Actually I would recommend one additional step first, update the firmware on the panel. Currently you are on 4.1.1. To get to the latest you would need 4.2.1 first, then you can go to 4.3.0.
Does that help this issue? (I would not expect this alone would fix it, but it is an easier first test)
Then, in the interest of only removing and re-adding once, if firmware alone does not resolve the issue, a factory reset, remove and relearn should be done.
To factory reset:
- Put the thermostat into Off mode. When the thermostat is in Off mode, no symbols are lit below the temperature display.
- Once in Off mode, press and hold the up arrow on the Smart Thermostat until a version displays. The version number does not matter for this process.
- Once the version displays, press and hold the down arrow on the Smart Thermostat until RST displays on the thermostat.
- When RST clears from the thermostat display, the thermostat is reset to factory default configurations.
