Dear all,

I have an HOW-12LB outdoor unit connected to and HSW-9LB indoor unit (this is against manufacturer guidelines, but for the moment this is not the issue).


The system is neither cooling nor heating, and the indoor unit is issuing the following error code:

Operation: 5 blinks
Timer: continuous blinks

If I go to level 2 using the Test button on the remote, the error code changes to the following:

Operation: continuous blinks
Timer: 3 blinks


It seems the problem is with the outdoor unit once I checked the error codes on service manuals for similar Fujitsu Units, but the exact combination wasn't there. I'd really appreciate if somebody could help me out to locate the exact communication error so I can see about fixing it myself. A service manual would be of great help!
