Honeywell Home AC112-01/U Temperature Sensor for Radiant Floors

Optimize radiant floor performance and energy use with the Honeywell Home AC112-01/U temperature sensor. Designed specifically for in-floor sensing, this temperature sensor delivers accurate, repeatable readings so your thermostats and controls can maintain safe, comfortable surface temperatures and efficient operation. The AC112-01/U uses a 10 kΩ thermistor (at 25 C) and a thin-profile probe (0.16" x 0.23") that mounts neatly between two heating cables, minimizing installation effort and avoiding hot-spot errors.

With a 10' (3 m) cable and direct compatibility with Aube TH114 and TH115 thermostats, the sensor integrates quickly into residential and commercial radiant heating installations. Beyond HVAC, its reliable environmental monitoring supports smart-building and security platforms that track temperature as part of overall surveillance and facility monitoring strategies. Built by Honeywell Home (Resideo), the AC112-01/U is a practical choice for contractors, facility managers, and integrators who need precise floor temperature control. Order the AC112-01/U today to streamline radiant floor installs and improve system reliability and comfort.
