The VAV-4040 variable air volume/variable volume and temperature controller features an integrated Belimo® damper actuator and is said to provide cost-effective control for a wide variety of VAV and VVT applications. The controller can be used on single-duct or dual-duct VAV boxes, which have a reheat fan, or boxes that have built-in staged or modulating heat. The VVT mode allows the damper output to reverse action in response to the air temperature being supplied by an HVAC unit. The controller can accommodate a tri-state or 2- to 10-V d.c. external damper actuator and offers one output point for open programming. Novar Controls Corporation
