How to Fix / Troubleshooting

Safety: Do not pry aggressively on the display; it can crack.

Steps:

  • Attempt a soft reboot using any available reset option in the app or by holding the power/menu button combination described in the manual.
  • If the thermostat is powered from 24 VAC only, remove it from the wall for 30 seconds to fully power it down, then reattach.
  • If touch remains unresponsive but the display shows normal information, the touch panel or button contacts may be damaged; inspect for cracks or moisture ingress.
  • Check that the display module is fully seated on the wall plate or connector pins.
  • If reseating does not restore function, the display/touch assembly must be replaced (usually by replacing the entire thermostat head unit).
