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.
