Terminations
Note1: The termination screws should be turned fully Counter Clockwise (CCW) to open the jaws fully. Then insert the eld wire and turn
the screws Clock Wise (CW) to pinch the wire fully closed. If the jaws are left partially open, the inserted wire may be on bottom of, instead
of inside, the jaws causing a poor connection.
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 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 recommends against wiring the sensor with power applied as accidental arcing may damage the product and void the warranty.

Mounting
Mounting hardware is provided for both junction box and drywall installation (junction box installation shown).
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 plate 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 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 of 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 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.
10. 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.
Fig 2: Mounting to a Junction Box
NOTE: In any wall-mount application, the wall temperature and the temperature of the air within thewall cavity can cause erroneous readings. The
mixing of room air and air from within the wall cavity can lead to condensation, erroneous readings and premature failure of the sensor. To prevent these
conditions, seal the conduit leading to the junction box or ll the box with insulation.

The optional technician adjustment procedure allows temperature and humidity offsets, °F or °C
display units or display information to be changed at any time. When the unit is powered up,
pressing the tact switch at SW1 will enter the user calibration adjustment mode (See Figure 4).
When pressed, the LCD will show page zero, P0. The page numbers auto-scroll to P5 and then
the unit returns to the normal run mode. Pressing SW1 when any page number is displayed will
show the calibration value that is associated with that page. The variable will auto-scroll and will
show all the allowed values for the selected page. Pressing SW1 when the variable value you
need is shown will record that value and return to showing page numbers.
* When active means when moving the setpoint slider.
** Display toggles through selections.

The display indicates dry bulb temperature in degrees Fahrenheit or Celsius, dew point in degrees Fahrenheit or Celsius, relative hu-
midity in %RH, temperature setpoint in degrees Fahrenheit or Celsius. Temperatures and relative humidity can be displayed in a rotat-
ing manner, see the Optional Technicians Adjustments section. The BAPI Man icon indicates that the override button has been pushed.
Dry Bulb Temperature: When dry bulb temperature is displayed the INSIDE icon as well as the appropriate units icon are illuminated.
Dew Point Temperature: When dew point temperature is displayed the letters dP are displayed for 2 seconds just before the dew
point temperature is displayed. Then the dew point temperature is displayed with the appropriate units icon illuminated, the INSIDE
icon is off.
Relative Humidity: When relative humidity is displayed the INSIDE icon as well as %RH are illuminated.

Setpoint Slide-Pot: When the temperature setpoint is active (see technician adjustments), moving the slide pot enough to change the
setpoint by one degree will display the setpoint on display units.
Override Button: When pressed, the override icon will display on display units. A dry resistance of less than 15 ohms appears
across the override output (OVR1 to OVR2). Latching the Icon to show that the system is in override requires that a digital output on
your controller be used to connect terminal EXT-OVR to power supply ground.

Diagnostics
5 of 5
Possible Problems: Possible Solutions:
General troubleshooting • Determine that the input is set up correctly in the controller's and building automation
software.
• Check wiring at the sensor and controller for proper connections.
• 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.
Incorrect Humidity • Check power supply/controller voltage supply
• Disconnect sensor and check power wires for proper voltage (see specications below)
Check all software parameters
• If available, check the sensor against a calibrated instrument such as a hygrometer
• Determine if the sensor is exposed to an external environment different from the room
(conduit draft)
Incorrect Temperature • Determine that the temperature sensor's wires are connected to the correct controller
input terminals and are not loose.
• Check the wires at the sensor and controller for proper connections.
• Measure the physical temperature at the temperature sensor's location using an
accurate temperature standard.
Output to Controller
Disconnect the temperature sensor's wire (Terminals SEN1 & SEN2) and measure
the temperature sensor's resistance across the sensor output pins with an ohmmeter.
Put the ohmmeters black lead on Terminal SEN2 and the red lead on Terminal SEN1.
Compare the temperature sensor's resistance to the appropriate temperature sensor
table on the BAPI web site (See below). If the measured resistance is different from
the temperature table by more than 5% call BAPI technical support. Don't forget to
reconnect the wires.
How to Find Temperature Sensor Resistance
Find BAPI's web site at www.bapihvac.com; click on the button labeled SENSORS on
the left of the screen and then click on the sensor type you have.
• Make sure that the sensor leads are not touching one another.
• Determine if the sensor is exposed to an external environment different from the room
(conduit draft)
Humidity Output Selection
Figure 9: Output Jumpers
Moving the jumper on connector J4 will change the humidity output from 4 to 20mA,
0 to 5VDC or 0-10VDC. Figure 9 shows the jumper in the 4 to 20mA, position. The 0-10
VDC jumper is used for the 2-10 VDC signal if an H212 or H312 was ordered.
