ZS Sensors are thermistor-based temperature sensors that may optionally sense humidity, CO2, or VOC. ZS

Sensors are wired to the Rnet on Open controllers:

The following table shows the 4 ZS Sensor models and their features.

Sensor

Features

ZS Standard

•Local access port

•No user control

ZS Plus

•Slide potentiometer to make the zone warmer or cooler

•button to override the schedule and put the zone in an

occupied state, or force the zone to an unoccupied state

•Green LED to indicate occupied state

•Local access port

What are ZS Sensors?

Sensor

Features

ZS Pro

•LCD display

•button to override the schedule and put the zone in an

occupied state, or force the zone to an unoccupied state

•and buttons to change any editable property, such as

the setpoint temperature

•button to cycle through information defined in the control

program

•Green LED to indicate occupied state

•Local access port

ZS Pro-F

All of the ZS Pro's features plus:

•button to turn on heating, cooling, or fan only, or set to

auto control.

•button to adjust fan speed

•

F/C

button to set temperatures to Fahrenheit or Celsius

To configure the control program for the desired user interaction with the sensor, see the ZS Sensor Application

Guide.

For basic user instructions, see the ZS Sensor User Guide.

Rnet Configuration

An Rnet can consist of the following devices wired in a daisy-chain or star configuration:

•Up to 15 ZS Sensors

•Up to 2 BACview®devices

NOTES

•Although an Rnet can have 15 ZS Sensors, you can have no more than 5 sensors per control program.

•You cannot have SPT sensors and ZS sensors on the same Rnet.

What are ZS Sensors?

Listed by FCC Part 15-Subpart B-Class A, CE

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 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.

Wiring and mounting a ZS Sensor

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

The controller and the external power supply must share a common

ground.
