The CHV-RTHS is a wall-mounted remote temperature and relative humidity sensor designed for use with select Crestron® thermostats. Using CAT5 or similar low-capacitance wire, the remote sensor can be mounted up to 500 ft (152 m) from the thermostat. One-piece mounting and a single nonpolarized twisted-pair connection make the CHV-RTHS simple to install. The 1-1/2 in. diameter face protrudes just 1/8 in. from the wall surface and is easily painted or wallpapered to blend into the wall surface.

Use with the MMK-RS (sold separately) to simplify the wiring and sensor positioning during the rough-in stage of construction. The MMK-RS has an option to completely flush mount the sensor and make it virtually hidden on a wall.
