Thermostat or wall area feels unusually warm to the touch

Safety first: Do not open the thermostat housing beyond manufacturer instructions; internal components are delicate.

Steps to troubleshoot:

• 1. Reduce backlight: Lower the display brightness and backlight timeout in thermostat settings.
• 2. Check for wall drafts: Remove the thermostat and feel for warm air from the wall cavity. Seal large openings with non-flammable insulation.
• 3. Verify mounting: Ensure the thermostat is mounted on a standard wall plate and not directly over a heat source or duct.
• 4. Monitor temperature reading: If the thermostat reads significantly higher than room temperature, adjust calibration or relocate if necessary.

When to call a professional: If the thermostat becomes hot to the touch or emits a burning smell, power down the HVAC system and replace the thermostat immediately.
