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.

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.
5. Pull the wire through the wall and out 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” 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.
10. 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.
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.

Termination
Table 1: TerminationTable
* [CH3] and [CH4] are referenced to [GND] if (CG) is selected at time of order. [CH3] and [CH4] are referenced to each other if (DF) is selected at time of order.
** S1-4, Position (CG) connects [Temp-] terminal to the [GND] terminal internally. The (DF) position makes the [TEMP -] terminal oating. (See Fig.10)
*** This is the current output of the solid state sensor and must be congured as S1-4 set to (DF) to allow the 592 or 334 sensor to operate.
^ The reed contact to override [CH4] can be set up for (CG) which shorts the [CH4] output to [GND] or (DF) shorting the output terminals [CH3/CH4].
^^ The E-POT controls the output resistance setpoint and during override, the E-POT controls the resistance to <100 ohms for 3-5 seconds.
^^^ A reed dry contact across the sensor [TEMP+/-] is congured at time of order as a (-61) option.
~ The [TEMP] terminals are used for an external 10K-2 thermistor connection if the [EXT option] is selected. (wire=25’ max)

BAPI recommends using twisted pair of at least 22 AWG. 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 uctuating and inaccurate signal levels are possible when AC
power wiring is present in the same conduit as the signal lines.
Fig. 4: BAPI-Stat Circuit Board
Terminal Notes: (Related to table 1), [ ] = Terminal designation
1. Only one variable and output type per channel. [CH3] and [CH4] can be
overridden.
2. The [GND] terminal is always the reference for [V+], [CH1] and [CH2]
terminals.
3. The temperature output range is limited to between 32º to 158ºF
(0º to 70ºC).
4. Humidity setpoint range is limited between 0 to 100% RH.
5. The override is available on [CH3], [CH4] and [TEMP+/TEMP-] only.
6. Voltage outputs are limited to between 0 to 10 VDC and are only
referenced to [GND].
7. Current outputs are limited to between 0 to 20 mA and are only refer-
enced to [GND].
8. Resistive E-POT outputs are limited to a 1K, 10K, 50K or 100KW linier
POT, ±30%.
9. Resistive sensor [TEMP+/TEMP-] outputs may be any BAPI passive or
solid state sensor.
10. When using a 592/334 sensor, [TEMP+] is the supply (5 to 30 VDC)
[TEMP-] is the current output to the analog input @ 1µA/ºC and requires
S1-4 to be set for (DF). Reversal of the power will damage the sensor.
11. The Test and Balance option (-TB) cannot be used with the 592/334 sen-
sor.
12. If the BAPI-Stat has the external sensor option (-EXT), then it must be a
10K-2 thermistor purchased separately. The external sensor is wired to
the temp + and temp - terminals. A humidity signal or passive sensor are
not allowed in this conguration.

When the override button is pushed, the override output is active for
3 to 5 seconds. Simultaneously, the outline and center of the HUMAN
ICON on the display will be lled in for 3 to 5 seconds and then go
blank.
If you need visual indication of the override on the LCD display, the
controller must have a digital output connected to the sensor’s three-
pin EXT OVR terminal block, J6.
When appropriate power is connected between the EXT OVR common
and either 5 VDC or 24 VDC/VAC, both
the outline and center of the HUMAN
ICON will be lled in. When the external override is canceled, the HUMAN ICON’S outline will
remain lled in to show that the external override was used.
If power to the sensor is removed, the outline will be blank until the next time the external
override is used. This input is optically isolated from the rest of the device’s circuitry.

