I have recently ran across a Trane RTAC255 with the CH530 Dynaview display. The initial call was for a display lockup. When running for a while the display will "freeze" but when online with techview 14.0 you can see the processor actually running. I change the Dynaview and loaded the appropriate software and watched it run for an hour or so while I CHANGED A FLOW SWITCH. A week later the problem has returned on the new module. All devices appear to be properly bound in binding view, so has anybody ran into this one before?
