and activate the first cooling stage. If the room temperature is 2°C colder than the set point, the
second stage will be activated (2-stage systems only). The second stage is deactivaed when room
temperature is within 1°C of the set point. The first stage is deactivated when room temperature
reaches the set point.
With a heat pump system: the reversing valve is not energized.
