Old to New Thermostat Wiring - A Guide to Replacing Your Existing Unit

Switching from an old thermostat to a new one is a great way to upgrade your home and save on energy costs. It's also a project that requires careful consideration when planning, both for safety purposes and for providing the best results in terms of comfort and cost savings. To make sure you're doing everything correctly, here's a guide on how to replace your existing thermostat with a new one.

Who Should Replace Your Thermostat?

Before you begin the process of replacing your old thermostat with a newer, more efficient one, you should consult a professional. While it may seem straightforward, there are many moving parts and potential problems that could arise when dealing with electrical wiring. A heating and cooling specialist can provide you with advice on which type of thermostat is right for your specific needs, as well as certified installation of your new unit. This will ensure both proper performance and safety standards are met.

What Are The Steps To Replacing Your Old Thermostat?

Once you've decided to upgrade your thermostat—and you've consulted a professional if necessary—the next step is to gather the necessary supplies. Before beginning work, you'll need to turn off the power to the thermostat and label the wires. This will not only help you keep track of what goes where, but it will also ensure that you don't get confused during the process.

Tools: You'll need standard tools, such as a screwdriver, wire cutters, and electrical tape.

Replacement Thermostat: Make sure to buy the correct model for your needs.

Replacement Wiring: If necessary, purchase additional wiring in order to properly connect the new unit.

Mounting Plate: This might be included with the replacement thermostat, or you may need to buy it separately.

Take Care Of Wiring Before Installation

Now it's time to prepare the wiring for the new thermostat. Be sure to use the same colored wires for the same labeled functions (e.g., red for G, white for W). If there's any additional wiring needed, simply add it in along the same path as the original. Once all of the wiring is set, secure it tightly to the wall and place the mounting plate onto the wall as directed by the instructions.

Install The New Thermostat

Now you can mount the new thermostat onto the mounting plate. Connect all of the wires to their designated terminals, then secure the thermostat in place with the screws provided. If the installation is done correctly, you should be able to switch the breaker back on without any issues. To test the functionality of the new thermostat, adjust the settings and observe the results.

Conclusion

Replacing an old thermostat with a new one is a great way to upgrade your home, save money, and improve your comfort. Following the above steps will help you successfully complete the process and ensure the best results. Just remember to consult a professional if necessary and never hesitate to ask for advice when dealing with electrical wiring.
