“BAPI-Stat 3” JCI Room Sensor

Overview and Identication

The BAPI-Stat 3 is a multiple output transmitter for temperature and
humidity with setpoint capability for both and occupied/unoccupied
override switching. The large easy-to-read display is ideal for cross
room viewing and membrane pushbuttons are designed for easy
operation and cleaning.

A fully featured unit can have 4 active channel outputs, override and
a passive sensor output. All ranges are factory set, however each
temperature and humidity sensor channel has a local offset adjust for
ne tuning. The display can be locally customized to the customer’s
preference.

without humidity setpoint will only have

three buttons.)

Mounting

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 backplate to the box using the #6-32 x 1/2 inch
mounting screws 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 screw using a 1/16”
allen wrench until it is 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.

Mounting hardware is

provided for both junction

box and drywall installation

(Junction box installation

5. Pull the wire through the wall and out the 1/2” hole, leaving about
six inches free. Pull the wire through the hole in the base plate.

6. Secure the base to the drywall anchors using the #6 x 1” mounting screws provided.

7. Terminate the unit according to the guidelines in the Termination section.

8. 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 screw using a 1/16” allen wrench until it is ush with the sides of the cover.

shown).

Note: In any 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 sensor failure. To prevent these conditions, BAPI recommends sealing the conduit leading to the junction
box with berglass insulation.

Front Panel Description

Humidity Setpoint: When the left set of s or t buttons are pressed, the relative humidity
setpoint will display. As the buttons are pressed again, the display will change in 1%
increments with each press. The setpoint will change only within the specied range ordered.

Temperature Setpoint: When the right set of s or t buttons are pressed, the temperature
setpoint will display. As the buttons are pressed again, the display will change in one degree
increments with each press. The setpoint will change only within the specied range ordered.

Pressing and holding any setpoint button will auto increment/decrement the setpoint value
The setpoint will change only within the specied range (as ordered).

Override: When the button is pressed, the Occupied/Unoccupied Icon will show
for a few seconds.

To retain the Occupied/Unoccupied Icon , you must energize J6*.

(*For more information on Occupied/Unoccupied Icon, see the “Termination” and the
“Display Occupancy Mode Termination” sections)
