Wyze Thermostat Emergency Heat: How And When To Use It? - Best Smart Thermostat (2024)

The Wyze thermostat doesn’t show the emergency heat activation sign on the thermostat’s display. As a result, many users get confused if the EM option is turned on or not. Also, as a beginner, it is tough to understand the procedure of activating the EM in Wyze thermostats.

So, how and when to use Wyze thermostat emergency heat?

Wyze has an emergency heat option that you can only turn on manually. To activate it, first, you have to connect the backup heating source to the * terminal of the thermostat. After that, when you need the EM feature, you can turn it on from your Wyze App. You should only use the EM feature when your heat pump is unable to warm up the home due to extreme weather or malfunction.

Does Wyze Thermostat Have Emergency Heat?

Wyze Thermostat Emergency Heat: How And When To Use It? - Best Smart Thermostat (1)

Yes, the Wyze thermostat does have the emergency heat feature. In emergency heat mode, the thermostat will bypass the heat pump and use the backup heating source to heat your home.

However, as it’s not efficient to use the emergency heat mode for a long time, the Wyze thermostat also has the aux heating feature. Auxiliary heat is designed to supplement the heat pump’s primary heating mode when the demand for heat exceeds its capacity.

This mode will automatically turn on the backup heating source when necessary to maintain the target temperature. You need to preset which mode you want to go for.

Like these two features, the Wyze safety delay is another great feature of the thermostat you will find very convenient.

How To Turn On The Emergency Heat Wyze Thermostat?

In the Wyze thermostat, the emergency mode has to be turned on manually. So, don’t worry about the emergency mode turning on frequently and raising your electric bill.

For enabling the emergency heat on Wyze, there are two phases.

Phase 1:

This phase will occur during the thermostat’s setup process. Connect the backup heating source to the * terminal. Without performing this setup phase, you can’t be able to activate the emergency heat mode.

Phase 2:

This is the phase where you turn on the emergency mode as necessary. Here’s what you have to do.

Step 1: Open the Wyze App on your smartphone.

Step 2: Go to the “Settings” option in the Wyze App.

Step 3: Select the “Advanced” settings.

Step 4: Keep scrolling and find the “Advanced” section and select “Emergency Heat”.

Step 5: Toggle the “Emergency Heat” switch to the on position.

The thermostat will now activate the backup heating source connected to the * terminal and use it as emergency heat to raise the temperature of your home.

When Should I Use Emergency Heat On My Thermostat?

Emergency heat should be used only in two situations. Emergency heat is intended to be used only as a backup of your heating source if the heat pump is not working. Meanwhile, troubleshoot and fix the heat pump as soon as possible.

You can also use it when there is extremely cold temperature and the heat pump is unable to keep up. Other than these two situations, you have to use the regular heat pump to warm up your house.

Is It Ok To Run The Heat Pump On Emergency Heat?

It is normally not recommended to run a heat pump on emergency heat for a long period of time. Using the emergency heat feature has two primary disadvantages.

High Electricity Bills:

When the heat pump is running on emergency heat, it uses the backup heating source, which is typically an electric resistance heater. Electric resistance heaters are less efficient and more costly to operate than heat pumps. So running the heat pump on emergency heat can result in higher energy bills.

Excess Pressure On The System:

Running the heat pump on emergency heat for an extended period of time can cause damage to the system. It forces the system to bypass the heating pump and work which puts unnecessary stress on the system. As the thermostat starts showing problems, you will see symptoms like your Wyze thermostat clicking. Eventually, the system will collapse leading to a costly repair.
