Product Identication and Overview
Fig. 1: BAPI-Stat
“Quantum” with slider
setpoint adjustment,
override button and
provided screw pack.
The BAPI-Stat “Quantum” style room temperature sensor features a
large format LCD and slider setpoint adjustment. Additional options
include button override and communication jack.
The setpoint is available as a resistance or voltage output. The
override is a momentary closure signal that can be congured in
parallel with the sensor or setpoint, or as a separate momentary
output.
Mounting
JUNCTION BOX
1. Pull the wire through the wall and out of the junction box, leaving about 6
inches free.
2. Pull the wire through the hole in the base plate.
3. Secure the base to the box using the #6-32 x 1/2 inch mounting screw
provided.
4. Terminate the unit according to the guidelines in the Termination section.
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 ush 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 the 1/2” hole, leaving about 6” 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 the Termination section.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place. Secure the cover
by backing out the lock-down screws using a 1/16” Allen wrench until they are ush with the bottom of the cover.
NOTE: In a wall-mount application, the mixing of room air and air from within the wall cavity can lead to erroneous
readings, condensation, and premature failure of the sensor. To prevent this condition, plug the conduit hole with
insulation in the junction box.

Termination
BAPI recommends using twisted pair of at least 22AWG and sealant lled 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. BAPI’s tests show uctuating and inaccurate
signals are possible when AC power wiring is in the same conduit as the signal lines. If you are experiencing any of these
difculties, please contact your BAPI representative.

terminals SET1 & SET2 (-P). *If the unit is a
common ground conguration, see “Grounding
Note” below.
EXT-TEMP & EXT-GND .. Remote sensor terminals. No polarity. *If the
unit is a common ground conguration, see
“Grounding Note” below. To use these terminals,
a 10K-2 thermistor sensor must be ordered
separately and the temperature value from this
sensor will be displayed on the LCD but will not
be sent to the controller. Max wire distance for the
external sensor is 25 feet.
*Grounding Note:
Common Ground or Differential Ground congurations are selected per order (Common Ground is default). The
Differential Ground conguration indicates that SEN2, SET2, OVR2 and EXT-GND must all be wired separately (No
internal common connection). The Common Ground conguration indicates that SEN2, SET2, OVR2 and EXT-GND are
connected to GND internally (All internally common).

BAPI-Stat Quantum sensor comes with a display, slider setpoint adjustment and optional override.
Temperature:
Displayed in Fahrenheit or Celsius in the major display. (Field adjustable via the “F/C” switch on DIP Switch SW5.)
Temperature Setpoint Slider:
Moving the slidepot enough to change the setpoint will display the setpoint in the major of the display. The setpoint
temperature display will ash the digits indicating that setpoint is being changed.
Override Button:
When the override button is pressed on display units, the BAPI-Man Icon will display (Fig
8). A dry resistance of less than 15 ohms appears across the override output.
Note: The unit must receive a conrmation (ground) signal on the “OCCUPY” terminal for
the BAPI-Man to remain visible on the screen. Pressing the Override button will light the
BAPI-Man icon; however, if no conrmation signal is received, then the BAPI-Man will go
blank (disappear) after 5 seconds.
Upon receiving a rst conrmation (ground) signal on the “OCCUPY” terminal, the
BAPI-Man will show occupied (Solid). The BAPI-Man will then show unoccupied (Hollow)
whenever the conrmation signal is removed and occupied when the signal is returned.
The only way to blank the BAPI-Man from the display after it has received a rst
conrmation signal is to cycle power.

General Diagnostics
POSSIBLE PROBLEM: POSSIBLE SOLUTIONS:
Temperature reading is incorrect - Verify that the input is set up correctly in the controller’s and building automation
software.
- Check wiring for proper termination and check for opens or shorts.
- Check for corrosion at either the controller or the sensor. Clean off the corrosion,
re-strip the interconnecting wire and reapply the connection. In extreme cases,
replace the controller, interconnecting wire and/or sensor.
- Label the terminals at the sensor end and the controller end. Disconnect the
interconnecting wires from the controller and the sensor. With the wires separated
at both ends, measure the resistance from wire-to-wire with a multimeter. The
meter should read greater than 10 Meg-ohms, open or OL depending on the meter
you have. Short the interconnecting wires together at one end. Go to the other
end and measure the resistance from wire-to-wire with a multimeter. The meter
should read less than 10 ohms (22 gauge or larger, 250 feet or less). If either test
fails, replace the wire.
- Measure the physical temperature at the temperature sensor’s location using an
accurate temperature standard. Disconnect the temperature sensor wires and
measure the temperature sensor’s resistance across the sensor output pins with
an ohmmeter. Compare the temperature sensor’s resistance to the appropriate
temperature sensor table on the BAPI website. If the measured resistance
is different from the temperature table by more than 5% call BAPI technical
support. Find BAPI’s website at www.bapihvac.com; click on “Resource Library”
and “Sensor Specs” then click on the type of sensor you have. Don’t forget to
reconnect the wires.
- If the unit has a Test and Balance switch, make sure it is in the correct position.
Setpoint reading is incorrect - Make sure that the setpoint output is correct. Remove the setpoint output wire and
check the output for the correct resistance or voltage output. See the product label
for your specic range.
Override is not working correctly - Verify that the resistance across the override output is less than 15 ohms when the
override is pushed.
