## Room Series | Thermistor 

## **Wall Mount Enclosures, Thermistor** 

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 selfheating 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). An optional 3.175 mm (1/8 in) Black foam pad with pressure sensitive adhesive is available to insulate the sensor from thermal drafts within the wall or wall surface. A 1/16 in Hex driver is needed to secure the cover from being easily removed. The “LCD” option uses two temperature sensors to monitor the ambient air temperature in the space and is factory calibrated at a single point. 

## **Applications** 

Space Temperature Sensing, Decorative Wall Sensor Applications, Office Buildings, Schools, Colleges, Commercial Buildings, OEM Opportunities 

## **Warranty** 

The ACI Thermistor Room is covered by ACI’s Five (5) Year Limited Warranty. The warranty can be found in the front of ACI’s Sensors & Transmitters catalog, as well as on ACI’s website, workaci.com.
