These enclosures are offered in a White “-R2” or Beige “-R” color depending on the enclosure style. All units are designed to be mounted over a single gang junction box or hole uaa a7) in the wall with the use of drywall anchors. Screw terminal blocks are provided for making all connections to the temperature sensor, Set Point, “After Hours” Override, and Communication Jacks for easy access to your building management system. An optional 1/8” Black foam pad with pressure sensitive adhesive is available to insulate the sensor from thermal drafts within the wall or wall surface temperature. A 1/16” Hex driver should be used 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 **The ACI Nickel Room Series 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 web site,** workaci.com **.** ## PRODUCT SPECIFICATIONS **==> picture [457 x 359] intentionally omitted <==** **----- Start of picture text -----**
