Anonymous What the ****? There is not a way to change it to Fahrenheit?
Hi, thanks for reaching out, and sorry for the frustration.
The ZWT198 thermostat's display works in Celsius only — the device itself doesn't have a Fahrenheit option. However, you can try switching the unit in the Smart Life app: go to Me → Settings → Temperature Unit and select °F. This may show readings in Fahrenheit within the app, though the thermostat screen will stay in Celsius.
If this doesn't work for you, just let us know and we'll be happy to help.
