20. Connection of boilers DxxPX, PXxx with buffer tank for
regulation of the burner based on sensors TS and TV and
control of boiler pump based on TK sensor
INFO - The TK sensor placed in boiler pocket (from production), TSV waste gas sensor
build in boiler waste gas duct (from production), sensors TV and TS (boiler accessory) on
the buffer tank and all connected directly to the burner. ATMOS A25 pellet burner directly
control exhaust fan of the boiler (R) and pump in boiler circuit (R2). R2 output is connected
in serie with TČ70 °C pump thermostat for pump in boiler circuit.
Required accessories (not part of the burner): nothing needs to be bought
System configuration of parameters:
for boilers D15PX, D20PX, D25PX, PX15, PX20, PX25: S6 = 3, S14 = 12, S15 = 2
for boilers D10PX, PX10: S6 = 0, S14 = 12, S15 = 2
(reserve R - parameter S6 controls directly the boiler fan, reserve R2 - parameter S14 controls directly
the boiler pump)
CAUTION – D10PX, PXxx boilers do not have exhaust fan and R reserve is not used
