AD02 or AD03 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.
This setting and connection with AD02 or AD03 module and special connector (jumper to main
switch) is standardly used for DCxxSP, CxxSP, ACxxSP boilers with the function for automatic
start after wood is burnt out activated (AUTOSTART – S34 = 1 or S34 = 2). Boiler exhaust
fan is running simultaneously with the pellet burner during the AUTOSTART function.
e) S6 = 5…… Reserve function as the output function for the Z1 ignition spiral when the reserve
copies the run of the ignition spiral.
f) S6 = 6….. Cleaning function of the combustion chamber or grill (flap). If the burner is in the
normal START, RUN and STOP mode, the output is not energized. The output is only energized
for the limited time T11, which continues immediately after the expiration of time T5 in the
STOP mode. It is not used with the A25 burner.
g) S6 = 7….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve output work independently of the condition of the actual output for the external worm
conveyor. This means that if the standard output for the external conveyor gets damaged, the
reserve will work independently in accordance with the same program, and therefore it can be
used as a replacement for the damaged output.
h) S6 = 8….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The
reserve 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 gets damaged, the reserve will be switched
off automatically. This function is suitable in situations when you need to control another external
conveyor that supplies (feeds) pellets from a larger distance to the main conveyor from which the
pellets fall directly to the burner.
i) S6 = 9….. 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 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) S6 = 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
