Thermostat touchscreen is slow to respond or occasionally freezes, but eventually recovers

Safety: No high-voltage work is required.

• Reboot thermostat: Turn the HVAC breaker OFF for 1–2 minutes, then ON to reboot the thermostat and clear temporary glitches.
• Reduce load: Disable non-essential features (complex animations, heavy logging, or third-party integrations) if available in settings.
• Check temperature: Ensure the thermostat is not installed in an area that gets excessively hot, which can slow electronics.
• Firmware update: Connect to Wi‑Fi and check for firmware updates that may improve performance.
• Replacement: If freezing becomes frequent or the screen stops responding entirely, replace the thermostat.
