Rnet Configuration
You wire SPT sensors to a controller's Rnet port. An Rnet can consist of any of the following combinations of
devices wired in a daisy-chain or hybrid configuration:
•1 SPT Plus, SPT Pro, or SPT Pro Plus
•1–4 SPT Standards
•1–4 SPT Standards, and 1 SPT Plus SPT Pro, or SPT Pro Plus
•Any of the above combinations, plus up to 2 BACview6's but no more than 6 devices total
NOTE You must set addresses only on the following Rnet devices:
•SPT Standard sensors if you have more than one on the Rnet. See To address an SPT Standard sensor
(page 5).
•BACview6's if you have two on the Rnet. See the BACview Installation and User Guide.
To address an SPT Standard sensor
If the Rnet has multiple SPT Standard sensors, the first sensor retains its default address of 1. You must give
each additional SPT Standard a unique address on the Rnet. To set the address:
1 Pull the back plate off the sensor, pulling from the bottom first.
2 Remove the two hexagonal screws that attach the circuit board to the cover plate.
3 Remove the cover plate.
4 On the circuit board, set the address jumper to 2, 3, or 4.
5 Attach the circuit board to the cover plate with the hexagonal screws.
Rnet wiring specifications
NOTE Use the specified type of wire and cable for maximum signal integrity.

Listing UL: NEC CL2P, or better
Mounting location
Mount the sensor:
•In an area representing the average temperature in the space
•On an interior wall
•Approximately 5 feet (1.5 meters) from the floor, or as required by local code
•At least 4 feet (1.2 meters) from any corner
•At least 2 feet (.6 meter) from an open doorway
Do not mount the sensor:
•In drafty locations such as near air conditioning or heating ducts, or near open windows
•Over heat sources such as baseboard heaters, radiators, directly above wall-mounted lighting dimmers,
or in direct sunlight
NOTE The sensor mounting plate accommodates the NEMA standard 4x2-in. electrical box. However, the
sensor can be mounted directly on the wall surface if local codes permit.
To wire and mount the SPT sensor
NOTE The sensor mounting plate accommodates the NEMA standard 4x2-in. electrical box. However, the
sensor can be mounted directly on the wall surface if local codes permit.
1 Remove the mounting plate from the SPT sensor. You may need to turn the setscrew in the bottom of the
sensor clockwise until you can remove the mounting plate.
2 Pull the Rnet communication cable through the wire guide in the mounting plate.

5 If wiring 1 cable to the SPT sensor, cut the shield wire off at the outer jacket, then wrap the cable with
tape at the outer jacket to cover the end of the shield wire.
If wiring 2 cables in a daisy-chain configuration, twist together the shield wires, then wrap the shield
wires with tape.
6 Insert the other 4 wires into the sensor's screw terminal connector. If wiring 2 cables, insert like-colored
wires into each terminal.
Carrier recommends that you use the
following Rnet wiring scheme:
Connect this

CAUTION Allow no more than .06 inch (1.5 mm) bare communication wire to protrude. If bare
communication wire contacts the cable's foil shield, shield wire, or a metal surface other than the
terminal block, the sensor may not communicate correctly.
7 Attach the sensor's cover and circuit board to the mounting plate, inserting the top first.
8 Turn the setscrew one full turn counterclockwise to secure the cover to the mounting plate.
9 Wire the sensor to the Open controller. See the controller's Installation and Startup Guide for details.

All SPT sensors
Feature
Usage
Local Access port
See To communicate through the Local Access port (page 10).
SPT Plus
Feature
Usage
Slide potentiometer
Move the potentiometer to raise or lower the zone's setpoint. The maximum you
can adjust the setpoint is defined in the
Max Adjust
field*.
MANUAL ON button
Press this button one time to override the schedule and set the zone to occupied
for the amount of time defined in the
Each pulse
field*. Press the button again
to incrementally increase the time. For example, if the
Each pulse
field is set at
five minutes, press the button once for an occupancy of five minutes, twice for
ten minutes, and so on. The maximum length of time you can override the
schedule is defined in the
Max Accum
field*.
To cancel the override, hold down the
MANUAL ON
button until the
OCCUPIED
LED turns off.
OCCUPIED LED
The LED lights when the zone is occupied from a regular schedule or a manual
override.
*See To change sensor properties (page 9).
SPT Pro
Feature
Usage
Display
The display shows occupancy, zone temperature, and an alarm bell icon. Celsius
values are to the nearest 0.5 degree; Fahrenheit values are to the nearest full
degree.
The display shows
Occupied
when the zone is occupied from a regular schedule
or from a manual override.
MANUAL ON button
Press one time to override the schedule and set the zone to occupied for the
amount of time defined in the
Each pulse
field*. Press button again to
incrementally increase the time. For example, if the
Each pulse
field is set at five
minutes, press the button once for an occupancy of five minutes, twice for ten
minutes, and so on. The maximum length of time you can override the schedule
is defined in the
Max Accum
field*.
The display shows the duration of the override in minutes. If the override time
exceeds 199 minutes, the display shows the time in hours.
To cancel the override, hold the button down until
0
displays. Wait five seconds
for the display to show the current zone temperature again.

Carrier Sensors 9
Feature
Usage
WARMER and COOLER
buttons
To raise or lower the zone's setpoint:
1 Press either button to display the current average setpoint (the average
between the heating and cooling setpoints).
2 Press either button again to raise or lower the setpoint. You can adjust the
setpoint by no more than the amount defined in the
Max Adjust
field*.
NOTE
Pressing either button overrides an unoccupied schedule and sets the
zone to occupied for the amount of time defined in the
Each pulse
field*.
