2 Stage Thermostat Wiring Diagram Image Honeywell, Furnace To Heil 1024×904 - With so many new functions on these days’s thermostats (t-stats), there are many more wires to attach up whilst putting in a brand new or substitute t-stat. Gone are the 2-wire days.? in the ones instances, all you needed became one cord from the furnace transformer.? plus, you had another to feed energy to a fuel valve or relay to turn the warmth on and off.
