Have a 2001 centravac, UCP2, that I would like to optimize. It is capable of handling below 60 degree water. There are no BAS controls in bldg. other than a time clock. I would like to reset based on OA wetbulb plus tower approach but do not want to add a complete BAS to get there.
I've done something similar with just one control module and a display that connects directly to the control module. I don't think you will find anything "out of the box" that will do what your wanting. The best bet is to call your favorite controls company, they should be able to do what your wanting fairly painlessly.

I would add some kind of small PLC with a display or with a display you could tie in to adjust as needed as X is saying.
The other option is depending on the drive you 'may' be able to utilize the drive's added inputs and logic to do this.
