A/C issues

rasbury

We have a 270, 2005 with low hours. we have the A/C- but don't use this a lot as we are just getting things caught up on the boat to where we can stay out so we have only done the overnight thing maybe 5~6 times in our first year....the a/c thermostat does not seem to be working as it should but there are some differences I know from a house hold type unit- if I set it all the way as low as it will go it will keep the boat cabin "comfortable". If I try to set it say at 70 or 72, it seems to flip to heat so it becomes cooler outside than in, even in the am. I read there is a cycle it will go through to defrost the coil if it is freezing up but I don't think it ever got that cold. Like wise, the one night we used the heat I had to shut if off as it was roasting us. I have no error messages or anything on the thermostat and I have the manuals but there is not a lot of trouble shooting information on it.....any ideas? I looked at the cooling unit and it does not seem to be crudded up or anything.....the boat has only 110 hours or so on it now....

See my response in your other post.

You need to program it,,,forget reverse/ heat cool mode choose cool only for summer.
