Upgrading Digital Thermostat w/ Heat Pump & Gas Aux
Hi,
I am looking for a recommendation for a new thermostat.
I currently have an electric heat pump with gas backup and two-stage blower. The current thermostat is a very basic digital model ( White-Rodgers ) and is working properly, as far as I can tell. It works like this:
Heating Mode: Activates heat pump as normal until it decides (somehow) that it's not working well enough at which point it activates stage 2 which only increases the blower speed. If this is insufficient to heat the home, I have to manually switch it to...
Emergency Heat Mode: Activates gas furnace, ignoring temperature setting, and runs until it feels it needs a break.
Cooling Mode: Unused by me so far, home inspector successfully tested.
Auto-changeover mode: Switches between Heating mode and Cooling mode as needed
The manual that the previous homeowner left me is not the correct manual for this brand & model of thermostat, so it's not too helpful. My model has 8 wire terminals and 6 of them are in use (6 small wires coming out of the wall).
What I am looking for is a model that will switch to the gas furnace backup automatically, or at the very least, mind the temperature setting. It would also be nice to have one that is backlit and programmable. I am not very concerned about price.
With a modern thermostat already connected for reference, I would be comfortable installing this myself. I also have access to a friend in the HVAC business for advice/help if need be.
Thank you for your time!
