NOTE: The first and second stage differential settings are the same for both the
heating and cooling systems.
Setting First Stage Differential
The default setting is 0.5˚ F (0.25˚ C). The room temperature must change .5˚ F

1. In normal operating mode, press and hold the and
buttons at the same time for 3 seconds. LCD display will
show "SET D1 x˚", where "x" equals the ˚F / ˚C differential
setting. This is the current first stage differential setting.
2. Press the or buttons to set the first stage differential
to your desired setting of .5˚, 1˚, or 2˚ F (.25––displayed as
.3˚, .5˚ or 1.0˚ C).
