Description
Overview
The Pro1 IAQ R250S is a wired temperature sensor that can be mounted outdoors or set in a floor slab. Paired with a compatible Pro1 thermostat, such as the T855 series, it lets the thermostat display the outdoor temperature or control radiant floor heat by slab temperature.
It is a small, durable probe on a lead wire that connects to the thermostat sensor terminals. Contractors use it on radiant floor jobs to keep floors from overheating, and on heat pump installs where outdoor temperature helps decide when auxiliary heat should take over.
