Resideo c7089r1013/u Outdoor Temp Humidity Sensor

Product Description

The RESIDEO c7089r1013/u is a wireless outdoor temperature and humidity sensor designed for use with RedLINK-enabled thermostats and accessories. The sensor measures both temperature and relative humidity, transmitting readings to compatible thermostats displayed inside the home or building. Operating range spans -40 degrees F to 140 degrees F and 0% to 100% non-condensing relative humidity, making it reliable across a wide range of climates. A thermistor sensing element delivers accurate readings, and the included AAA alkaline batteries support up to 5 years of service life with a 2-month low battery warning under normal use.

This sensor supports outdoor temperature sensing applications including balance point lockouts, frost control for humidity, and smart ventilation lockouts. It mounts vertically on an exterior wall and is suited for residential and light commercial installations where a RedLINK-compatible thermostat system is already in place. The gray housing blends with standard exterior finishes. HVAC technicians and controls installers typically deploy this sensor as part of a broader thermostat and zoning control system.

Installation Notes

Installation is typically performed by a licensed HVAC technician or controls installer. Mount the sensor vertically on an exterior wall in a location that provides accurate ambient air exposure, avoiding areas subject to direct sunlight, exhaust vents, or radiant heat sources. Power down the thermostat system before pairing or configuring accessories per the thermostat manufacturer instructions. Confirm wireless signal strength between the sensor and the thermostat during commissioning before finalizing the mount location.
