Supply connections must be made using wires rated for 75 c minimum.

Vav box control diagram. Operator to override the vav box control into either normal mode or smoke control mode. Upon fall in space temperature the vav damper will modulate to minimum position. If supply connections are for 250 volts or greater all wiring must be insulated for 600v. Variable air volume vav products when coupled with the patented flowstar airflow sensor enviro tec terminals are among the quietest and most accurate airflow control devices in the industry.

Follow the wiring piping diagram found on the side of the unit or the inside of the electric heater control panel cover. Do not use aluminum conductors. A vav box is integral to the ductwork connecting primary ductwork to secondary ductwork. Model tss terminals provide variable air volume vav control beyond the typical single duct box.

They are specifically designed for precise air delivery throughout the entire operating range regardless of the installed inlet conditions.
