Siemens Apogee DDC Controller

BAS DDC Learning | HVAC - HVAC Building Automation Systems (BAS) or Direct Digital Controls (DDC) is pretty much one and the same. Basically described BAS and DDC are combining air conditioning, heating, ventilation, lighting, electrical loads, security systems, and life and safety systems to a computer and complex algorithms for better control over the systems.

HVAC Control DDC Programming Logic 3

DDC Programming Logic 3DDC Programming Logic 3 - DDC control logic blocks have practically an unlimited way of arranging the blocks for HVAC control. Below is an example of a line of logic blocks arranged for static pressure control of a VAV air handler supply fan using a variable frequency drive. This same arrangement could also be used for static pressure control using a bypass damper instead of a VFD. (more…)
