Description
The ACI Thermistor Room Series combines option flexibility with attractive styling in the R2 style enclosure which includes four-way air flow design to minimize self-heating to the sensor. 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).
Applications: Space Temperature Sensing, Decorative Wall Sensor Applications, Office Buildings, Schools, Colleges, Commercial Buildings, OEM Opportunities
