[Shop-talk] Wiring a Honywell WiFi Thermostat to a 2 wire system

[Rochlin Robert]

	I moved my Honeywell WiFi thermostat from the 1st floor where it controlled A/C, heat, and fan to the garage where it would only control heat. I wired a C wire and connected the red and white wires from the appropriate boiler zone to the WiFi thermostat but I does seem to be getting power. Aside from not having a fan or A/C wire the installation is the same.  I know the C wire is a good circuit because it is the same one that this thermostat used, and a new now functioning first floor thermostat uses. Any help appreciated.
	Best,
