MOUNTING INSTRUCTIONS
Take care when mounting. Check local code for
mounting height requirements. Typical mounting
heights are 48-60" (1.2-1.5 m) o the ground and at
least 1.5' (0.5 m) from the adjacent wall. The sensor
should be mounted in an area where air circulation is
well mixed and not blocked by obstructions.
Separate the cover from the base. Attach the base
directly to the wall or to a standard 2" x 4" junction
box using the (2) #6-32 x 1" screws provided.
*Reference FIGURE 2 (next page)
For optimal temperature measurement, follow
these tips:
• Do not install on external walls.
• Avoid air registers, di users, vents, and windows.
• Avoid con ned areas such as shelves, closed
cabinets, closets, and behind curtains.
• Eliminate and seal all wall and conduit penetrations.
Air migration from wall cavities may alter
temperature readings.
• A thermally-insulated backing should be used when
tting to solid walls (concrete, steel, etc.). ACI part:
A/ROOM-FOAM-PAD
• Do not install near heat sources, eg: lamps,
radiators, direct sunlight, copiers, chimney
walls, walls concealing hot-water pipes.
Refer to the Wiring Instructions (p. 2-3) to make
necessary connections. Tighten the cover down,
using the (2) 1/16" Allen screws located in the

- Page 2 FIGURE 2: MOUNTING WIRING INSTRUCTIONS ACI recommends 16 to 26 AWG twisted pair wires or OPTIONAL INSULATING GASKET shielded cable for all sensors. Signal wiring must be run separate from low and high voltage wires (24/120/230 VAC). All ACI thermistors are both non-polarity and non-position sensitive.
- Page 3 C-BUS DEVICES prevent any chance of shorting. ISOLATED Note: ACI’s stats are not two-way communicating. Communication jacks allow the user to query and modify operating parameters of the local room terminal unit from the portable operator’s terminal (laptop). This feature allows a technician to commission or service the controller via the sensor.
- Page 4 Accuracy @ 0-70 °C (32 - 158 °F): WARRANTY The ACI Room Series temperature sensors are covered by ACI’s Five (5) Year Limited Warranty, which is located in the front of ACI’S SENSORS & TRANSMITTERS CATALOG or can be found on ACI’s website: www.workaci.com.
