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.
To set the control:
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.
