What are ZS sensors?

Rnet configuration

You can use the Wireless sensors, ZS sensors, and an Equipment Touch on the same Rnet. The number of

sensors you can use on a controller's Rnet depends on how many control programs it can have. If the controller

supports:

•Only one control program, the Rnet can consist of:

•Up to 5 ZS sensors

•One Wireless Adapter supporting up to 5 wireless sensors

•One Equipment Touch

NOTE

You can have any combination of ZS and wireless sensors, but no more than 5 sensors total.

•Multiple control programs, the Rnet can consist of:

•Up to 15 ZS sensors

•One Wireless Adapter supporting up to 15 wireless sensors

•One Equipment Touch

NOTES

•You can have any combination of ZS and wireless sensors, but no more than 15 sensors total.

•You can have no more than 5 sensors per control program.

WARNING

Using Rnet tags 5, 6, or 7 in a control program that has a ZS Pro or Pro-F version 3.4.02 or earlier in a Sensor

Binder microblock will disable the display on the ZS sensor. You must do one of the following to prevent this

occurrence:

•Replace the ZS Pro or Pro-F with a newer one (v03.05.02 or later).

•If the controller supports multiple control programs, create a separate control program for the ZS Pro without

tags 5, 6, or 7.

To determine the ZS Pro or Pro-F version, in the i-Vu®

Installer

tree, expand the controller with the ZS Sensor, and

then select the Sensor Binder microblock. The version is shown in the

Associated Sensors

table.

CAUTIONS

•You cannot have SPT Sensors on the same Rnet with any of the above devices.

•An Rnet can have more than one wireless Pro-F sensor, however, changing the setpoint on one Pro-F will not

be reflected on the display of another Pro or Pro-F, possibly causing confusion for the user.

additional power, use an external power supply. Use the above power requirements to

calculate the size of the external power supply. The controller and the external power

supply must share a common ground.

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.

NOTE

Dropping a sensor can upset the calibration, and it may require 21 days to return to our stated accuracy.

Motion sensor installation

The motion sensor on a ZS Pro needs to have a direct line of sight to the occupants in the room.

If the size of the room exceeds the maximum detector range, use multiple sensors to adequately monitor the area.

Avoid placing the sensor:

•In a location that has a direct line of sight through an open door to a hallway where the sensor could detect

movement of people in the hallway.

•Near air ducts. Rapidly changing air currents from the air ducts could lead to false sensor readings.

ZS zone sensors

To address a ZS zone 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 zone 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 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.

To wire and mount a ZS zone sensor

The Rnet communicates at a rate of 115 kbps and should be wired in a daisy-chain, star, or hybrid configuration.

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.

5 Strip about .25 inch (.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:

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.

ZS zone sensors

To communicate through the local access port

You can connect to the Local Access port of a ZS zone 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.

NOTE

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

Troubleshooting a 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.

Effective setpoints fields These fields display the effective setpoint values. They can display a maximum value

of 99 or 99.5 if the

Edit Increment

is set to 0.5. If the effective setpoint exceeds this

maximum value or if the

Edit Increment

is set to 0.1, the value will flash.

TIP

If you need an Edit Increment of 0.1, put the effective setpoints on the

Information screen in the Primary Value field. Hide the effective setpoints on the

Home screen by selecting

Sensor Setpoint Adjust Option 4

on the

BACnet Setpoint

microblock's

Rnet

tab.
