A smart thermostat is effective in increasing the efficiency of your HVAC system. It can learn your home’s pattern and automatically adjust heating and cooling conditions to increase comfort in your living space. It helps reduce energy bills, and you can control it from anywhere within or out of your home. Nevertheless, you will have to buy and install a thermostat for your HVAC if the current one is dysfunctional. Fortunately, the process is simple. Here is a step-by-step guide to installing a smart thermostat.
1. Acquire a Compatible Smart Thermostat
There is no single universal smart thermostat compatible with all HVAC systems. That said, be sure to look for a suitable thermostat for your system before starting the installation process. The thermostat you select should have voltage requirements that align with your system. Higher or lower voltage thermostats may damage your HVAC unit and result in electric shocks and fire hazards. Consult your manufacturer or look for online checklists to help you select the most suitable thermostat for your unit.
2. Switch Off Your HVAC System
After acquiring a compatible thermostat, switch off the heating and cooling system at the breaker panel. If your system has more than one breaker panel, turn all of them off. Cutting the power supply to your system will protect you from potential electrocution when installing the new smart thermostat.
3. Remove the Faceplate
Detach your thermostat’s faceplate to expose its wires and backplate. The removal should be straightforward. If the faceplate doesn’t pop off easily, look for any hidden screws and unscrew them. Once the faceplate is out of the way, take a picture of the wiring before disconnecting the wires. The photo will help you connect the wires later when installing the new thermostat.
4. Pop Off the Backplate
To remove the backplate, you must first disconnect the wires attached to the backplate with the help of a pen or screwdriver. Proceed to remove the backplate by unscrewing the screws holding it on the wall. Detaching the backplate will expose your thermostat wires.
5. Connect a Connecting Wire if Needed
Not all HVAC systems have a connecting wire (C-Wire). If your unit has one, move to the next step. If it doesn’t, you will have to add one to power your system.
The good news is that there are many options for adding a C-Wire to your unit. One option is using a power extender kit with the thermostat to add a C-Wire on your system’s control board. Many manufacturers and retailers sell the thermostat with the kit.
The second alternative is acquiring a 24-volt adapter and plugging it into an outlet near your thermostat to power it. The final option is installing a C-Wire if your control board has an unused C-Wire terminal. It is advisable to call a professional to help you add the C-Wire if you have any problems.
6. Install the New Thermostat
When installing the new thermostat, begin by mounting its backplate on the wall. Put the backplate against the wall and determine where you will need to drill holes. Pass the thermostat wires through the backplate, then use screws to mount it on the wall.
Proceed to connect the thermostat wires to their respective terminals. Use the photo you took earlier to help you connect the wires. Connect the wires correctly and ensure they are not loose. Tuck them properly inside the backplate to prevent them from bulging.
Cover the connected wires and backplate with the new faceplate. It should easily fit if you mounted the backplate and connected all the wires as required.
7. Complete Thermostat Set Up
Once your new thermostat is in place, turn on the power to your HVAC unit. Use the reset button to reprogram your HVAC unit and smart thermostat based on the manufacturer’s instructions. Connect it to your Wi-Fi to enable you to control it remotely using your smartphone or other connected devices. Test your system to determine if it is working.
