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 indepen-
dently
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 pel-
let 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.

….. 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 de-
pendence 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.

….. Reserve function for controlling boiler exhaust fan for DCxxSP 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. It is not used with the A45 burner.
WARNING
– this is not a standard setting for DCxxSP boilers with the function of auto-
matic start
(AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (standard setting is S6 = 4).

…..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. D31P, P31. Pump output must be switched to re-
serve 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.

…..
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.
