No need to sense level, as running out of level for even a short time will dramatically raise boiler temperatures. And the temperature is much easier to measure than angle, as with angle you also have to account for acceleration, deceleration, bumps, etc.

At the Seminar Paul gave at an FMCA Convention, he had a test cooling unit set up with his control unit installed on it.

Up on the screen was a temperature monitor he had set up with probe on the refrigerator boiler. He raised one end of the test cooling unit on a 2X4 (so less than 2"). While he talked (less than 5 minutes) we all watched the screen and could see the temperature rising VERY quickly up to the point where the controller turned it off. Then once it cooled down, the controller re-started the cooling unit.

Funny, I installed mine carefully, tested it, followed all directions yet I have NEVER had an alarm for overheat, regardless of angle, etc.
