PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
• THE ACI/LCD MUST BE POWERED WITH
EITHER A 24 VAC OR 9-35 VDC POWER
SOURCE.
GENERAL INFORMATION
The S/10K-S series temperature sensors are a system
specic, plug n’play type sensor that can be ordered
with a 10K Thermistor, Setpoint, “After Hours”
Override (Bypass), and (2) 6 Pin RJ11 Phone Jacks.
The sensor must be connected to the BAS (Building
Automation System) using a 6 Conductor cable
with (2) 6 Pin RJ11 Male phone connectors.
MOUNTING INSTRUCTIONS
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.
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.
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.
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
A 6 Conductor Cable with (2) Male RJ11
connectors must be plugged into the 6 Pin
Female RJ11 Phone Jack located on the back
of the enclosure. No other connections must
be made for the sensor to work with the
Building Automation System. ACI
recommends the use of a 6 Conductor (3 Pair)
24 AWG, NEC Class 2 Cable with a maximum
length of 100 Feet be used for all sensor
installations.
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.
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
TheTemperature 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.

PRODUCT SPECIFICATIONS
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
•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
•Check the Power Connections
