Terry,
I appreciate the feedback. I believe the issue you’re experiencing is due to an older version of the touchscreen beta software. Control firmware version 0.5.65 supports the precision required for displaying temperatures in Celsius. Celsius temperatures are reported with three digits, including a decimal point. What you’re seeing as “720” is Fahrenheit being displayed in the Celsius format without the decimal point.
Support for proper Celsius formatting was added in a newer beta version of the touchscreen software.
Can you please confirm the software version currently running on your touchscreen? The latest beta release is 0.13.040. You can check this on the About page of the touchscreen.
Depending on the version you’re running, the update method may vary. If you’re on an older version, you’ll need to ensure the touchscreen is connected to a network with internet access. Then, tap the time/date on the home screen. This will take you to the Installer Settings page, where you should see an update banner at the top. After 0.13.040 the installer settings page is in the menu.
If you’re unable to access the Installer Settings page or the update isn’t showing, please share the touchscreen version and serial numbers with me and I can confirm.
Thanks,
Mike
