Overview
The Vivarium BA/H(H200, H300)-SPV is a flush wipedown/washdown humidity transmitter with 2% or 3%
accuracies and an optional temperature sensor or transmitter and an optional water resistant pushbutton as well.
The temperature sensor can be either a Thermistor or RTD. The RH transmitter can be ordered with a combination
4 to 20mA/0 to 5VDC output or ordered with a 0 to 10V or 2 to 10V output. The unit is powered with 10 to 35VDC.
The voltage output units can also be powered with AC
volts (see spec). The optional temperature transmitters
come in 4 to 20mA, 0 to 5V or 0 to 10V output.

Mounting
Mounting hardware is provided for both junction box and drywall installation.
Junction Box
1. Pull the wire through the wall and out of the junction box, leaving about six
inches free.
2. Terminate the unit according to the guidelines in the Termination section.
3. Secure the plate to the box using the #6-32x1/2 inch mounting screw provided
or with security screws which are sold separately.
Drywall Mounting
1. Place the plate against the wall where you want to mount the sensor and
mark the two mounting holes.
2. Drill two 3/16” holes in the center of each marked mounting hole. Insert a
drywall anchor into each hole.
3. Cut hole between the mounting holes that clears the apparatus mounted on
the plate. Pull the sensor barrel through the wall hole, leaving about six inches
free.
4. Terminate the unit according to the guidelines in the Termination section.
5. Secure the plate to the drywall anchors using the #6x1” mounting screws
provided.

Junction Box
Filter Cover
Please install protective cover over stainless steel filter before any wash down procedures begin. This will insure the correct long life operation of the sensor. Failing to cover the sensor during wash down voids the warranty and could severely
shorten the life of the sensor.

Termination - Units with Humidity Transmitter and Optional Thermistor or RTD Temperature Sensor
BAPI recommends using twisted pair of at least 22AWG and sealant filled 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 with inductive loads such as motors, contactors
and relays. BAPI’s tests show that fluctuating and inaccurate signal levels are possible when AC power wiring is present
in the same conduit as the signal lines.

Sensor Termination and Troubleshooting
10577_ins_hum_therm_spv
rev. 07/20/12
Diagnostics - Humidity
Possible Problems:
Unit will not operate
Possible Solutions:
- Check for proper supply power. (See pgs 2-4 for wiring diagram and power specs)
Humidity output is at its maximum - Make sure the humidity sensor is installed properly and is not shorted.
value: 5V, 10V or 20mA
- Make sure the blue or blue/black wires to the humidity sensing element in the probe
are not shorted. Shorted wires will cause the humidity output to go to its maximum
value.
Humidity output is at its minimum
value: 0V, 2V or 4mA
- Make sure the humidity sensor is installed properly.
- Make sure the blue or blue/black wires to the humidity sensing element in the probe
are not broken or disconnected. Disconnected or open wires will cause the humidity
output to go to its minimum value.
Humidity reading in controller’s
software appears to be off by
more than the specified accuracy
- Check all software parameters
Output
4 to 20mA
0 to 5VDC
0 to 10VDC
2 to 10VDC
Humidity Formula
%RH =(mA-4)/0.16
%RH = V/0.05
%RH = V/0.1
%RH = (V-2)/0.08
- Determine if the sensor is exposed to an external air source different from the
measured environment, such as air infiltration through the wiring conduit.
- Check the humidity transmitter output against a calibrated reference such as a 2%
accurate hygrometer. Measure the humidity at the sensor’s location using the reference
meter, then calculate the humidity transmitter output using the humidity formula at left.
Compare the calculated output to the actual transmitter output (see wiring diagrams
on pgs 2-4 for the humidity transmitter output wire colors). If the calculated output is
different from the measured output, contact BAPI technical support.
Diagnostics - Thermistor or RTD Temperature Sensor
Possible Problems:
Controller reports Incorrect
temperature
Possible Solutions:
- Confirm the input is set up correctly in the controller’s software
- Check wiring for proper termination and verify that the sensor wires are not
physically shorted or open
- Measure the temperature at the sensor’s location using an accurate standard.
Disconnect the temperature sensor wires and measure the temperature sensor’s
resistance with an ohmmeter. Compare the sensor’s resistance to the appropriate
temperature sensor table on the BAPI website. If the measured resistance is
different from the temperature table by more than 5%, call BAPI technical support.
(BAPI’s web site is found at www.bapihvac.com; click on the button labeled Sensor
Specs on the left of the screen and then click on the type of sensor you have.)
Diagnostics - T100, T1K or T10K Temperature Transmitter
Possible Problems:
Unit will not operate
Possible Solutions:
- Check for proper supply power. (See pages 3-4 for wiring diagram and power specs)
Temperature sensor reading
is inaccurate at the controller
software
- Check all software parameters.
Voltage Temperature Equation
T = TLow + (V x TSpan)
VSpan
T
= Temperature at sensor
TLow = Low temperature of span
THigh = High temperature of span
TSpan = THigh - TLow
VLow = Low transmitter voltage
usually=(0 or 2v)
VHigh = High transmitter voltage
usually=(5 or 10v)
VSpan = VHigh - VLow
V
= Signal reading in volts
- Determine if the sensor is exposed to an external air source different from the
intended measured environment.
- Make sure the temperature sensing element wires are not open or shorted.
- Check the temperature transmitter output against a calibrated reference. Measure
the temperature at the sensor’s location, then calculate the transmitter output using
the Voltage Equation or 4 to 20mA Equation
4 to 20mA Temperature Equation
formulas. Compare the calculated output to the
T = TLow + (A -4) x (TSpan)
actual temperature transmitter output (see the
16
wiring diagrams on pgs 3-4 for the temperature
T
= Temperature at sensor
transmitter output wire colors). If the calculated
TLow = Low temperature of span
output is different from the measured output,
THigh = High temperature of span
TSpan = THigh - TLow
