Thermostat time and date keep resetting after power interruptions.

Safety first: No high-voltage work is required.

• Step 1 – Connect to Wi‑Fi: Ensure the thermostat is connected to the internet so it can automatically sync time.
• Step 2 – Check for firmware updates: Update thermostat firmware to the latest version.
• Step 3 – Manually set time: Set the correct time and date in the thermostat settings and monitor for resets.
• Step 4 – Replace thermostat: If time resets persist without power loss, the internal clock or backup power circuit may be defective.
