Tank heater switch turns on the holding tank pad heaters. Used in cold weather camping.
Hi limit switches. Used to control or shut down when water in the tank reaches preset temp. Dont want 200 degree hot water now do we.
Dont worry, it gets easier. I spent hours with a lable maker marking everything when we first got our creek in 2005. Since then I have added about 4 more things to the panel.
