Combined boiler controlled with a controller with manual (wood) and automatic (pellet burner) stocking
controlled on the basis two sensors on the first accumulation (buffer) tank (PF and FPF sensors).
The ACD 03/04 controller allows the burner operation (BRE) to be switched on and off as required by
the operator (for example when cleaning the boiler). Automatic start of the pellet burner after all wood
is burnt out (according to WF and AGF sensors). Switching sources - wood/pellets. It also controls the
operation of the pump in the boiler circuit (DKP), one heating circuit (MK1) and DHW heating tank
(boiler) (SLP).
With this connection, it is necessary to close the valve on the second accumulation tank when heating
with the pellet burner, so that both tanks are not charged at the same time or place the FPF sensor in
the middle of the accumulation tank (heating both tanks with a burner up to 1/2).
INFO - DCxxSP(X) and DCxxGSP boilers are factory equipped with installed AGF (Tsv)
and WF (Tk) sensors, which can be used (connected) to the ACD 03/04 controller.
