KMC Controls BAC-9000A Series BACnet VAV Controller-Actuators (B-BC)

DESCRIPTION

KMC Conquest™ BAC-9000A series controller-actuators are designed to operate VAV (Variable Air Volume) terminal units. The integrated alarming, scheduling, and trending enable these BACnet Building Controllers to be powerful edge devices for the modern smart building ecosystem.

With integrated actuators, internal air pressure sensors, and other powerful features, they are ideal for new installations and upgrades of less-efficient equipment. They easily mount to terminal boxes by securing a “V” clamp on the shaft and securing a single-screw anti-rotation bracket.

The factory-supplied programming covers common VAV applications. The controllers feature simple, menu-driven setup choices using an STE-9000 series digital sensor, which can be installed permanently as the room sensor or used temporarily as a technician's service tool.

Alternately, quick configuration of controller properties can be done using NFC (Near Field Communication) from a smart phone, tablet, or computer (using KMC Connect Lite™ app) while the controller is unpowered. For demanding building automation custom requirements, these controllers are also fully programmable. Custom configuration and programming, with wizards for application programming selection/configuration, are enabled by KMC Connect™ software and the KMC Converge™ module for Niagara Workbench.

KMC Converge and TotalControl™ software additionally provide the capability of creating custom graphical web pages (hosted on a remote web server) to use as a custom user-interface for the controllers.

APPLICATIONS

Application options include:

• Pressure independent or dependent VAV
• Cooling only and with changeover
• Staged, modulated, floating, or time-proportional reheat
• Series or parallel fan control
• Dual duct (with TSP-8003 actuators)
• CAV (Constant Air Volume)

For installations with a BACnet building automation system, these easily integrated controllers signal demands for higher static duct pressure, cooler or warmer supply air, and other diagnostics for AHU optimization. (See also Sample Installation on page 6.)
