To remove your old thermostat and replace it with the Honeywell RTH5160 Non-Programmable Thermostat, follow these steps:
1. Turn off the power: Before starting the removal process, turn off the power at the breaker box or switch that controls your heating/cooling system.
2. Check that your system is off: Change the temperature on your old thermostat to be above room temperature in heat mode or below it in cool mode. If you don't hear the system turn on within 5 minutes, the power is off.
3. Remove the old thermostat's faceplate: On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
4. Check for 120/240V wires: Make sure there are no thick black wires with wire nuts. If you have these wires or if your thermostat is 120V or higher, you have a line voltage system and the Honeywell RTH5160 thermostat will not work.
5. Take a picture of your wiring: Before disconnecting any wires, take a picture of how your wiring looks right now. Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your new thermostat.
6. Disconnect the wires and remove the old wall plate: Use a screwdriver to release wires from terminals. Then, use a wire label to identify each wire as it's disconnected. The letter on the wire label should match the letter on the terminal. To prevent wires from falling back into the wall, wrap the wires around a pencil.
Once you have successfully removed your old thermostat, you can proceed with the installation of the Honeywell RTH5160 Non-Programmable Thermostat following the instructions provided in the manual.
