Looking for a 4Heat, 2Cool Stage Z-Wave Thermostat

Just in the process of having our upstairs HVAC unit replaced and have settled on a Trane XL16i heat pump system with an XV80 Furnace. Given this, the thermostat being installed is a Trane XL900 4 Heat, 2 Cool (since the Heat pump AND furnace are both two-stage).

I would like to integrate this into my Z-Wave network but ideally need a 4 Heat Stage thermostat.

Haven’t been able to locate one and was checking to see if anyone was aware of any.

It would have to have the EHEAT mode like the Trane Z-Wave so the compressor can be locked out at cold outdoor temps.

I can probably live with just one of the stages for the gas furnace since we don’t usually drop below the teens overnight in the winter.

Thanks.

I use the Trane XL16i heat pump system with AUX electric heat.
I just use the Trane Z-Wave thermostat. The AUX heat is the 3rd stage.
And with EHEAT it’s the 1st stage.

Thanks for the post. In my case, Aux heat involves the Gas furnace which has two stages. The Trane doesn’t have a terminal to connect the 2nd Aux stage to…

I did notice that the 2gig CT-100 supports 4 stage heat (2 heat pump and 2 aux). The apparent things missing on the CT-100 are EHEAT or Compressor lockout for cold temperature and FAN Cycle mode.

The Honeywell Z-Wave thermostat appears to have Cycle and EHEAT mode but not sure if they have 4 HEAT cycles… The search continues…
