Understanding Thermostat Wiring
Before we dive into Honeywell 4 wire thermostat wiring diagram, let’s first understand the basics of thermostat wiring. The wiring of thermostats can get a little complicated, but it is important to understand the wiring to properly install the thermostat. A thermostat has different wires that perform different functions.
The wires are colored and labeled based on their functions. Here’s a brief overview of thermostat wire colors:
| Wire Color | Function |
|---|---|
| Red | Power supply for heating and cooling system |
| Yellow | Controls cooling system |
| Green | Controls fan |
| White | Controls heating system |
Other wires such as black, blue, and orange may be present on some thermostat models, but these wires are not commonly used. Now that we know the basics of thermostat wiring, let’s move on to the Honeywell 4 wire thermostat wiring diagram.
