With a thermostat that works fine in another part of the boat, the system in question does not call for the compressor or the seawater pump when in the cooling mode.

I am going to be ringing out wires to see if there is a discontinuity that is causing the trouble.

I was hoping that perhaps someone on the forum would be able to tell me that the problem must be with wire 'X' which calls for cooling from the thermostat.

Can anyone tell me which wires on that thermostat provide what function?

Thanks,

Its in your Hatteras wiring diagrams. I had mine out last when I wired the FX1.
