Thermostat randomly changes setpoints or schedules without user input.

Safety first: No electrical work is required.

• Step 1 – Review schedule: Check the thermostat's schedule settings and disable any smart or adaptive scheduling features if undesired.
• Step 2 – Check app and integrations: Review settings in the Carrier app and any connected smart home platforms (e.g., voice assistants) that may be adjusting temperatures.
• Step 3 – Change account access: Ensure only authorized users have access to the thermostat in the app.
• Step 4 – Firmware update: Update thermostat firmware to the latest version to resolve known bugs.
• Step 5 – Factory reset: As a last resort, perform a factory reset and reconfigure the thermostat.
