Thermostat buttons or touchscreen are unresponsive or respond intermittently

Safety: Turn off power at the breaker before removing the thermostat if needed.

Steps to restore UI responsiveness:

• 1. Clean surface: Gently clean the thermostat front with a soft, dry microfiber cloth. Remove any oily residue or dirt.
• 2. Avoid gloves: Use bare fingers when touching the screen; some gloves block capacitive sensing.
• 3. Power cycle: Turn the breaker OFF for 1 minute, then ON. Test the buttons/touch again.
• 4. Check for warping: Ensure the thermostat is mounted flat against the wall and not twisted, which can stress the touch panel.
• 5. Reseat front panel (advanced): With power OFF, remove the thermostat and reseat any connectors between the front panel and main board.
• 6. Use app as workaround: Control the thermostat via the Stelpro app if the local UI is unreliable.
• 7. Replace thermostat: If the UI remains unresponsive, replace the thermostat.

Note: Avoid using harsh chemicals on the touch surface; they can damage the sensor.
