One last thing, and I don’t know how significant this may be, but the hot water system for the bus is shut off. I was reading an article that stated the hot water circuit should be on in order for the system to work correctly.
My understanding of the reason you "add heat instead of cycling the compressor" is as long as the compressor is running the evaporator coil stays cold and removes moisture from the air (think water dripping under bus). If you cycled the compressor the humidity in the coach could get high causing folks to feel hot even thought the air temperature is correct.Think about our coaches original design and 47 people on the bus talking, breathing, etc and how much moisture they add to the air.I leave my water valves open for that reason I can't stand humidity. With the warm air mixing with the cold you get the temperature you want, keep the air moving, and keep the humidity down.I understand I am going overboard but I hope this helps anyone who was wondering why.Best,Justin
So, The two things I learned is I am way more sensitive to humidity than most people and I should close the water valves on my bus.
