Technical description of the burner

4.15 Calibration of the thermal relay

The thermal relay serves to avoid damage to the motor due to an
excessive absorption increase or if a phase is missing.
For calibration 

2)

, see the table in the wiring diagram.

To reset, in case of an intervention of the thermal relay, press the
“RESET” button 1) of Fig. 10.
The red “TEST” button 3) opens the NC (95-96) contact and
stops the motor.

CAUTION

The automatic reset can be dangerous. This oper-
ation is not foreseen in the burner operation.

Therefore do not position the “RESET” button
1) on “A”.
