    York VCIV 2 compressor chiller

    Good morning,

    Working on a chiller system control project. Looking to integrate the ddc control panel into the chiller system via a hard wire. I have poured over the wiring schematics and from the looks of things this is not possible. Does anyone have any experience with this.

    thanks in advance

    Explain hard wired ?

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    Enable & disable thats all you need to do the Chiller will do the rest (Really)

    After a while you realize that while you are getting
    dirty, the pig is actually enjoying it.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    There is alot of hard wire capabilities with this chiller. You need to be more specific about what you , would like to do . ? do you want to reset setpoints , see the status of systems , or alarms . turn on pumps using the outputs . or just turn on individual systems. form 201.23.nm2 (608) part number 035-21506-101 pages 80 and 81 has alot of information on it. I don't know what form you are looking at but look very closely at the electrical diagram section.
    the YCIV 's are alot alike.

    Hello,
    I have the panel schematic drawn up.. I am setting up the ability to start/stop the chiller..... I am using the wiring diagram that you mentioned. But it looks like there aren't any terminals where i can wire in my remote start/stop.... There is run permissive but that looks like it is part of a safety circuit tied in with the flow switch... all set up in series (and configuration) I have the pump request, chiller run, alarm, remote modulation so thats not an issue...

    Oh by the way thanks

    Use the run permissive to enable each system (compressor) !

    Why make it more complicated. York56 is right.
