I know that this is a pretty stupid question but I have to ask. Every thing is running cool now and I'm starting on the air con. The question is what are the 3 settings on the heater i.e temp/def/ etc. when you turn the knob for the air? I assume that you set to cool then what. I'm sure I need some freon but I want to make sure that I have things set right befor starting on the air con.
thanks
