I have a church that we do pm and service on and recently, I ran into a issue with a Tracer mp580/mp581 panel. The church has a override button on the wall so when they have a function that's not on the schedule, they can override the system to occ without going into the panel.
That leads me to my problem. I have two ahu's with dx cooilng. When the override button is hit, only one of the ahu/cond enables to occ. But if I go into the override menu on the user interface, I can override the entire system one component at a time. Why won't the override button bring both ahu's up to run. This system has been in place for 5 years and never had this problem before. Thanks for any help anyone can provide.
And yes I did call tech support at my local Trane commercial office. But it seems like everytime I call for something over there, they are never at the phone. Kinda of hard to solve a problem in the field when tech support doesn't exist half the time. And when and if they do call, it's never when i'm on site.
