JUNCTION BOX

1. Pull the wire through the wall and out of the junction box, leaving about sixinches 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 downand snapping it into place.

6. Secure the cover by backing out the lock-down screws using a 1/16 Allenwrench 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 thewires will come through the wall.

3. Drill two 3/16 holes in the center of each marked mounting hole. Insert adrywall 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.

NOTE: In a wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause erroneousreadings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous readings and prematurefailure of the sensor. To prevent these conditions, seal the conduit leading to the junction box and use BAPIs adhesive backed, foaminsulating pad centered over the hole (order part numberBA/FOAMBACK).

Designed for use in applications with Fan Coils, Heat Pumps, Unit Ventilators and other Terminal Units, the RuPM provides localindication of Temperature and Setpoint with Setpoint Adjust, Override and Fanspeed options. An optional 3.5mm (1/8) or RJ11 Com-munication Jack can be mounted in the base to provide direct access to the network. The Setpoint is displayed for a short time afteran 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 temperaturerange (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). Fanspeed is provided as a single analog output (resistive) and includes appropriate LED indicators on the face of theunit (Specied at time of order).

Termination

BAPI recommends using twisted pair of at least 22AWG and sealant lled connectors for all wire connections. Larger gauge wire maybe required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.

Do NOT run this devices wiring in the same conduit as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with wiring usedto supply highly inductive loads such as motors, contactors and relays. BAPIs tests show that uctuating and inaccurate signal levels

are possible when AC power wiring is present in the same conduit as the signal lines. If you are experiencing any of these difculties,please contact your BAPI representative.

Notes:*The Ground (Common or GND) terminal [2] is the common for the power, temperature

sensor, fan speed and setpoint.

**Power requirements are shown in the Specifcations Section.

The Override can be factory set to be in parallel with the temperature sensor Terminal [1]-[2] or setpoint Terminal [3]-[2]. Override conguration is NOT eld selectable.

Table: 4 Fig. 13 C11 Comm Jack

The sensor display offset is enabled by holding down the setpoint UP and setpoint DOWN buttons simultaneously for 3 seconds. Thedisplay will then show the last offset value. Then adjust the offset up or down 3 in 0.5 steps using the setpoint buttons UP or DOWN.The offset affects both the display and temperature sensor output. After 10 seconds without any button depression the display will go tonormal and the new offset is retained.

C/F Toggles LCD between temperature & setpoint display in C/F units.

TEMP Raises or lowers the desired set-point temperature. Set-point temperaturewill be displayed on the LCD as the keys are used. LCD will revert to normaltemperature display after a few seconds of no key presses.

FAN Adjusts the fan speed mode as indicated by the red LEDs in the fan speeddisplay area.

OVERRIDE Sets the appropriate output [Sensor or Setpoint] to its lowest resistance value.Outputs maintains as long as the key is pressed plus 2 seconds once released.

MODE Sets unit MODE (Heat, Off, Cool) as indicated by the red LEDs in the Mode area.

TEMPERATURE Raises or lowers the desired set-point temperature. Set-point temperature will beSETPOINT displayed on the LCD as the keys are pressed. LCD will revert to normal tempera-

ture 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.

OVERRIDE Sets the appropriate output [Sensor or Setpoint] to its lowest resistance value.Output maintains as long as the key is pressed plus a few seconds once released(Only 5-button units)

Specications

POSSIBLE PROBLEMS:

Temperature reading isincorrect

Setpoint reading is incor-rect

POSSIBLE SOLUTIONS:

- Determine that the temperature sensors wires are connected to the correct controller input terminalsand are not loose.

- Check the wires at the sensor and controller for proper connections.- Measure the physical temperature at the temperature sensors location using an accurate temperature

standard. Disconnect the temperature sensor wire (Terminal 1) and measure the temperature sensorsresistance across the sensor output pins with an ohmmeter (Make sure the RuPM is powered for thismeasurement). If the measured resistance is different from the temperature table by more than 5% callBAPI 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.

- Make sure that the setpoint output wiring is correct. Remove the setpoint output wire (Terminal 3) andcheck the output for the correct resistance or voltage output (Make sure the RuPM is powered for thismeasurement). See the product label for your specic range. Dont forget to reconnect the wire.

- Check that the resistance across the override output is less than 5 ohms when the OVERRIDE buttonis pushed (Make sure the RuPM is powered for this measurement). Disconnect the temperature sensorwire (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 measure-

ment). Remove the fan output wire (Terminal 4) and check the output for the correct resistance output.Push the FANSPEED button and check the resistances when each LED is lit. See the Fan Speed sec-

tion (Page3) for your specic output resistances. Dont forget to reconnect the wire.
