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 that uctuating 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 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 will void the warranty.

Display and Front Panel Button Operation
The “X-Combo” is available with optional LCD, override and
setpoint buttons. See Fig. 10 for a fully featured sensor.
NUMERICAL DISPLAY:
The default numerical display shows current temperature, and
toggles to humidity display at an adjustable rate of 1 to 20
seconds. When the up/down buttons are pushed, the display
will show and adjust the current setpoint and hold that display
for 3 seconds. The unit can also be programmed to “setpoint
only” display or setpoint lockout. See pages 4-5.
BAPI-MAN INDICATOR (FIG. 11):
The BAPI-Man on the display indicates whether the room is in
the “Occupied” (solid) or “Un-occupied” (hollow) status.
Note: The unit must receive a conrmation (ground) signal on
the “OVR” terminal for the BAPI-Man to remain visible on the
screen. Pressing the Override button will light the BAPI-Man
indicator; however, if no conrmation signal is received, then
the BAPI-Man will go blank (disappear) after 5 seconds.

Display and Front Panel Button Operation continued...
Upon receiving a rst conrmation (ground) signal on the “OVR” terminal, the
BAPI-Man will show occupied (solid). The BAPI-Man will then show un-occupied
(hollow) whenever the conrmation signal is removed and occupied when the signal
is returned. The only way to blank the BAPI-Man from the display at this point is to
cycle power.
OVERRIDE BUTTON:
When the override button is pressed, the BAPI-Man will be displayed (solid) for 3-5

seconds and the override output will shunt or short for 5 seconds depending on the
override option selected. Momentary closure of the selected channel goes to its
minimum value for 5 seconds (Voltage goes to 0, 1, or 2 volts, current goes to 4mA, resistance goes to ~10Ω or the
channel 4 value goes to <1Ω on terminals “CH4 TEMP+” to “CH4 TEMP-”). If an override conrmation (ground) signal
is received on the “OVR” terminal, then the BAPI-Man will stay lled in, indicating an occupied status. If no conrmation
signal is received, then the BAPI-Man will revert to a hollow man display, indicating an un-occupied status. (See “BAPIMan Indicator” above for more information.)
TEMPERATURE SETPOINT:
Press the Setpoint Up/Down buttons once to enter the Setpoint Adjustment Mode. View the display to see whether
you are in Temperature or %RH Setpoint mode. If needed, press the Override Button once to toggle to Temperature
Setpoint mode. The current temperature setpoint will display for 5 seconds. When the Setpoint Up/Down buttons are
pressed in this mode, the temperature setpoint will change in one degree increments. It will only change within the
setpoint range that was ordered. After 5 seconds of no buttons being pushed, the sensor will go into the standard
display or toggle mode.
%RH SETPOINT:
Press the Setpoint Up/Down buttons once to enter the Setpoint Adjustment Mode. View the display to see whether you
are in Temperature or %RH Setpoint mode. If needed, press the Override Button once to toggle to the %RH Setpoint
Adjustment Mode. The current %RH Setpoint will display for 5 seconds. Pressing the UP/Down buttons will change the
selected setpoint by 1% increments. After 5 seconds of no buttons being pushed, the sensor will go into the standard
display or toggle mode.

Optional Technician Adjustments (The sensor set-up is factory set per your order. Set-up adjustments are not required)
The unit is shipped ready to install per the order and does not require any special setup or programming. The following
Set-up or Program Menu Changes are available if the installer decides to change the factory settings. Program Menu
changes require a display on the sensor. Non-display sensors must be factory congured.
Note: The Setpoint Up/Down Buttons and Override Button are used to make Menu changes. If the unit is ordered
without Setpoint Adjustment or Override, then buttons will be located on the back of the PCB inside the sensor. See
Figure 6 on page 2. These buttons will not be present on the PCB if the unit has been ordered with Setpoint and
Override.

Diagnostics - Temperature Output
Problems:
Temperature
Reading is
Incorrect
Possible Solutions
- Check for proper wire terminations and determine that the temperature input is set up correctly in the
controller and in the building automation software.
- Check the wiring between the sensor and controller. Label the terminals at the sensor end and the
controller end. Disconnect the interconnecting wires from the controller and the sensor. With the
wires disconnected, 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. 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 the sensor temperature output against a reference. Measure the temperature at the sensor’s
location using an accurate temperature standard. Disconnect the temperature channel wires and
measure the temperature signal with a multi-meter and compare to the reference temperature. For
resistive output units, use the “Sensor Specs” tables in the “Resource Library” section of the BAPI
website (www.bapihvac.com) for the reference. For voltage or current output units, use the equations
below for the reference. If the output and reference differ by more than 5%, call BAPI technical support.
- Make sure that the Test and Balance switch is in the correct position.
- Make sure that the temperature sensor element leads are not touching one another.
- Determine if the sensor is exposed to an external source different from the room environment (conduit
draft). Plug the conduit or ll the handy box as necessary. DO NOT use silicon caulk.
