Honeywell Home C7189R1004/U RedLINK®-Enabled Wireless Indoor Air Sensor

The C7189R1004 is a RedLINK-enabled wireless indoor air sensor from Resideo (Honeywell Home).

RedLINK is the wireless link Resideo uses between a thermostat and the rest of the system. Instead of pulling a wire from the equipment to every sensor and module, the devices are enrolled to the thermostat or to a wireless adapter and talk to it directly — which is what makes a sensor in a room with no thermostat wire, or an outdoor sensor with no conduit to the attic, a realistic job rather than a demolition project.

Enrolment is the step that decides whether it works. Each device has to be added to the system at the thermostat or the adapter; a RedLINK device that has not been enrolled is inert, and one enrolled to the wrong system stays enrolled until it is cleared.

A remote indoor sensor fixes the oldest complaint in residential HVAC: the thermostat is in the hallway and the hallway is not where anyone sits. Put a sensor in the room that actually matters and the system controls to that room, with no wire pulled and no thermostat relocated.

Battery life is best between 35 °F to 114 °F, so treat it as indoor equipment — not a garage or an unconditioned attic.
