but runs permanently both during the drawing of the ignition amount and during both the
times T4 and T6. Thus, the other external conveyor runs continuously and works independently
of the status of the actual output for the external worm conveyor. This means that if the output
to the main external conveyor from which pellets directly fall to the burner gets damaged, the
reserve will keep working independently. This function can be used in cases when you need to
control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet
bin at the boiler from which the main external conveyor draws pellets to supply them directly to
the burner. Caution - the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler.
j)
S14 = 10….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during
both the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in
dependence on the status of the actual output for the external worm conveyor. This means that if
the output for the external conveyor from which pellets fall directly to the burner gets damaged,
the reserve will be switched off automatically. This function is convenient in cases when you
need to control another external conveyor that supplies (feeds) pellets from a larger distance to
a pellet bin at the boiler from which the main external conveyor draws pellets to supply them
directly to the burner. Caution - the other external conveyor must always be controlled with an
additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the
boiler. This is a similar function to S6 = 9, but with a higher degree of safety.
k) S14 = 11….. Reserve function for controlling boiler exhaust fan for DCxxSP(X), CxxSP,
ACxxSP boiler types when the function for automatic start after wood is burnt out is activated.
This function ensures that boiler exhaust fan is running only during wood burning after the wood
is burnt out. When the burner is run on pellets, the boiler exhaust fan remains switched off. This
function is used if you do not need or want to use the boiler exhaust fan while the burner is running.
Install the AD02 module under the instrument hood of the boiler and connect it electrically between
the boiler terminal board and the extraction fan, see the wiring diagram.
WARNING – this is not a standard setting for DCxxSP(X), CxxSP, ACxxSP boilers with
the function of automatic start
(AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (standard setting is S6 = 4).
l) S14 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner
regulation (boiler terminal board). This function controls the pump in the boiler circuit without
using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with
wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, D80P, P80,
DxxPX, PXxx. Pump output must be switched to reserve R2 on the boiler terminal board and the
TK sensor must be installed before this function can be activated. After activation, S37, S38, S39,
S40 temperature parameters must be checked and configured.
m) S14 = 13…..Reserve function is the reverse output function for controlling the pump in
the boiler circuit from the burner regulation (output cable from boiler with a connector – white
inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using
AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.
