Wireless Sensor HONEYWELL RedLINK Outdoor C7089R1013/U | Montreal, Laval, Longueuil, South Shore & North Shore

Adding an outdoor sensor to an existing system often poses a practical challenge: a wire has to be run from the thermostat to the outside wall, through finished walls. The Honeywell RedLINK C7089R1013/U wireless outdoor sensor avoids that work. It measures outdoor temperature and humidity and sends them over RedLINK to the compatible thermostat or equipment, with no wires at all.

Why measure outdoors

The outdoor temperature is valuable data for a heating and cooling system. It shows on the thermostat, which is handy day to day, but it's mostly used for control. With a heat pump and a furnace in a dual energy setup, compatible thermostats can use this reading to choose the heat source. With a humidifier, outdoor temperature and humidity make it possible to adjust indoor humidity to limit condensation on the windows during deep cold spells.

Built for our climate

The sensor operates from -40 to 60 °C, which covers January nights as well as July heat waves. It runs on two lithium AA batteries, included. A low battery warning appears about two months ahead, which leaves plenty of time to replace them. Its wireless communication is designed not to interfere with other wireless devices in the home.

Compatibility: classic RedLINK

The C7089R1013/U belongs to the classic RedLINK generation. It works with RedLINK thermostats and accessories, including the VisionPRO 8000 RedLINK, the Prestige and TrueZONE panels equipped with the wireless adapter. It isn't meant for RedLINK 3.0 thermostats (T10+ Pro, ElitePRO), which use the C7089R3013/U outdoor sensor, identical in appearance. We always check your thermostat's generation before choosing.

Installation by AirGreen

The sensor mounts vertically with the supplied bracket. With no wire to run, installation is quick, and the attention goes to the location:

1. a shaded exterior wall, ideally facing north;
2. away from the heat pump's outdoor unit, exhaust vents and heat sources;
3. out of reach of snow buildup and snow clearing;
4. at a distance that allows good communication with the thermostat.

Once it's mounted, we pair the sensor with the thermostat, check the reading and, if your system is dual energy, configure the settings that use the outdoor temperature.

Wireless really comes into its own in finished homes, townhouse-style condos and brick-clad buildings, where drilling a path for an outdoor wire means finishing work. With this sensor, the job is limited to mounting the bracket and configuring the thermostat, with no trace left indoors.

Savings and comfort

With dual energy, an accurate outdoor reading lets the heat pump work as long as it's the most appropriate source, then hand over to the furnace. With a humidifier, it helps keep indoor air comfortable without water running down the windows. The wireless sensor offers these benefits without any finishing work.

Maintenance

Replace the lithium batteries when the warning appears. In spring, check that the bracket is still solid and that nothing is covering the sensor.
