I have two Marine Air Systems units. The forward unit is 7K and functions perfectly. The stern unit is 16K also functions perfectly, except when I start it up. After a few seconds the digital control gives an HHH code. I shut it wait 2-3 minutes, start again and it will run all day. It will cycle on and off as the temperature settings require and function perfectly. It runs cold,and cycles. If I turn the unit off and then back on it is fine. Both units run off the same raw water pump and the filter basket is clean. The mystery unit is a split unit model CSP-16K..
I have spoken to their tech service dept. They think it is a wire issue but I don't see how a wire would fix it self when you turn it on a second time.
I thought it might be the high pressure switch, but if it cycles and runs continuously after the initial try I would think that the high pressure switch is functioning.
I would appreciate some help
Thanks
