ZS Series RNet Sensor Overview

The ZS Series line of intelligent zone sensors provides the

function and flexibility you need to manage the conditions

important to the comfort and productivity of the zone

occupants. The ZS sensors are available in a variety of

zone sensing combinations to address your application

needs. These combinations include temperature, relative

humidity, and indoor air quality (carbon dioxide or VOCs

(Volatile Organic Compounds)). They are built to be

flexible allowing for easy customization of what the user/

technician sees. Designed to work with the Aurora UPC

controllers the ZS sensor line includes the ZS Base, ZS

Plus, ZS Pro and ZS Pro-F.

The UPC uses a proprietary communication called Rnet

to receive the space temperature from the zone sensor.

This is done using (2) 18 AWG twisted pair unshielded

cables for a total of 4 wires connected to the Rnet port.

The sensor gets its power from the UPC controller and

connecting multiple sensors to one UPC will allow for space

temperature averaging. The UPC can support one ZS Pro

or ZS Pro F with up to four ZS standard sensors wired to

the Rnet port on the UPC for a total of 5 zone sensors.

The sensors use a precise 10k ohm thermistor with less

than 0.18°F drift over a ten year span, this allows for less

maintenance or re-calibration after installation. The sensors

also have a hidden communication port for connecting

a BACview or local laptop that provides access to the

equipment for commissioning and maintenance. The table

below shows the features of each of the four sensors that

are currently available.
