valve
The electric circuit is interlocked with a microprocessor electronic board that controls boiler functions.
The control and safety devices work in part at mains voltage and in part at low voltage.
230 V AC CIRCUIT
SAFETY DEVICES AND CONTROLS
Detection electrode (E3)
This detects ignition of the burner by whose flame it is invested.
It is connected to the detection circuit of the ignition unit.
Fuse
This interrupts power to the circuit when amp draw is over 3.15 A.
It is fitted on the modulation board.
Fuse
