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) S6 = 11
….. 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).
l) S6 = 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. 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.
m) S6 = 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.
This me-
thod of pump controlling can be used for any ATMOS pellet boiler, and is therefore recom-
mended.
AD02 or AD03 modules must be inserted and connected under the boiler hood 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.
n) S6 = 14
….. Reserve function for direct control of solar heating pump from the burner regulation
(boiler terminal board). This function control solar pump when automatic sensor switching functi-
on is activated (S15=3), where the boiler is connected with accumulation tank equipped with solar
exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected to the
TSV solar panel. This function never uses AD02 or AD03 modules.
After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked
and configured.
This function is specially designed for boilers: D30P, D31P, P31 a D45P
