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.
