Controlling a Single Stage AC with a 2 Stage Thermostat

wstempleOctober 28, 2012

I just got a new 2 stage furnace.Updated the Thermostat wiring to 7 conductor and bought a Pro1 T715 Multi-Stage stat prematurely. Seems like the stat will ONLY work with a 2-Stage AC. Is there any way to wire this to my unit, or do I need to buy another stat?

I think you can. Connect the AC to the Y2 connection and change the swing setting to 0.4 degrees. The second stage AC (Y2) will activate at twice the swing setting which would be 0.8 degrees. If the set point is 75 degrees, then the AC will turn on at 75.8 degrees, and turn off at 74.2 degrees.
