CONTROLS WITH ADJUSTABLE DIFFERENTIAL
The movable indicator points to the temperature at which the contacts open. The fixed indicator points to the tem- perature at which the contacts close. The difference between these two indicators is the differential.

1.Use a screwdriver in the adjusting slot (A) on the front of the control to turn the dial so that the fixed indicator
(B) points to the temperature at which the contacts will close.
2.Turn the differential adjusting screw (C) until the movable indicator (D) points to the temperature at which the contacts will open.
