    Alerton DDC file

    Does anyone have any VLC DDC files for a central plant with heat pump water loop, cooling towers, and boilers. Two loop pumps and one tower pump. Or do I have to write/draw the DDC from scratch?

    Alerton plant DDC is pretty much always done from scratch because plants vary to much from job to job. Plants can be a bit difficult too. Timing problems can cause things to explode. I prefer the standalone stuff that we can just give an on/off signal and let the embedded 3rd party stuff handle all the valves and whatnot. I'd suggest a lot of safety algorithms and running your timings by someone with a lot of experience, even if they don't have an Alerton background, they may be able to help.
