b)
S14 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will
be opened and the reserve output will not be energized. Thanks to this a signal can be sent to an
electrically backed up AB01 ATMOS GSM module controller that will send information that there
is a system fault or the system is not energized. This is the opposite logic (to S14 = 1), which
means that during normal operation the reserve is energized.
c)
S14 = 3…… The reserve function as the output function for the burner fan, when the
reserve output is closed, is energized always when the burner fan is running (fan mode only
100 % or OFF). This function is applied if you want the boiler fan or extraction fan in the chimney
to run together with the burner fan. This function is designed for direct control of an fan directly
from the burner (e.g. D80P, P80, DxxPX, PXxx).
d) S14 = 4…… The reserve function as the reversed function of the output for the burner fan,
when the reserve output is off, is not energized always when the burner fan is running. This
function is always activated if you connect the A25 burner with the AS25 set containing the
AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the
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(X), 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) S14 = 5…… Reserve function as the output function for the Z1 ignition spiral when the reserve
copies the run of the ignition spiral.
f) S14 = 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) S14 = 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) S14 = 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) S14 = 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,
