TruVu™ VVTBP-E2
Installation and Start-up Guide
•
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 power
source. See the specifications in each device's Installation and Start-up Guide to
determine the power required.
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.
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.

Inputs are configurable in the control program for 0–5 Vdc, 0–10 Vdc, thermistor,
dry contact, or pulse counter.
12 bit A/D
10 pulses per second. Minimum pulse width (on or off time) required for each
pulse is 50 msec.
2 analog outputs, 0–10 Vdc
Configurable as 12 Vdc pulse width modulated (PWM) control signal.
One bank of 3 N.O. binary outputs. Each relay contact rated at 3.75 A max. @ 30
Vac/Vdc. Each bank is limited to Class 2 requirements of 100 VA / 4.2 A.
Configured normally open.
See Output values (page 30).
12 bit D/A
Precision differential pressure sensor 0–2 in. H2O, sensitive down to ±0.001 in.
H2O. Barbed tapered airflow connections accept 3/16 in. (4.75 mm) I.D. tubing.
Allows for readings across the 0–2 in. H2O range, accurate to ±3% of sensor
reading at 2 in. H2O.
32-bit ARM Cortex-A8, 600MHz, processor with multi-level cache memory
