    Alerton Visual Logic Question

    Does anyone have and can send me PDF's on Visual Logic programming and possibly a Users Manual?
    I've got a job that has a BV (Binary Variable?) that's sent to all the parallel fan VAV box controllers. It is turning on all the fans even though the boxes are at 100% cooling demand. This is mixing the primary air (55*) with the heating air (return air) and providing 65* air causing the zones to overheat. (At least it's not turning on the electric heat also)
    Someone obviously got confused between series and parallel boxes.
    I see in the Visual Logic VAV file where the BV "input" is, but do not know how to find where it comes from, or change it and the program.
    If I remove the BV from the fan input of the VAV controllers, would it revert to proper canned fan operation?
    Sorry, I do not have any version or model numbers yet.
    TIA

    Hi jogas,
    It should be in your inbox. Let me know if you didn't get it. I'm having some email issues.
