Zone sensors
You can wire ZS sensors and/or a Wireless Adapter that communicates with wireless sensors to the TV-
MPCXP1628-NR's Rnet port. You can have up to 15 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 162.5 mA when the TV-MPCXP1628-NR is powered from an AC source and
up to 262.5 mA when powered by a DC source. 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 wire an Equipment Touch or TruV u™ ET Display to the TV -MPCXP1628-NR's Rnet port to view or change
the controller's property values, schedule equipment, view trends and alarms, and more, without having to access
the system'
s server. The Rnet can have one Equipment Touch or TruVu™ ET Disp lay, plus ZS sensors and/or a
Wireless Adapter that communicates with wireless sensors.
NOTE These touchscreen devices are not powered by the Rnet.
•

CAUTION A touchscreen device can share a power supply with the Carrier controller as long as:
•
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.
