Termination
BAPI recommends using twisted pair of at least 22AWG and sealant filled connectors for all wire connections. Larger
gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device’s wiring in the same conduit as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with
wiring used to supply highly inductive loads such as motors, contactors and relays. BAPI’s tests show that fluctuating and
inaccurate signal levels are possible when AC power wiring is present in the same conduit as the signal lines. If you are
experiencing any of these difficulties, please contact your BAPI representative
BAPI does not recommend wiring the sensor with power applied as accidental arcing may
damage the product and will void the warranty

1. For 592-10K units, sensor is measured at Sen +Gnd.
For 592 units, a 10K ohm 0.1% resistor must be
installed between the controller input and ground.
2. Override (O/R) and Setpoint (Set) are with reference
to Gnd.

V+ = +7 to 30 VDC input
Sen = Sensor out
O/R = Override
Set = Setpoint output, voltage(see

Thermistor Reading_______
The actual temperature reading
according to a thermometer that
is certified traceable to
recognized standards by the
National Institute of Standards and
Technology (NIST).
To correct the Sensor Reading, simply add the offset value to the sensor reading so that it equals the thermometer reading.
e.g. Therm Reading 74.6 Sensor Reading 73.0 Offset +1.6
Correction: Add (+1.6) °F to the sensor for an accurate reading: 73 + 1.6 = 74.6°F
e.g. Therm Reading 75.4 Sensor Reading 77.2 Offset -1.8
Correction: Add (-1.6) °F to the sensor for an accurate reading: 77.2 + (-1.8) = 75.4°F
Sensor Reading ______
The temperature reading according
to the AD592 sensor, using the
output in either uA or V and
converting the output to a
Fahrenheit temperature.
Troubleshooting
Offset_______
The difference between the
Thermometer Reading and the
Sensor Reading.

1. Set your meter to the V setting.
2. Measure the voltage between the “Sen” and
“GND.” See diagrams above in the Termination
section.
3. Compare the voltage reading to the voltage listed
in the output table.
4. If the sensor reads significantly lower or 0, then
your sensor may be shorted.
5. If the sensor reads significantly higher then the
sensor may be open.
6. If the sensor reads properly, verify that the
controller is operating correctly.

Mounting hardware is provided for both junction box and drywall installation (junction box installation shown).
Junction Box
1. Pull the wire through the wall and out of the junction box, leaving about six inches free.
2. Pull the wire through the hole in the base plate.
3. Secure the plate to the box using the #6-32 x 1/2 inch mounting screw provided.
4. Terminate the unit according to the guidelines in Termination on page 1.
5. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place.
6. Secure the cover by backing out the lock-down screws using a 1/16" allen wrench until they are flush with the bottom
of the cover.
Drywall Mounting
1. Place the base plate against the wall where you want to mount the sensor.
2. Using a pencil mark out the two mounting holes and the area where the wires will come through the wall.
3. Drill two 3/16" holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.
4. Drill one 1/2" hole in the middle of the marked wiring area.
5. Pull the wire through the wall and out of the 1/2" hole, leaving about six inches free.
6. Pull the wire through the hole in the base plate.
7. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
8. Terminate the unit according to the guidelines in Termination on page 1.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
10. Secure the cover by backing out the lock-down screws using a 1/16" allen wrench until they are flush with the bottom
of the cover.
NOTE
In a wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause erroneous
readings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous readings and
premature failure of the sensor.
T o prevent these conditions, seal the conduit leading to the junction box and use BAPI’ s adhesive backed, foam insulating
pad centered over the hole(order part number BA/FOAMBACK).
