has been set to ON.

dehumidify functionality.

dehumidify functionality. In this setup the fan will run at very low speed because a
Y/Y2 or Y1/W2 is present but the G signal is not. The fan output (G) will be
energized any time the compressor is energized in response to a cooling demand.

On --Three stages of electric heat will be staged.
This switch should be set to On if the HVAC equipment has two banks of strip
heaters. When electric heat is required, the thermostat will energize the smallest
bank first (W1 only), then the larger bank (turning the smaller bank off -- Y1/W2
only), and then both banks together (both W1 and Y1/W2). When power is cycled
to the thermostat, this unit configuration will be displayed as HS.
