First Stage Differential
First stage temperature differential determines the
sensitivity of the thermostat. A lower differential
will cause the thermostat to cycle more often with
smaller temperature swings.
If the temperature differential between indoor
temperature and setpoint temperature is greater
than the first stage temperature differential, first
stage heating or cooling will be activated.

Second Stage Differential
Second stage temperature differential
determines when the equipment advances from
first to second stage. If the temperature
differential between indoor temperature and
setpoint exceeds the second stage temperature
differential, the equipment activates second
stage heating or cooling.
Press the

Third stage temperature differential determines
when the equipment advances from second to
third stage. Setting the differential temperatures
the same for second stage and third stage turns
second and third stage on at the same time.
Press the

temperature differential. The third stage
temperature differential cannot be set below the
second stage differential.

The Staging Override Time will turn on the next
stage even though the temperature differential has
not been reached.
