Each is set with the snowflake symbol. Does cool for a while. Floor heat is separate and control is off.

If you're on snowflake, then you're just trying to cool. That's great because it eliminates some other things. When the compressor shuts off for the first time, is it because it reached its target temperature? 

Then it will not "restart"?

Does it happen on all 4 zones? Does it cycle on/off/on if you only have 2 zones running?

I agree with @Richard and first check the probe.

On the bluetooth.... it's marginal at best. It seems to time out instantly if your phone goes to sleep. You downloaded the EasytouchRV and tried to connect through it and the directions, right? Mine had problems in the beginning, IIRC. I rebooted my phone, deleted the current device(which I had so thoughtfully named "newell"), then added it back again after cycling all of the power to the bus(shore, house, and chassis). Believe it or not, this solved the connection issue and the AH floor heat issue. Since then it's been ok, but I just noticed today when I went to take some pictures that the AH Floor heat wasn't working again. Since I have the bathroom tile all ripped out, I may have inadvertently disconnected something. I did grab some pictures of the screens so it would be fresh on my mind.
