8.2 Building Control System Introduction
High-speed transmission type air-conditioning control system D-BACS (DAIKIN Building Air-conditioning Control
System) networks up to 64 groups of indoor units (128 units). There is a complete line up of variegated control
equipment for D-BACS, such as parallel interface, or a master station that can directly access a building control
computer via a communication line. Changing control function to a component configuration makes D-BACS a central
control system that can be flexibly combined with other equipment, which can respond to various air-conditioning control
needs such as application, conditions and scale.
