The second stage will turn on at 2x the swing setting. The second stage will turn off when 1x the swing is 

reached. For example, if the swing setting is .8 degrees for heating and the thermostat is set at 70ºF, the 

first stage will turn on at approximately 69.2ºF. The second stage will turn on at 68.4ºF. The second stage 

will turn off at 69.2ºF and the first will turn off at 70.8ºF. If third stage is used, it will turn on at 3x the swing 

and turn off at approximately 2x the swing.

Balance Point:

The system operates differently when a balance point is used on a dual fuel system. The balance point 

outdoor temperature setting will be the outdoor temperature at which the thermostat chooses either the 

heat pump or gas furnace. 

For Example:

 A balance point setting of 30ºF will turn on only the heat pump 

above 30ºF and only the gas furnace below 30ºF. 

Y1

 will be stage one above 30ºF and 

W2

 will be stage 

one below 30ºF.
