The VAV Zone II Secondary Duct receives power from the Zone Ctrl II. Increase the
controller's power supply by 3 VA when connecting a VAV Zone II Secondary Duct.
Actuator
Belimo brushless DC motor, torque 45 inch-pounds (5 Nm), runtime 154 seconds
Act Net port
To connect the actuator to the VAV Zone II Secondary Duct controller and to the
Zone Ctrl II
Protection
Built-in surge and transient protection for power and communications in
compliance with EN61000-6-1.
Status indicators
LEDs indicate status of communications, running, power, and motor direction
Environmental operating
range
32 to 130°F (0 to 54.4°C), 10–90% relative humidity, non-condensing
Integral airflow sensor
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 ±5% of full flow at 2
in. H2O.
