PRECAUTIONS
• DO NOT RUN THEWIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
• THE OPTIONAL ACI/LCD MUST BE POWERED
WITH EITHER A 24VAC OR 9-35 VDC POWER
SOURCE.
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 (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
*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.

MOUNTING (Continued)
Additional Mounting Instructions for
optional ACI/LCD
The ACI/LCD is shipped as a two-piece unit. The
LCD Module must be unplugged from the 10
pin connector before the base of the sensor
may be mounted to either the drywall or over a
standard 2” x 4” Junction Box using the
mounting hardware provided. The LCD Module
should then be gently inserted into the 10 pin
connector. The cover may now be placed onto
the unit and tightened down using the (2) Allen
screws at the bottom of the housing.
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 sensors are non-position sensitive.
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. The ACI/LCD must be powered with either a 24 VAC or 9-35 VDC power source. The
ACI/LCD uses a half-wave bridge rectier to convert the AC voltage to a useable DC voltage. Two separate
cables must be pulled for the ACI/LCD to work properly. One 2 conductor 18 to 22 AWG shielded cable for
the supply voltage and a second 18 to 22 AWG 3 to 8 conductor shield cable for the Temperature sensor,
Set Point and Override Outputs to the controller.

TROUBLESHOOTING
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 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.

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.
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.
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.
OFFSET CALIBRATION
The ACI/UVC is factory calibrated to within +/- 1 °F. For more
precise calibration adjust the Oset Potentiometer (P4) to a
single point thermometer after the sensor is installed. This
sensor will be aected by lead wire resistance, an oset
adjustment may be necessary.
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. TERMINAL BLOCKS
