PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
GENERAL INFORMATION
The ACI/Enhanced sensor is provided with the
setpoint, override, LED, and communication jack.
The ACI/10K-CP-ALC sensor can have the sensor,
setpoint, and override options.
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
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. All thermistor type
room units are supplied with a two-pole
terminal block. The number of wires needed
depends on the application. All wiring must
comply with all local and National Electric
Codes. After wiring, attach the cover to the
base by snapping the top of the cover on rst
and then the bottom.

WIRING INSTRUCTIONS (Continued)
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.

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.
PROBLEM
Sensor reading is incorrect
Sensor reads infinity/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 theTemperature 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
