Honeywell Thermostat Instructions Wire Terminals Functions Color Code Furnace And Ac Heat Pump
Honeywell Thermostat Instructions Wire Terminals Functions Co In this hvac training video, i show honeywell thermostat wire terminals, functions, color code , and overall instructions for use! supervision is needed by a. 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.
Honeywell Thermostat Wiring Color Code Honeywell 1st stage heat pump with auxiliary emergency heat (7 wire) this is also known as a 7 wire honeywell thermostat wiring. a first stage heat pump system will have 1 compressor hence only 1 y wire. this is the wire that controls the first stage compressor relay. in addition to the ob wire and r wires, you will have an aux e wire. G – green: fan – this is for the blower in the air handler. r – red: 24 volt power – your air handler is powered by 110v, but it is converted to 24v for the thermostat. c – blue: common wire for continuous 24 volt power from the thermostat to the air handler. e – white (optional): emergency heat. Here are the usual 4 wire thermostat wire color codes for a heat pump: red wire. this is the 24v hot wire that provides power. white wire. this is the heating wire, primarily used to turn on the heating mode of a heat pump. yellow wire. this is the cooling wire, primarily used to turn on the cooling mode of a heat pump. green wire. 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.
