Giving occupants a bounded say in their own space, this room temperature sensor pairs a 10,000 ohm Type II thermistor with a 0-100K adjustment and an override button wired back to the building management system. An LCD shows the space temperature alongside the dial. Four-way air flow through the enclosure keeps self-heating away from the sensing element.

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).
