How do I find the model of my Honeywell thermostat?

Flip the thermostat itself over and look for the model number, which should be printed somewhere on the back of the case. Thermostat model numbers all begin with T,” “TH,” “RTH” “C,” or “CT.” Oftentimes, there will be a “Y” in front of the model number.

Besides, where do I find my Honeywell model number?

For most thermostats, the Model Number is located on the back of the detachable face plate. You can also find this on your product packaging, as well as included literature. If you’re registering a warranty or rebate for a Wi-Fi product, use the MAC ID as your Serial Number.

Likewise, why is my Honeywell thermostat not working? A Honeywell thermostat may be malfunctioning generally, and this is the cause of its inability to hold temperature. If your screen is blank and unresponsive, or flashing, it may mean your thermostat’s batteries are dying. Dirt or debris within the thermostat can also cause problems.
