What does F0045 interrupted 2 timeout fault mean?

The communication internal to the CCU board has an issue

Product line:
PV100S, PV225S, GTxxx


Inside the CCU there is a watch dog chip. It monitor tasks and required time to complete. If the task was not done in time for any reason (took too long, power interruption...etc.) then the unit will fault on 0045.

1. You can try to clear the fault with the F1 button.
2. If pressing F1 button does not clear the fault then try to cycle AC power.
3. If that does not clear the fault then call 866-519-1470 option 3 & 3 to open a new case so that our FSE can go out and replace the CCU board.
