I would never laugh bro, I ain't like that. One time 16 yrs ago I rented a house from my racing partner and I could not get the heat to come on after moving in & after moving the horizontle slide on top over to ~80 deg F (where I like it) & no heat so I called him & he called the utility company & they took care of it (I wasn't home when the tech showed up) but I got a call shortly thereafter from John chiding me severely cuz evidently you have to switch the other nub on the side from off to heat in addition to the temp. Cost him a trip charge. I caught hell for that (I'm his ace mechanic) for a week. Good to hear you're squared away (& got an edumacation). Keep your promise now
