Help with marine Air Conditioning
Off the wall question. My boat as a two unit AC system, the old unit has a capaliary tube analog thermostat. It has bit the dust. New one is $120, probably only have a couple years of life left in the unit, would prefer to switch to a less expensive digital thermostat. The unit is manufactured by Eastern Marine Corp, sold under the Ocean Breeze name. Anybody know how to change from the 7 wire analog to the 4 wire digital? Because of liability issues the company won't help with the conversion. He did say that Red was common, compressor was yellow, fan was green, heat is Brown. Also have purple, Black and white wires to do something with. Have a couple of pretty worthless wiring diagrams I can share. Don't care if the heat function works, it blows the CB if selected with the old thermostat.

Bad idea. The digitals are MUCH less reliable than the old style thermostats. Lots fail with voltage spikes from shore power to generator switch over. I'm curious why the digital is cheaper. All I've seen were rather expensive to replace.
Btw, I've special ordered my last 2 marine AC units with the dial controls. I've never seen one fail.
