This return air sensor provides crucial backup control for HVAC systems equipped with non-zoned RedLINK® wireless thermostats. It is designed to mount on the return air duct to monitor and maintain temperature security.In the event the primary thermostat loses power, this sensor automatically takes over, activating the equipment to ensure the space remains within a safe temperature range until power to the main thermostat is restored.
