Zone sensors
You can wire ZS sensors and/or a Wireless Adapter that communicates with wireless sensors to the TV-VVTZC-E2's
Rnet port. You can have up to 10 ZS and/or wireless sensors.
NOTES
•
A control program can use no more than 5 ZS sensors, so you must use multiple control programs if your
Rnet network has more than 5 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 I
nstallation
and Start-up Guide
to determine the power required.
Touchscreen devices
You can connect the TV-VVTZC-E2 to the touchscreen devices using the Rnet port or one of the Comm/Service
ports.
Rnet port
You can wire an Equipment Touch or TruVu™ ET Display to the TV

ve one Equipment Touch or TruVu™ ET Display, plus ZS sensors and/or a
Wireless Adapter that communicates with wireless sensors.

system's server.
NOTES
•
These touchscreen devices are not powered by the USB port.
•
The TruVu™ ET Display requires a 24 Vdc external power source.
CAUTION
A touchscreen device can share a power supply with the Carrier controller if:
•
The power source shared by the controller and Equipment Touch is AC power.
•
The power source shared by the controller and TruVu™ ET Display is DC power.
•
You maintain the same polarity.
•
You use the power source only for Carrier controllers.
