To address a ZS Sensor
Each ZS Sensor on an Rnet must have a unique address, but addresses do not have to be sequential.
Use the DIP switches on the back of the ZS Sensor to set an address from 0 to 14. (0 is factory default.) Each DIP
switch has the value shown in the figure below. Turn on as many DIP switches as you need so that their total value
equals the address.
DIP
Switch
value
1
ON
2
4

1 2 3 4
EXAMPLE
DIP switches 1 and 4 above are on. Their values (1 + 8) total 9, so the sensor's address is 9.

Listing UL: NEC CL2P, or better
To wire and mount a ZS Sensor
PREREQUISITE
The Rnet cable is wired to the controller. The shield wire and the ground wire should be inserted
into the controller's GND terminal.
1 Turn off the controller's power.
2 Pull the backplate off the ZS Sensor. You may need to turn the setscrews in the bottom of the sensor
clockwise until you can remove the backplate.
3 Pull the Rnet communication cable through the slit in the insulated backing material.
3.30 in.
(8.38 cm)
4 Use 2 screws to mount the backplate to the wall or outlet box.
5 Partially cut, then bend and pull off the outer jacket of the Rnet cable(s). Do not nick the inner insulation.

6 Strip about .25 inch (.6 cm) of the inner insulation from each wire.
7 If wiring 1 cable to the ZS 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.

Wiring and mounting a ZS Sensor
8 Insert the other 4 wires into the ZS 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
wire...
Red
Black
White
Green
To this
terminal...
+12V
Rnet-
Rnet+
Gnd
CAUTION
Allow no more than 0.06 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 device may not communicate correctly.
9 Attach the sensor's cover and circuit board to the mounted backplate, inserting the top first.
10 Turn the setscrews one full turn counterclockwise so that the cover cannot be removed.
11 Turn on the controller's power.
NOTE
Use the same polarity throughout the Rnet.

To communicate through the local access port
You can connect to the Local Access port of the ZS Sensor to perform test and balance or to make changes to any
device on the network.
PREREQUISITES
•A computer with a USB port
•A USB Link (Part #USB-L)
CAUTION
If multiple controllers share power but polarity was not maintained when they were wired, the
difference between the controller's ground and the computer's AC power ground could damage the USB Link and
the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link. Purchase a USB isolator online from a third-party manufacturer.
Connect the USB Link to the computer and to the ZS Sensor's Local Access port.

If using a USB isolator, plug the isolator into your computer's USB port, and then plug the USB Link cable
into the isolator.

Troubleshooting
ZS Pro or ZS Pro-F
If display shows...
Then...
Incorrect or missing
values
Check for errors in the i-Vu® application and Snap.
On the control program's
Properties
page, select the
Rnet Points
tab.
Verify that values coming in from the sensors and those going out to the
sensors are expected values.
In the i-Vu® application, double-click the Sensor Binder and ASVI
microblocks to check for problems in the
Status
and/or
Error
columns.
If the
Error
column shows
Resource Allocation
, try formatting the
sensor (page 12). If the error is not corrected by formatting, the control
program engineer should reduce the number of items that the sensor is
trying to display.
Nothing The sensor has no power.
The sensor is not communicating with the network. Check:
•Software/addressing setup
•Wiring connections
•Controller operating status
Characters that
seem out
of place
The sensor may have a memory problem. Try formatting the sensor
(page 12).

Troubleshooting
To format a ZS Sensor
Formatting a sensor clears its flash memory. Do either of the following to format a sensor:
•Download the controller that the sensor is connected to.
•Do the following:
a) Remove the wiring connector from the sensor.
b) Note the current position of the DIP switches.
c) Set all DIP switches to the ON position.
d) Reattach the wiring connector to format.
e) After approximately 3 seconds, remove the wiring connector.
f) Set the DIP switches back to their original position.
g) Reattach the wiring connector.
NOTE
If you move a sensor from one controller to another controller that has a different control program, format
the sensor.
