Description
The Pro1 IAQ R250S is a professional-grade wired remote temperature sensor engineered to expand the sensing capabilities of compatible Pro1 IAQ thermostats, including the T755S, T855SH, and T855iSH. Whether your application calls for accurate outdoor temperature monitoring to optimize a dual-fuel system or precise slab feedback for radiant heating control, the R250S delivers the reliable performance your installation demands.
Rated for a wide operating range of −4°F to 140°F (−20°C to 60°C) with ±1°F accuracy, this sensor empowers your thermostat to make smarter, more responsive HVAC decisions. Constant resistance transmission ensures a dependable wired connection and allows the sensing point to be relocated away from the main thermostat — improving comfort control and system efficiency. Suitable for both residential and commercial HVAC installations, the R250S is a straightforward upgrade that enhances accuracy and performance across your Pro1 IAQ system.
