Wiring devices to the VAV Zone II's Rnet port
The Rnet communicates at a rate of 115 kbps and should be wired in a daisy-chain or hybrid configuration.
Supports up to

5 wireless and/or ZS sensors

One Equipment Touch

One TruVu™ ET Display
For more detailed instructions, see the device's Installation Guide.
CAUTION Rnet power
The Rnet port provides 12 Vdc/200 mA* maximum at 32°F (25°C). that can be used to power zone sensors. If
the total power required by the sensors on the Rnet exceeds the power supplied by the port, use an external
power supply. See the sensor's Installation and Start-up Guide to determine the power required.
* These numbers will be reduced at higher temperatures.
Wiring specifications
Cable from sensor to controller: If <100 ft (30.5 meters) 22 AWG, unshielded
If >100 ft (30.5 meters) 22 AWG, shielded
Maximum length: 500 feet (152 meters)
To wire ZS sensors to the controller
ZS Sensors are thermistor-based temperature sensors that may optionally sense humidity, CO
2
, or VOC. ZS
Sensors are wired to the Rnet port on i-Vu® Open controllers.
You can use the following ZS sensors:

ZS Standard

ZS Plus

ZS Pro
NOTE The ZS CO2 model uses 190 mA during sample period. Use auxiliary 12 Vdc, unless it is the only device on
the Rnet port.