ADJUSTMENT PROCEDURE FOR EACH DIP SWITCH IN S1:
°F OR °C DISPLAY SELECTION [F/C Switch]
The “F/C” Switch allows for either °F or °C operation. Remove the cover from the
backplate and set the switch to the desired position.
DISPLAY READING OFFSET [MODE Switch] (3 to 5 button sensor required)
The Display Reading Offset “Mode” Switch lets you adjust the reading of the BAPI-
Stat display. For example if the display reads 70° but you wish it to display and
send a signal to your controller of 70.5°, you will enter an adjustment of 0.5. If the
display reads 40 %RH and you wish it to display and send a signal to your controller of 38% RH, you will enter -2.0.
1) Remove cover from backplate & slide the “MODE” switch on S1 to the “OFFSET” position.
The screen in gure 11 will appear on the display. If you previously entered an offset, the offset
you entered will show on the display. Either the F or C annunciator will be lit depending on the
position of “F/C” Switch
2) Press the Override button on the front of the sensor to advance to the screen for the parameter
you wish to change.
a. TEMPERATURE OFFSET - Screen P26 (gure 11)
b. HUMIDITY OFFSET - Screen P27 (gure 12)
c. DISPLAY MODE - Screen P28 (gure 13)
d. ACTIVE TEST & BALANCE MODE - Screen P29 (gures 14 & 15)
3) Use the Temperature Setpoint up and down arrows on the front of the sensor to select the
calibration needed.
a. TEMPERATURE OFFSET - Adjust the temperature ± 5°in 0.1° increments
b. HUMIDITY OFFSET - Adjust the humidity ± 5% in 0.1% increments
c. DISPLAY MODE - Adjust to 0 through 7 depending on the display mode you desire.
0 - Temperature in the main portion and %RH in the upper section
1 - %RH in the main portion and Temperature in the upper section
2 - The LCD toggles the locations at a ~5 second rate
3 - Temperature Only.
4 - Setpoint Display Only (SDO), Temp Setpoint in the main portion and %RH Setpoint in
the upper section
5 - Setpoint Display Only (SDO), %RH Setpoint in the main portion and Temp Setpoint in
the upper section
6 - Setpoint Display Only (SDO), The LCD toggles the setpoints between the locations at a
~5 second rate
7 - Setpoint Display Only (SDO), Temperature Setpoint only.
(Note: Selecting options 1, 2, 5 or 6 with units without %RH will default to mode 0)
d. ACTIVE TEST & BALANCE MODE - Setpoint buttons up or down toggles between ‘LO’
and ‘HI’ on the LCD. This mode is active only for models which use Channel 1 as a
temperature output. ‘LO’ will drive Channel 1 to it’s lowest voltage or current output. ‘HI’
will drive Channel 1 to it’s highest voltage or current output. (gures 14 & 15)
4) Press the Override button on the front of the sensor to ‘enter’ and store the change. Set the
“MODE” switch on S1 back to “RUN” and put the cover on the backplate.
SETPOINT LOCK OUT [SPLO Switch]
The “SPLO” Switch allows the setpoint buttons to be disabled. A switch setting of “ON” disables the
buttons.
PASSIVE TEMPERATURE SENSOR GROUNDING [TEMP switch]
Adjust DIP switch to “CG” for [TEMP –] connected to common ground [GND]
Adjust DIP switch to “DF” for [TEMP –] differential oating without connection to any ground.
The four DIP switches on the bottom of the board called S1 congure four different parameters (see Fig: 10).
1) Fahrenheit or Celsius temperature display “F/C” Switch.
2) Display Reading Offset “Mode” Switch for temperature and humidity appearance and output offset.
3) User Setpoint Lockout Enable “SPLO” Switch.
4) Passive temperature sensor differential ground or common ground conguration “TEMP” Switch.

POSSIBLE SOLUTIONS:
- Determine that the input is set up correctly in the controller’s and building automation
software.
- Check wiring for proper termination
- 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 that the interconnecting wires are connected to at the sensor end
and the controller end. Disconnect the interconnecting wires from the controller and the
sensor. With the interconnecting 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.
- Check power for proper polarity.
- Disconnect the power wires at the controller. Measure controller output for proper
power (see specications), if the voltage is outside the limits trouble shoot controller.
Reconnect power wires to controller when nished. If the measured voltage is above
the specication limit, you may have damaged the BAPI-Stat, contact your BAPI
representative.
- Disconnect the power wires at the sensor. Measure the wires for the same voltage as
at controller. If the voltage is different from that measured at the controller troubleshoot
wire. Reconnect power wires to sensor when nished.
- Measure the power at the sensor with the power connected for proper power
(see specications), if the voltage is outside the specication limits call your BAPI
representative.
