A Building Management System (BMS) Control System is a computer-based system that is used to monitor and control the mechanical, electrical, and other systems within a building. This system can be used to control heating, ventilation, air conditioning, lighting, security, and other systems within a building. It is designed to provide a centralized point of control for all of the systems within a building, allowing for greater efficiency and cost savings. BMS Control Systems can be used to automate certain processes, such as turning off lights when they are not in use, or adjusting the temperature in a room based on the occupancy. The system can also be used to monitor energy usage and alert personnel when energy levels are too high or too low. BMS Control Systems are becoming increasingly popular in commercial and industrial buildings, as they provide a great way to save energy and money.
