Inputs
The board power supply is connected to the L and N clamps of the X4 connector.
- 230 V AC +10% / -15%

- 50 Hz +/- 5%

Detects the ignition of the burner by which the flame is hit and
allows the integrated P.C.B. to increase fan speed after having limited
it during the ignition phase.
It is connected to the detection circuit of the integrated P.C.B.
Outputs
It is controlled by the integrated P.C.B. when burner ignition is requested.
It makes the ignition spark.
It is positioned on the condensation module.
They are controlled by the igniter that causes an electric spark between their ends and on
the contact with which the air-gas mix ignites.
It is powered by the integrated P.C.B. when there is a DHW, CH or anti-freeze request.
Allows circulation in the primary circuit.
It is powered by the integrated P.C.B. when there are conditions for activation of the solar
circuit (see solar circuit functioning).
Allows circulation in the solar circuit.
It is powered by the integrated P.C.B. when there is a CH or anti-freeze request.
Allows circulation in the CH system.
The board is always powered independently from the position of the
P.C.B. functioning).
Allows to power the CH pump (M2).
It is powered via the CH contact of the 3-way valve.
It allows the diversion of the water flow of the primary circuit to the storage tank coil and
vice versa.
It is powered by the integrated P.C.B.
Safety devices
It is a filter connected to the power supply line of the pump relay board, which allows to
limit the effects of electromagnetic interference.
It cuts off the power supply to the circuit when the current absorbed
exceeds 3.15A.
It is inserted onto the integrated P.C.B.
