Resideo c7089r3013/u Outdoor Temp Humidity Sensor

Product Description

The RESIDEO c7089r3013/u is a wireless outdoor temperature and humidity sensor designed for use with the RedLINK system. It mounts on an exterior wall and transmits real-time temperature and humidity readings to compatible thermostats inside the structure. Operating across a wide ambient range of -40 degrees F to 140 degrees F, this sensor handles harsh climates without issue. A thermistor-based design delivers accurate environmental readings, and the included AA lithium batteries support up to 5 years of service life. A 2-month low battery warning gives technicians and building operators advance notice before power loss. HVAC technicians and controls installers are the primary trade audience for this device.

The c7089r3013/u is suited for residential and light commercial applications where outdoor conditions feed into thermostat logic. It supports balance point lockouts, frost control for humidity management, and smart ventilation lockouts when paired with a compatible system. The sensor mounts vertically on an exterior wall and connects wirelessly to T10+ thermostats, making it a practical addition to systems where outdoor ambient data drives comfort or energy control decisions. Mounting hardware and batteries are included in the box.

Key Features

• Wireless RedLINK communication eliminates the need for sensor wiring runs to the thermostat
• Measures both outdoor temperature and relative humidity (0% to 100% non-condensing)
• Wide operating range: -40 degrees F to 140 degrees F for reliable performance in any climate
• 5-year battery life with 2-month low battery warning based on normal use
• Supports balance point lockouts, frost control, and smart ventilation lockouts
• Includes 2 AA lithium batteries and mounting hardware

Compatibility

Designed for use with T10+ thermostats as part of the RedLINK wireless sensor 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 reflects true outdoor ambient conditions, away from direct sunlight, exhaust vents, and heat sources. Power down the thermostat system before pairing the sensor according to the thermostat manufacturer's setup procedure. Do not expose the sensor to direct water spray or submerge it, even though it is rated for outdoor ambient humidity up to 100% non-condensing.
