How to Fix / Troubleshooting
Safety first: Work only on the thermostat; avoid opening sealed casings if under warranty.
- Reboot device: Remove power/batteries for 1–2 minutes, then restore. This often clears frozen UI states.
- Clean surface: Wipe the screen or buttons with a soft, slightly damp cloth. Do not use solvents or excessive moisture.
- Check for physical damage: Look for cracks or impact marks on the screen. Physical damage usually requires replacement.
- Use app as workaround: If the app still controls the system, use it temporarily and arrange thermostat replacement.
