The above installation has been working with out problems for at least 6 years.

But following a number of electrical outages (trawler /sub-marine cable issues!!) this installation is showing the dreaded comms error message.
Firstly: has anybody got replacement boards available and where?

I do appreciate that Sanyo was bought out by Panasonic.
Silly question but are circuit diagrams and protocol details available.   

final point the red led on the controller board in HP is lit.

Look for ward to a reply

Have you emailed the technical department?

Maybe the best way forward as no one has replied
