Description
The Pro1 IAQ R250S Remote Sensor is a professional-grade wired accessory designed to expand the temperature sensing capabilities of compatible Pro1 IAQ thermostats, including the T755S, T855SH, and T855iSH models. Whether you want accurate outdoor temperature readings to optimize dual-fuel systems or slab (floor) temperature feedback for radiant heating control, the R250S delivers precise performance and durability.
Built to withstand a wide range of conditions with a temperature range from −4°F to 140°F (−20°C to 60°C) and ±1°F accuracy, this remote sensor helps your thermostat make smarter, more responsive HVAC decisions. The wired design with constant resistance transmission ensures dependable connectivity and allows you to relocate the sensing point away from the main thermostat for improved comfort control. Ideal for residential and commercial HVAC installations, the Pro1 IAQ R250S enhances system performance and accuracy when integrated with your Pro1 IAQ thermostat.
