    Machine interface advice

    Guys..... thanks for the input. I am not a programmer, but, I have " picked a lot of things up " in life by diving in. This will help me to start out at least with a tool geared to what I am looking for. Thanks again!

    DX VAV CONTROL

    I am assuming we are talking reciprocating compressors here. Seems the first problem is probably the 1 degree "differential" setting. If there are no unloaders on the compressors at lighter loads you are probably beating the compressors to death on starts, not to mention loss of...
