Zone Sensors; Touchscreen Devices - Carrier TruVu UC253-V Installation And Startup Manual

What is the TV-UC253-V?

Zone sensors

You can wire ZS sensors and/or a Wireless Adapter that communicates with wireless sensors to the TV-UC253-V's
Rnet port. You can have up to 5 ZS and/or wireless sensors.
NOTES
•
One control program can use no more than 5 ZS sensors.
•
ZS and wireless sensors can share the Rnet with an Equipment Touch or TruVu™ ET Display.
CAUTION Rnet power
The Rnet port provides 12 Vdc at up to 260 mA. When determining which devices to put on the Rnet, verify that
the total current draw of the sensors does not exceed the controller's Rnet power. See the sensor's Installation
and Start-up Guide to determine the power required.
