Thermostat question
Greetings,
I recently purchased a new Trane two-stage furnace and air conditioner. I still have the old, non-electronic, non-programmable thermostat that I have had for years (with my previous single-stage furnace). The HVAC contractor said that it would be wise (but not required) to get a programmable thermostat. His company actually sells/installs them, but he said that I could save a lot of money by doing it myself. As I've started looking into this, I'm a little confused about whether to install a single-stage or two-stage thermostat. I understand that if I get a single-stage thermostat, then the furnace will start up with the first stage and go to full heat after 10-15 minutes. With a two-stage thermostat, the thermostat apparently has control over the starting and stopping of these stages. Is that right? My existing thermostat has four wires coming into it. I assume that I'd have to run more wire to use a two-stage thermostat. Is that right? That would be somewhat of a pain, so I'm trying to gauge the benefit of doing that vs going with a single-stage (but still programmable) thermostat. Any advice appreciated. |
