What is DDC ?

Division of Disease Control

Controller, central, and most control units of programmable matter. That is, the program code controls the direct digital significant customization for the intended use. App features include the Timeline, settings, controller, logic, timer, events list and alerts. Units control usually has input, analog and digital, that have the possibility of measuring (temperature, humidity, or pressure) can make and also has the output of the analog and digital for the control of the intermediary transfer (hot and cold water or steam). Digital inputs are usually connection (dry) of the control devices and the input of the analog, usually a voltage, the amount of flow the device size, a receiver, a variable (temperature, humidity, speed, and pressure). Output usually contact, relays that are to operate and stop the equipment, process and output, analog, usually a voltage or signal stream that are to control the movement of control devices the intermediary (water/air/ steam) like the lions, etc. performance and engines goes to work. Groups from the controller, DDC, network, or not, a layer of system make up. This sub-system for and overall performance of the HVAC system is vital. System DDC brain HVAC system. This layer the position of each damper and Valve, can determine. This layer determines which fan. pump and chiller, with what speed or capacity. With this intelligence, programmable in the brain we have to the concept of building automation as we move.
