The cooling differential setting is
adjustable from ± 0.2°F to ± 2°F.
For example: A differential setting
of 0.5°F will turn the cooling on
at approximately 0.5°F above the
setpoint and turn the cooling off
at approximately 0.5°F below the
setpoint.
The heating differential setting is
adjustable from ±0.2°F to ± 2°F.
For example: A differential setting
of 0.5°F will turn the heating on
at approximately 0.5°F below
the setpoint and turn the heating
off at approximately 0.5°F above the
