Thermostat time and schedules reset after every power loss or battery change.

Safety first: No special safety concerns beyond normal handling.

Steps:

• Use Ally Gateway: Ensure the thermostat is paired with the Ally Gateway so time and schedules can be synchronized automatically.
• Minimize power interruptions: When changing batteries, do so quickly to reduce the time without power.
• Firmware update: Check for and install firmware updates via the Ally app that may address clock retention issues.
• Replace thermostat: If configuration is lost after even short power interruptions, the internal memory or backup circuit may be faulty; replace the unit.
