    JCI BACnet

    I've got a co-worker working with JCI BACnet and is having a problem. The system is controlling humidity on an air handler, and the setpoint is 35%. He can go in and change the setpoint from the graphics to lets say 50%, and at random times, the setpoint changes back to 35%, He's also went in and changed the default value to 50%, and the problem still persist. Anyone have an idea of whats causing this? He wants me to go in and take a look, but the JAVA app has taken almost an hour to download remotely. Just figured I'd hit the forum up for some insight. Thanks!

    I have a feeling that people are going to have to know exactly what model these controllers are in order to offer suggestions.

    I got it figured out. It was a damn reset schedule. These were FEC's by the way.

    There is another patch past the 4.1.0.45. The latest version brings it up to 4.1.2.09
