Rnet port
•
Supports up to 10 wireless and/or ZS sensors, and one Equipment Touch or
TruVu™ ET Display
•
Supplies 12 Vdc/260 mA power to the Rnet across its rated temperature
range.
NOTE Ambient temperature and power source fluctuations exceeding the
listed operating ranges may reduce the power supplied by the Rnet port.
NOTE
If the total power required by the sensors on the Rnet exceeds the power
supplied by the Rnet port, use an external power source. The Wireless Adapter,
Equipment Touch, or TruVu™ ET Display must be powered by an external pow
er
source. See the specifications in each device's Installation and Start-up Guide to
determine the power required.
Act Net port
Supports a combination of up to 5 Act Net addresses. Act Net devices must be
addressed as follows:
○
Address
1
is reserved
for the built-in actuator
○
Address
2
and
3
are reserved for the VAV Zone II Secondary Duct
○
Address
4
and
5
for i-Vu® Smart Valves
Maximum power available for Act Net devices:
•
AC supply - 25 VA (1 A)
•
DC supply - 15W (0.625A)
•
Use an external transformer if your devices exceed the maximum power.
Comm/Service ports
USB 2.0 host ports for setting up the controller and troubleshooting through a local
connection to a computer, connecting to the TruVu™ ET Display, or the Carrier
wireless service adapter.
