G'day, mate. A specialized electrical
relay isntalled in the a/c circuit that can be activiated remotely will do the trick. A good electrical
contractor in your area should be able to get you set up. I'm always a little nervous having these kind of systems running when I'm not on the boat
. A/C units and fridge/freezers can have cooling
pumps that can quickly flood the boat, should say, a hose come off. All the best. Cheers.
