Curious, our ‘17 Windsport 29M has the stick-on holding tank heaters, I had “assumed” they were auto temp controlled as there is no switches on the monitor panel for them. I opened the panel for an unrelated reason (the 3 tank monitors suddenly stopped working) and found wiring coiled up and not connected to anything??? In talking to Thor support about the level monitors the rep seemed a lil confused that I did not have heater control switches in my panel..??!
Well, next week we’ll be at the factory for a few relatively minor fixes at the end of the warranty so this is just another question for them..
