    If you need to get them out of danger right away, 75° with a chilled water setpoint of 42° is a safe place to start. Most places I've been to ramp both fans with the same signal.

    By design tag I meant a sticker, usually hand written design specs.

    If you post the serial number there are many techs on here that can get the design info in a few clicks of a keyboard ....
    But then we will start that whole debate about salesguys rushing over to steal work blah blah blah ......

    I have a good friend who worked for trane Los Angeles. I asked him about that and he started laughing at me, I didn’t believe it anyways. Even if the salesman did go, I’m confident in my work....plus every other contractor goes after every account anyways...

    Does the chiller have a refrigerant pump? If so, you can run the tower water pretty cold. Down to 15 degrees above chilled water. You don’t want to run condenser water above design temp but you can run it below design temp. If you have an AFD, you won’t get the full benefit of it unless you have tower relief.

    Yea, thats what I meant by tag. Unfortunately at this site the tower fans are not on drives, simple on/off.
