“AUTO” - Auto Change Over Mode
In the
AUTO
mode the system will automatically change the mode of operation from
cool to heat or from heat to cool. In order for this mode to operate, the zone being
programmed must contain either a heat pump, heat strip or furnace heating source.
When in the
AUTO
mode, all pre-programmed operations for the heat pump, heat
strip, and furnace will apply.
Auto Change Over Cooling:
If the room temperature rises above the temperature
set-point by 2 °F / °C, the air conditioner will turn ON until the room temperature
reaches the temperature set-point at which time the air conditioner will cycle OFF.
Auto Change Over Heating:
If the room temperature goes below the temperature
set-point by 2 °F / °C, the available heat source will be cycled ON until the room
temperature reaches the temperature set point at which time it will cycle OFF.
If more than one heat source is available on this zone, the priority for selecting the
heat source will be heat pump (first), furnace (second), and heat strip (third).
