BAPI BAPI-Stat 4 Sensor Catalog Page
BAPI-Stat 4 Sensor, w/Display, Button Setpoint, Fan or System Mode Control
Product Identication and Overview
The BAPI-Stat 4M room temperature sensor
features a large format LCD and pushbutton
setpoint adjustment. Additonal options include
pushbutton override, fan speed and mode
adjustments.
The setpoint is available as a resistance or
voltage output. The override is a momentary
closure signal that can be congured in parallel
with the sensor or setpoint, or as a separate
momentary or latching contact output. A 3.5mm
(1/8”), RJ11 or RJ22 communication jack can
also be mounted in the unit’s base to provide
direct access to the network.

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
difculties, please contact your BAPI representative.
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity and wiring
connections are important to a successful installation. Not observing these recommendations may damage the
product and void the warranty.

*Grounding Note:
Common Ground (-CG) or Differential Ground (-DF) congurations are selected per order. The Differential Ground
conguration (-DF) indicates that SEN2, SET2, OVR2 and RSEN2 must all be wired separately (No internal common
connection). The Common Ground conguration (-CG) indicates that SEN2, SET2, OVR2 and RSEN2 are connected to
GND internally (All internally common). This is true of all Common Ground units except when ordered with the Override as
a Latching Switch option (-L#). In this case, OVR2 is isolated and not internally connected to SEN2, SET2 and RSEN2.

........Override output (Dry contact) The contact can be
ordered as a momentary shunt across the sensor

as a separate latching contact (-L#). *If the unit

“Grounding Note” below.
... Remote sensor option (-ES). No polarity. *If the
unit is a common ground conguration (-CG),
see “Grounding Note” below. A 10K-2 thermistor
sensor must be ordered separately and the
temperature value is displayed on the LCD. Note:
If a temperature reading is needed at the controller,
then a second sensor must be ordered and wired
independently.

Optional Test and Balance Switch (S1)
On the Test and Balance Switch, the NORM position allows the real sensor to be monitored. The HIGH position forces the
output to a very hot reading and the LOW position forces a very cold reading (see Table below).
