VMA16 (16-bit) VAV Modular Assembly controllers are programmable BACnet® Application Specific Controllers (B-ASCs) with RS-485 MS/TP communications. VMA controllers feature an integral 4 N•m damper actuator and differential pressure transducer (DPT) with models for cooling only or cooling with reheat applications and fan control.

Note: These 16-bit models are available for UL 864 10th Edition UUKL/ORD-C100-13 UUKLC Smoke Control System applications.

The differential pressure transducer (DPT) in the VMA16 (16-bit) controllers provides consistent flow readings with minimal drift and requires minimal auto-zero calibration. There are no filters to change, which helps to ensure very close tolerance to published accuracy.

The VMA16 (16-bit) controllers can be configured for single-duct, dual-duct, and supply/exhaust applications. Note that some of these applications may require an additional actuator and DPT.

VMA16 (16-bit) controllers support NS and WRZ Series Communicating Network Sensors for temperature sensing, fan override, and occupancy override control.

Important: You cannot purchase a similar third-party device and install it in a UL/cUL Listed smoke control system. Doing so voids the UL/cUL Smoke Control Listing. Third-party devices must be provided and labeled by the factory as described in the UL/cUL Smoke Control Listing.
Important: Only those Johnson Controls products identified for use in smoke control applications have been tested and listed by UL for use in a Metasys system UL 864 10th Edition UUKL/ORD-C100-13 UUKLC Smoke Control System. Installation of a product that is not UL/cUL Listed and labeled for this application prevents the entire system from being UL/cUL Listed for smoke control.
