You should be able to check the manual that comes with the inside unit and select a thermostat using that.
Two stage air conditioner thermostats.
For use with a fireplace floor or wall furnace.
Works with direct line voltage.
From my experience this is typically set up during the initial installation.
When the thermostat first turns the unit on only the first stage heating or cooling components run unless the second stage components are needed to maintain a desired temperature.
For heating or cooling units that have a high and low speed.
Two stage thermostats run two stage air handling systems which heat and cool in two phases.
There are ways you can check what both the type of system you have and how many stages it is but this usually involves taking a look inside your current thermostat.
Two stage units don t run as continuously as a variable speed ac but they do cycle on and off less frequently than single stage systems.
