PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
• THE OPTIONAL ACI/LCD MUST BE POWERED
WITH EITHER A 24 VAC 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
•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.
MOUNTING (Continued)
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 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 thermistors are 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.
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.
Wiring Instructions for optional ACI/LCD
The optional 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 2 to 4 conductor shield cable for the Temperature sensor, Set Point and
Override Outputs to the controller. ACI recommends18 to
22 AWG twisted pair wires or shielded cable for all sensor
installations.

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.

WIRING INSTRUCTIONS (Continued)
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.
TEMPERATURE DISPLAY ADJUSTMENTS
The Temperature Display may be adjusted by adjusting the ZERO or OFFSET Potentiometer (P2) as shown on
the above diagram. Adjust (P2) until the LCD Display reading matches your controller if 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.

PROBLEM
Sensor reading is incorrect
Sensor reads infinity/very high resistance
Sensor reads low resistance
Erratic readings
Display not working
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 theTemperatureVs 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
•Check the Power Connections
