f)
S68 = 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 (setting is S68 = 4).
g) S68 = 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, DxxPX,
PXxx. Pump output must be switched to reserve R5 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.
h) S68 = 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 method of pump controlling can be used for any ATMOS pellet boiler, and is therefore
recommended. 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.
i) S68 = 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 function
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: D14P, P14, D15P, P15, D20P, P20, D21P, P21,
D25P and P25
CAUTION - the direct controlling function of solar heating from pellet burner cannot be
used for
DCxxSP(X)/(EP), CxxSP, ACxxSP
boilers and boilers with burner built into the
upper doors. This function also cannot be used when the pump is simultaneously controlled
in the boiler circuit from the burner regulation (TK sensor cannot be simultaneously in boiler
and accumulation tank)
j) S68 = 16….. Reserve function for controlling el.fan during the function for automatic burner
cleaning using compressed air. This function is connected with S67 (S68), S41, S42, S43, S44,
S45, S46, S47 parameter, which must be checked and configured.
