Honeywell Thermostat Wiring 4 Wires A round t stat wiring example. the next t stat, the honeywell t8775c1005 (2) non programmable t stat can control both heating and cooling, as well as manual fan operation, with just four wires. this t stat also needs no c wire. for this one, the red wire would attach to the r screw. the green goes to the g screw. If you have a c wire, place it into the c terminal on your wall plate. c wire adapters are available here. let’s look at the g wire. this wire goes to the g terminal on your new thermostat. of the y, y1, and y2 wires, y or y1 go to the y terminal and y2 to the y2 terminal. the o b wire can have many configurations.
How To Wire A Honeywell Thermostat With 4 Wires Tom S Tek Stop Step 1: turn off the hvac system power at the circuit breaker or fuse box. step 2: remove the old thermostat cover and safely disconnect the wires. step 3: capture a photo or create a wiring diagram for reference. step 4: identify wire functions (e.g., red for power, white for heat). step 5: connect wires to corresponding terminals on the new. Using 4 wire thermostat wiring is common for systems with basic heating and cooling, usually a system with a gas furnace indoors and a condensing unit ac outdoors. nest thermostats also use 4 wires along with ecobee, some honeywell models and other smart thermostats. 4 wire thermostat wire color code. the most common 4 wire color code is:. Unscrew the two wires from the terminals. remove the motherboard of the old 2 wire thermostat and put the new 2 wire thermostat in its place. reconnect the red and white wire, tighten down the set screw, and put the control panel back on. test the 2 wire thermostat wiring by turning the furnace on. Honeywell thermostat wiring diagram 4 wire examples. the table above provides a more complete list of honeywell thermostat wiring colors and their uses. but here is a list of the most common wire color mappings, as seen in many four wire t stat setups. c – 24 vac common (you might see blue, purple, or brown typically used for this wire).
