If there are any Summit experts out there I have a question.
I have an office building with 13 water cooled self contained Trane units. I believe the Summit is Version 11.
Every once in a while I will get a service call for no cooling on one of these units. When I get there there is a "0C" message at the display on the UCM.
When I go back to the PC go to the tree and pull up this unit I find the compressors have not been enabled. When I enable the compressors they stage on pretty quickly.
I believe the facilites people when they tell me they did not change the config. The new facility guy is totally unfamiliar with Summit.
Anybody else seen this happen? It has happened to me 3 times in the last 1 1/2 yr.
Any help greatly appreciated.
