The DDC based control DB typically includes a central control unit, which is responsible for collecting data from various sensors and devices, making decisions about when to turn equipment on and off, and adjusting various parameters to maintain the desired indoor environment.

The DB also includes input and output (I/O) devices, such as temperature sensors, humidity sensors, and other devices that are used to interface with the building systems. The panel also includes a user interface, such as a touch screen or web interface, that can be used by building operators to monitor and control the building systems.

The DDC based control DB allows for a high level of automation, which can improve the efficiency, safety, and comfort of the building. It also allows for advanced control strategies, and can also be integrated with other building systems, such as security systems and fire alarms, for a more comprehensive building management solution.

In summary, a DDC based control Distribution Board (DB) also known as a Building Management System (BMS) is an electrical device used to control and monitor the operation of various building systems, such as heating, ventilation, air conditioning, lighting, and security. It typically includes.
