I bought a new house. 4 thermostats and 3 zones. I bought a
I bought a new house. It has non-wifi thermostats installed in 2011. I would like to install wifi thermostats. 4 thermostats. 3 are Honeywell 2 stage Vision Pro 8000. These are located in basement, on 2nd floor bedroom, and 2nd floor master bedroom. All 3 connect to a Honeywell TrolATemp Universal Minizone attached to a furnace. Notes on the furnace indicate each thermostat is a separate zone. 4th thermostat is a Honeywell IAQ on the 1st floor. It is attached to a Honeywell Equipment Interface Module THM5421C on the second furnace. This thermostat is on the 1st floor and controls that level. None of the thermostats have a C wire. The 3 2 stage Vision Pro 8000s have R, W, Y, G, Y2, W2. The IAQ has 3 wires labelled 1 (red), 2 (white), 3 (green). I would like install wifi thermostats. My first choice would be Google Nest as I have other Google products in the home but swapping the current Honeywell for a wifi Honeywell would be OK. I DO NOT want to screw up my furnace or the zones when doing this. I have read that I can convert a G wire in my current setup to a C wire and then basically install any Nest or Honeywell product to replace the Vision Pro 8000s. Or I can choose the Honeywell T5+ or T9 which don't need a C wire. I am seeking advice as to if making the G wire a C wire and installing a Honeywell RTH9585WF is a good idea? And How to replace the IAQ with a wifi thermostat? … read more
