Product Identication and Overview
Designed for use in applications with Fan Coils, Heat Pumps, Unit Ventilators
and other Terminal Units, the RuPM provides local indication of Temperature
and Setpoint with Setpoint Adjust, Override and Fan Speed and Mode Control.
The unit is available with an optional 3.5mm (1/8”) or RJ11 Communication
Jack and a Test and Balance Switch. The Setpoint is displayed for a short time
after an adjustment. The Setpoint can be programmed to display as an offset
(i.e. -2, -1, 0, 1, 2) or as a value within a specied temperature range (i.e. 65 to
80 °F). The Override is a momentary signal that can be congured in parallel
with the Sensor or Setpoint (Specied at time of order). Fan Speed or Mode
are provided as a single analog output (resistive) and include appropriate LED
indicators on the face of the unit.

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 the junction box, leaving about 6” 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” 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. Use a pencil to mark 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. Pull the wire
through the wall and out the 1/2” hole, leaving about 6 inches free.

5. Pull the wire through the hole in the base plate.
6. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
7. Terminate the unit according to the guidelines in the Termination Section.
8. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
9. 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.
NOTE: In a 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 premature failure of the sensor. To prevent these conditions, seal the conduit leading to the junction box and
use BAPI’s adhesive backed, foam insulating pad centered over the hole (order part number BA/FOAMBACK).

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 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.
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.

Sensor Display Offset
The sensor display offset is enabled by holding down the setpoint UP and DOWN buttons simultaneously for 3 seconds.
The display will then show the last offset value. Adjust the offset up or down ±3º in 0.5º steps using the setpoint UP or
DOWN buttons. The offset affects both the display and the temperature sensor output. After 10 seconds without any
button depression, the display will return to normal and the new offset is retained.
Fan Speed Keypad Function
°C/°F Toggles LCD between °C/°F temperature & setpoint display.
TEMP Raises or lowers the desired setpoint temperature. Setpoint temperature
will be displayed on the LCD as the keys are used. LCD will revert to
normal temperature display after a few seconds of no key presses.
FAN Adjusts the fan speed mode as indicated by the red LEDs in the fan
speed display area.
OVERRIDE Sets the appropriate output [Sensor or Setpoint] to it’s lowest resistance
value. Output maintains as long as the key is pressed plus 2 seconds
once released.
Fan & Mode Keypad Function
MODE Sets unit mode (Heat, Off, Cool) as indicated by the red LEDs in the
Mode area.
TEMP Raises or lowers the desired setpoint temperature. Setpoint
SETPOINT temperature will be displayed on the LCD as the keys are pressed.
LCD will revert to normal temperature display after a few seconds of
no key presses.
FAN Adjusts the fan operation as indicated by the red LEDs in the fan
display area.

resistance value. Output maintains as long as the key is pressed plus
a few seconds once released (Only 5-button units)

Diagnostics
POSSIBLE PROBLEMS:
Temperature reading is
incorrect
POSSIBLE SOLUTIONS:
- 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. Disconnect the temperature sensor wire (Terminal 1) and measure
the temperature sensor’s resistance across the output pins with an ohmmeter (Make sure
the RuPM is powered for this measurement). If the measured resistance is different from
the sensor’s temp/resistance table 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.
rev. 06/24/15
Setpoint reading is
incorrect
Override is not working
correctly
Fan speed is incorrect
- Make sure that the setpoint output wiring is correct. Remove the setpoint output wire
(Terminal 3) and check the output for the correct resistance or voltage output. (Make sure
the RuPM is powered for this measurement.) See the product label for your specic range.
Don’t forget to reconnect the wire.
- Check that the resistance across the override output is less than 5 ohms when the
OVERRIDE button is pushed (Make sure the RuPM is powered for this measurement.)
Disconnect the temperature sensor wire (Terminal 1) for override in parallel with sensor
OR disconnect the setpoint output wire (Terminal 3) for override in parallel with setpoint.
- Check the wires at the sensor and controller for proper connections.
- Make sure that the FAN SPEED output is correct (Make sure the RuPM is powered for
this measurement). Remove the fan output wire (Terminal 4) and check the output for the
correct resistance output. Push the FAN SPEED button and check the resistances when
each LED is lit. See the “Fan Speed and Mode Control Output Resistances” above for
your specic output resistances. Don’t forget to reconnect the wire.
