Wireless Sensor HONEYWELL RedLINK 3.0 Outdoor C7089R3013/U | Montreal, Laval, Longueuil, South Shore & North Shore

You have a T10+ Pro or ElitePRO thermostat and a central heat pump paired with a furnace. For that pair to work at its best in winter, the thermostat needs to know the outdoor temperature. The Honeywell RedLINK 3.0 C7089R3013/U wireless outdoor sensor sends it the outdoor temperature and humidity via RedLINK 3.0 (900 MHz), with no wire to run through the walls.

The outdoor companion for RedLINK 3.0 thermostats

This sensor is part of the RedLINK 3.0 family. It's compatible with the T10+ Pro Smart and with ElitePRO S1000, S1100 and S1200 thermostats. It doesn't pair with older classic RedLINK thermostats, which use the similar-looking C7089R1013/U sensor. If your T10+ Pro kit doesn't include an outdoor sensor, the C7089R3013/U is the natural add-on.

What the outdoor reading is for

The outdoor temperature shows on the thermostat, but its main role is in regulation. In a dual energy home, it lets the system choose when the heat pump hands over to the furnace or backup heat. The outdoor humidity reading adds to the thermostat's information, particularly for managing indoor humidity when the equipment allows it. In Québec, where the gap between an October day and a February night is huge, this data helps the system adapt as the season goes on.

Batteries and battery status

The sensor runs on two AA lithium batteries, included. Battery status shows on the thermostat, and a low-battery warning appears about two months ahead. It operates from -40 to 60 °C and its communication is designed not to interfere with other wireless devices in the home.

Our installation

The sensor mounts on an exterior wall with the supplied hardware. Installation is quick, but the location deserves some thought. Our technicians:

1. choose a shaded wall, out of direct sunlight;
2. keep it away from the outdoor unit, dryer exhausts and vents;
3. place the sensor above the usual snow line;
4. pair it with the T10+ Pro or ElitePRO and check communication;
5. configure the dual energy settings that use the outdoor temperature.

Since the sensor is wireless, no wall needs to be opened, inside or out. That's a real advantage in a finished house, where a wired outdoor sensor would mean drilling through the siding and running through walls that are already painted.

Making better use of the heat pump

A central heat pump heats efficiently for a good part of the Québec winter. With a reliable outdoor reading, the thermostat lets it work as long as it remains the most appropriate source and brings in the furnace at the right time. You get the full benefit of your heat pump investment and limit unnecessary use of backup heat.

During the shoulder seasons, fall and spring, the heat pump can handle almost all the heating on its own. The sensor lets the thermostat recognize that without you having to step in, then call on the furnace when the cold sets in for good.

Maintenance

Replace the batteries when the thermostat signals it. Every spring, check the mounting and remove leaves or debris that have built up around the sensor.
