Thermostat buttons or touch screen intermittently unresponsive

Safety first: Do not open the thermostat while powered unless qualified.

Steps:

• Clean the front of the thermostat with a dry, soft cloth; avoid liquids or sprays.
• Check supply voltage for stability; rectify any loose connections or low voltage issues.
• Power cycle the thermostat and test button/touch response again.
• If unresponsiveness persists or worsens, replace the thermostat as the touch controller or front panel is likely failing.
