Setting the anti-cycling device
This appliance is equipped with a potentiometer which delays the ignition of
the heating control and is situated on the P.C.B. (see the electrical diagrams).
By adjusting the potentiometer, it is possible to change the time interval
between the burner shutting down and its next ignition.
It is preset at 1 minute and can be adjusted from 0 to 2 minutes.
Use this control in particular situations where continuous shutting down and
ignition of the main burner occurs.
