Innovative FusionAir Smart Sensor enhances building occupant experience, increases energy efficiency, and offers safe indoor air quality. The mobile app provides a remote mirroring experience to all FusionAir functions so that changes can be made without a need to touch the sensor, and can be used with a display less model.
