped, the forced draught fan continues to run until the remain-
ing pellets are burnt and the burner pot has cooled down sufficiently
(Fig. 27).
3.. Burner OFF
The control unit is sending a heat demand signal, but the boiler tem-
perature (actual value) is higher than the boiler temperature setpoint.
For this reason the combustion is stopped and the burner is off (Fig.
28).
