CO2 sensor installation
IMPORTANT Do not install ZS CO2sensors in continuous occupancy applications. For a ZS CO2sensor to
maintain accuracy, it must be installed only in a zone that is unoccupied for at least 4 hours a day with enough air
movement during the unoccupied period to return CO2to background levels.
A ZS sensor with CO2uses Automatic Background Calibration which waits for the lowest value in a 24-hour period
that deviates no more than 40PPM for at least 15 minutes, and assigns that value to the 400PPM baseline. This
daily Automatic Background Calibration may take up to 21 days to fully calibrate the sensor.
After installation, a ZS sensor with CO2must be powered up for one hour before it attains accurate readings.
NOTE Dropping a sensor can upset the calibration, and it may require 21 days to return to our stated accuracy.
Rnet Configuration
An Rnet can consist of the following devices wired in a daisy-chain configuration:
•Up to 15 ZS Sensors
NOTE You cannot have more than 5 sensors per control program
•Up to 5 ZS sensors and 1 Equipment Touch device
NOTE You cannot have SPT sensors and ZS sensors on the same Rnet.
Rnet wiring specifications
NOTE Use the specified type of wire and cable for maximum signal integrity.
Description
4 conductor, shielded or unshielded, CMP, plenum rated cable
Conductor
22 AWG (7x0096) bare copper
Maximum length
500 feet (152 meters)

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. (1 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
8
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.

CAUTION Do not share power between controller's power and external 12 Vdc unless both devices are half
wave.

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.
Partially cut, then bend and pull off the outer jacket of the Rnet cable(s). Do not nick the inner insulation.

Foil shield
.25 in.
(.6 cm)
Shie ld wire
5 Strip about 0.25 inch (0.6 cm) of the inner insulation from each wire.
6 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.

7 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:

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.
8 Attach the sensor's cover and circuit board to the mounted backplate, inserting the top first.
9 Turn the setscrews one full turn counterclockwise so that the cover cannot be removed.
10 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.

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. 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.

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.
