Terminations 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 fluctuating and inaccurate signal levels are possible when AC power wiring is present in the same conduit as the signal lines. Fig 5: Circuit Board Notes: On Common Ground (default) Models: Resistive Setpoint: Terminals “OVR2”, “SEN2”, and “SET2” are connected together internally but they are not connected to Ground “COM”. If you intend to use “COM” as common, then a jumper must be added from terminal “COM” to “SEN2”. This is only allowed on HumidityVoltage Output Models. Do not install this jumper on Humidity 4 to 20 mA Output models. Voltage Setpoint: Terminals “OVR2”, “SEN2”, and “SET2” are connected to Ground “COM”. This is only allowed on Humidity Voltage Output models. Do not adjust DIP Switch S1 to Humidity 4 to 20mA Output as the output will be shared with OVR2, SEN2, and SET2. On Differential Ground Models: All terminals are independent unless unit is configured for Voltage Setpoint (in that case SET2 is connected to COM). 0 to 5 VDC and 0 to 10 VDC Output Unit Termination TerminalFunction V+ ......................Power, see specifications section for details.

A high accuracy humidity reference is recommended. Note: For units with display, the offset is set via the programming pages described in the Optional Technician Adjustments section on page 5. Humidity Offset Potentiometer (R12) for units without display User Operation The display indicates temperature in degrees Fahrenheit or Celsius, relative humidity in %RH, temperature setpoint in degrees Fahrenheit or Celsius. Temperatures and relative humidity can be displayed in a rotating manner, see the Optional Technician Adjustments section. The Human Icon icon indicates that the override button has been pushed. Temperature: Displayed in Fahrenheit or Celsius. Can rotate between major and minor of display with relative humidity. Relative Humidity: Displayed in %RH. Can rotate between major and minor of display with temperature. Temperature Setpoint Slidepot: Moving the slidepot enough to change the setpoint will display the setpoint in the major of the display if equipped with display. The setpoint temperature display will flash the digits indicating that setpoint is being changed. Override Button: When the override button is pressed on display units, the Human Icon Icon will display. A dry resistance of less than 15 ohms appears across the override output. Latching the Icon to show that the system is in override requires that a dry contact on your controller be used to connect terminal XIN to ground. Note: The unit must receive a confirmation (ground) signal on the “XIN” terminal for the Human Icon to remain visible on the screen. Pressing the Override button will light the Human Icon icon; however, if no confirmation signal is received, then the Human Icon will go blank (disappear) after 5 seconds. Upon receiving a first confirmation (ground) signal on the “XIN” terminal, the Human Icon will show occupied (Solid). The Human Icon will then show unoccupied (Hollow) whenever the confirmation signal is removed and occupied when the signal is returned. The only way to blank the Human Icon from the display at this point is to cycle power Override Button Temp Setpoint Slider Minor Display Major Display Human Icon Fig 11: BAPI-Stat “Quantum” Humidity or Temp/Humidity Unit Indicators (Shown with all optional indicators) Hollow equals “Unoccupied” Fig. 12: Human Icon Solid equals “Occupied”Installation & Operating Instructions BAPI-Stat “Quantum” Room Humidity or Temperature and Humidity Sensor Building Automation Products, Inc., 750 North Royal Avenue, Gays Mills, WI 54631 USA Tel:+1-608-735-4800 • Fax+1-608-735-4804 • E-mail:sales@bapihvac.com • Web:www.bapihvac.com rev. 07/22/2041147_ins_quantum_hum Specifications subject to change without notice. 5 of 6 Adjustments for Units with a Display The optional technician adjustments allows a technician to set temperature and humidity offsets, display settings and output parameters.

Diagnostics 6 of 6 Possible Problems:Possible Solutions: General troubleshooting• Determine that the input is set up correctly in the controller and BAS. • Check wiring at the sensor and controller for proper connections. • Label the wire terminals 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. • Determine if the sensor is exposed to an external source different from the room environment (conduit draft). Plug the conduit or fill the handy box as necessary. DO NOT use silicon caulk. Incorrect Humidity• Check power supply/controller voltage supply • Disconnect sensor and check power wires for proper voltage (see specifications page) • Check all software parameters • Check the sensor humidity output against a reference. Measure the humidity at the sensor’s location using an accurate standard. Disconnect the humidity channel wires and measure the humidity signal with a multi-meter and compare to the reference, using the equations at right for the reference. If the output and reference differ by more than 5%, call BAPI technical support. Incorrect Temperature • Determine that the temperature sensor's wires are connected to the correct controller input terminals, and check the wires at the sensor and controller for proper connections. • Measure the physical temperature at the sensor's location using an accurate temperature standard. Disconnect the temperature sensor's wires (Terminals SEN1 & SEN2) and measure the temperature sensor's resistance across the output pins. Put the ohmmeter black lead on SEN2 and the red lead on SEN1. Compare the temperature sensor's resistance to the appropriate Sensor Resistance Table on the BAPI website (See below). If the measured resistance varies from the table by more than 5%, call BAPI technical support. How to Find The Temperature Sensor Resistance Table Find BAPI's web site at www.bapihvac.com; click on “Resource Library” and “Sensor Specs” and then click on the sensor type you have.
