PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
MOUNTING INSTRUCTIONS
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.
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.
*Reference FIGURE 2 (p. 2)
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
*Reference FIGURE 3 (next page)
•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) to make
necessary connections. After wiring, attach the cover
to the base by snapping the top of the cover on rst
and then the bottom. Tighten the cover down, using
the (2) 1/16” Allen screws located in the bottom of
the housing. A 1/16” Hex driver is needed to secure
the cover to the base.

WIRING INSTRUCTIONS
ACI recommends 16 to 26 AWG twisted pair
wires or 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. The number of wires
needed depends on the application. All
wiring must comply with all local and
National Electric Codes.
Note: When using a shielded cable, be sure
to connect only (1) end of the shield to
ground at the controller. Connecting both
ends of the shield to ground may cause a
ground loop. When removing the shield
from the sensor end, make sure to properly
trim the shield to prevent any chance of
shorting.

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.
W.E.E.E. DIRECTIVE
At the end of their useful life the packaging and product should be disposed of via a suitable recycling
centre. Do not dispose of with household waste. Do not burn.
TROUBLESHOOTING
PROBLEM
Sensor reading is incorrect
Sensor reads innity/very high resistance
Sensor reads low resistance
Erratic readings
SOLUTION(S)
•Verify sensor wiring to controller is not damaged and has continuity.
•Verify sensor or wires are not shorted together.
•Verify controller is setup for correct sensor curve.
•Disconnect wires from sensor terminal block, tighten terminal block
screws down, and take a resistance (ohm) reading with a multimeter.
•Compare the resistance reading to the Temperature Vs Resistance
Curves online: http://www.workaci.com/content/thermistor-curves-0
•Verify proper mounting location to conrm no external factors are
aecting reading.
•Sensor or wires are open.
•Sensor or wires are shorted together.
•Condensation on PCB board
•Bad wire connections.

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.
SETPOINT CONTROL
Adjust slider at bottom of housing for set point control. Slide to right to increase set point temperature. Slide to
left to decrease temperature control. Units can be setup from factory for Direct Acting (resistance increases
when adjusted to right), or Reverse Acting (resistance decreases when adjusted to right).
OVERRRIDE OPTIONS
Override will be set to Override Set Point.
