How To Install Honeywell Thermostat With Only 2 Wires

By | July 23, 2022



One of the most important tasks for homeowners is to keep their home comfortable regardless of the weather outside. To make this possible, a thermostat is essential. The Honeywell thermostat is one of the leading products on the market due its reliability and convenience. Installing one with only two wires is an easy process that anyone can do with basic knowledge about electronics and tools.

The first step in installing your Honeywell thermostat with just two wires is to shut off the power source for the circuit you’ll be working with. This will eliminate any danger of electrocution. Once the power is off, remove the cover from the existing thermostat to expose the wiring. Take a picture or write down the connections, in case there’s a need to refer back to it later. With all the wires disconnected, you’re ready to start installation of your Honeywell thermostat.

The most important thing to remember when connecting your two-wire Honeywell thermostat is to only connect the two wires to the thermostat. The red wire should be connected to the “R” terminal, while the white wire will be connected to the “W” terminal. Also, be sure all wire connections are tight and secure. Once all the connections have been made, reinstall the cover plate and turn the power back on. That’s it! With the power running, check to make sure the thermostat is working properly. If everything is functioning correctly, you’re done and ready to enjoy the convenience of your new Honeywell thermostat!
