Honeywell Thermostats are great for controlling your heating system and managing your energy consumption. However every now and then, it may be necessary to reset the device, such as if the power fails, the Wi-Fi network changes or programmable schedule becomes unwieldy.

Below we break out step by step guides on the most popular Honeywell models.

Once reset, make sure to program it the way you like, as the factory default settings may not be suitable for your home.

Where the instructions require you to remove the thermostat from it’s base plate, potentially exposing live wiring, we recommend you isolate the circuit beforehand. 

At SmartHomePerfected we always advise readers not to undertake any work they are not competent in performing and if in any doubt, it is best to seek the assistance of a professional.

How to find the Model Number

Before you learn how to reset your Honeywell Thermostat, you need to know the model you have.

Generally speaking, the model number of your thermostat is either referenced on the front of the device, is accessible through the digital interface or is printed on a label at the back.

In the guide below, we have included images of Honeywell Thermostats within each range to make it easy to identify the correct one.

Make sure to take note of the various settings on the device before resetting, as you may need to reconfigure them.

Below are steps to perform, if you need to remove the thermostat from the base plate to access the model number.

If the model number is not covered by this guide, you can search for the user manual on the following link.

  1. If the thermostat is mains powered, isolate the circuit to avoid exposure to live wiring. (Once the power is off, the thermostat may still be on as some models have a battery backup)
  2. Carefully slide / pull the thermostat off the base plate, making sure not to damage the pins or clips. In some models, this is accomplished by pulling from the bottom of the device.
  3. Take note of the model number at the back and find the corresponding instructions below.
  4. Reposition the thermostat back on to the base plate
