18 . Connection of boilers DCxxS, CxxS(T), ACxxS, KCxxS, DCxxRS
with built-in burner in upper doors with buffer (accumulation)
tank for regulation of the burner based on sensors TS and TV
and control of boiler pump based on TK sensor
INFO - Boilers with modification for the pellet burner are from 1st of March equiped from
the production with two AD03 modules, changeover switch (I/0/II), boiler temperature sensor
TK (KTF 20), pump thermostat - 70 °C and with the outlet for the pump in boiler circuit.
The TK sensor placed in boiler pocket (from production), sensors TV and TS (boiler
accessory from 1.3.2019) on the accumulation tank, all connected directly to the burner. The
(2x AD03) modules are inserted under the instrument hood of the boiler and is connected
to the terminal board of the boiler. Both AD03 modules control the exhaust fan of the boiler
and the pump in the boiler circuit.
Boilers version 2016 has only one module AD02 to control exhaust fan.
Required accessories (not part of the burner): nothing needs to be bought
For boilers version 2016 is necesary to buy two KTF 20 sensors (TV and TS sensores)
System configuration of parameters: S6 = 4, S14 = 13, S15 = 2
(reserve R - parameter S6 controls the boiler fan, reserve R2 - parameter S14 controls the boiler pump)
WA R N I NG – for boilers DCxxSP(X)/(EP), CxxSP, ACxxSP, KCxxSP and boilers with
a burner built in the upper doors, it is not possible to use the function of controlling solar
heating directly from the pellet burner.
