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.
