Next year is nice Bob…But this year or even now would be better… 

Mermaid uses that control & posts a PDF link to the manual which has a good wiring digram…

Did the FX-1 not come with a manual with diagram ?

"Do you have any ideas on what needs to be bypassed or changed?"

No Bob I don't have a clue as to any modification that needs to be done…

My thinking is that you either have it wired incorrectly, or that the FX-1 has a bad compressor triac, or relay that is stuck in the closed position.

From what I remember…Luneair was not much different than Cruisair…

But wait a minute now that I think of it….(and this should cost you the $200 bucks you may of saved by not buying a control from me)…In that unit's electrical box, is there a black solid state relay with 4 screw terminals ?…And I don''t mean the start relay that is connected to the black start capacitor…

If so…It will need to be eliminated or at least bypassed…

Steve,

Yes, there is down in the right hand corner. I'm guessing it must still be "hot" which is why I hear the unit kick on when I turn the breaker back on.

Would you disconnect all four wires and tie the legs on each side of the relay together to complete the circuit?

Not quite as simple as that Bob…Looking at the relay right side up (meaning the printed text is upright) I believe the top two connections are left side is Line from main power source, right side is compressor load (feeding the compressor)…The bottom two are: left side neutral & right side is Line trigger from the old control (this closes the relay terminals up top…

Thing is…Those solid state relays will close with very little voltage…Or stay closed if a resistor is not placed across those terminals…It could also be that the relay has failed in the closed position and that was what was wrong with your old control…. 

You would want to connect the top right wire (compressor load) to the FX-1 Board terminal labeled Comp L1…However you accomplish that is up to you… 

It's too late now but would the retro fit panel kits you sell work with the Luneair?

Any of our controls can be adapted to any unit…I have put them on houses too…They are more expensive than the FX-1…But you don't get "Me" with them   

There are some guys on the Trojan forum who have the same setup and I'm happy to send them your way if you think it's more "plug and play" the FX-1 setup.
