With the touch of a button, the Wyze thermostat controls your home’s interior temperature. Whether it’s too hot or too cold, you can make the desired changes as needed by using the Wyze app. The app works with various appliances, including your home’s air conditioner, hydronic systems, and other related devices. But does the Wyze thermostat and app work with heat pumps too?

The Wyze thermostat works with low-voltage heat pumps, ideally those in a 24-volt system. Generally speaking, the thermostat works with most single-stage and multi-stage heat pump systems.

Continue reading to learn more about connecting your Wyze thermostat to your heat pump and determining compatibility.  

Which Heat Pumps Does the Wyze Thermostat Work with?

Wyze does not work with high-voltage devices. So, before doing anything else, look at the specs on your heat pump. If it has a warning label saying that its voltage is 110 or higher, you can’t use the thermostat with it. Additionally, if you see the labels “L1” or “L2” on your heating system, again, do not proceed.

If none of these signs are evident, then you can move forward with the installation process.

How to Connect Wyze Thermostat to Heat Pump

During the installation process, your safety is your top priority. Before doing anything else, turn off your HVAC system’s power. You can do this by locating your fuse box and turning off the breaker that supplies power to these components.

If you’re not sure how to do this, turn off the power to your entire home. Installation only takes 30 minutes, so you’ll only need to be without electricity for this duration.  

Remove the Jumper Wire

Now, this is the part where you’ll connect your thermostat to your home’s wiring grid. You might want to take a picture of your setup before removing anything, as you may need this information later on.

At this stage, remove your old thermostat’s cover and unscrew the jumper wire. You can do this by unscrewing the screw beneath it with a Phillips flathead screwdriver.

Identify Your Wiring Components

Now it’s time to whip out the Wyze app. You can download it through the Apple App Store or Google Play Store. Navigate to the setup menu and from the “preparation” window and choose the terminals with wires connected. For instance, your wires might have letters or numbers beneath them. Mark these symbols in the app.

Note: At this stage, you may need to add a “C-wire” if your setup doesn’t have one. You can learn more about that process by watching this video.

Remove Your Old Thermostat

Your Wyze setup kit will come with blue sticker tabs. Use these stickers to indicate your already-existing wires’ letters. Keep in mind that the stickers may not be exact. So, for instance, if a wire is labeled as Y1, you can use the Y sticker. If they don’t match up, it doesn’t really matter; this just for your reference later on.

Then, using the Philips flathead, remove your old thermostat’s cover from the wall. When you’re done, you should only see the exposed wires coming from the wall.

Screw the Backplate onto the Wall

Your Wyze thermostat’s black plate will have a hole in the middle. Thread the wires through this hole, and screw the backplate onto the wall. During this process, make sure that the wires do not fall back into the wall, as this will complicate installation.

If you have plaster or concrete walls, you may need to drill a new hole into the wall and use the anchors that came with your purchase.

Connect Your Wires

Once you’ve screwed in the back panel, you’ll need to match up the wires with the appropriate slot in the grey rectangular box.The wires’ copper part goes through the slot directly beneath it—not the port facing outward. When the wire is secured, the lever above it will stay down.

Attach Your Wyze Thermostat

Once you’ve completed the above steps, snap the Wyze thermostat’s face into place. You shouldn’t have to force it in place. If you find that it’s crooked or loose, it may not be secure.

At this point, you can go through the app to complete the software aspect of the installation process. Be sure to turn on your HVAC system or home’s main breaker to move on.

If you successfully complete this installation process, then your Wyze thermostat should automatically work with your heat pump, as well as other aspects of your home’s climate regulation system.

In Conclusion

Your Wyze thermostat should work with most heat pumps. However, if your heat pump exceeds a specific voltage, it may not be compatible with the device. Be sure to read your HVAC system’s specifications before purchase or installation to confirm compatibility.
