Hi CommtechinVA,
There is nothing wrong with the UCM.
If the VAVs are connected to Summit, Summit is stopping your override, and returning it to normal operation. Or what it perceives as normal.
If your customer has a work station, go into and check the setup of the UCM at the problem address. Check the Flow Control setting, normally set to Auto.
Check the Zone Sensor temperature, to see if somebody has put offset into the sensor.
Let us know.
Good Luck.
