Reading space temperature from a single-gang box or a bare wall opening, this room sensor uses a 10,000 ohm Type II thermistor behind a four-way air flow enclosure that keeps the sensing element clear of self-heating. Screw terminal blocks take every connection to the building network, and a hex-secured cover resists casual removal.

The ACI Thermistor Room Series combines option flexibility with attractive styling in our "-R2" or "-R" style enclosures which include four-way air flow design to minimize self-heating to the sensor. These enclosures are offered in a White "-R2" or Beige "-R" color depending on the enclosure style. These units are designed to be mounted over a single gang junction box or hole in the wall using drywall anchors. Screw terminal blocks are available for making all connections to your building management system (network).
