I could manage it manually too but it seems fairly easy to modify a standard relay driven electronic thermostat to open and close the circuit. I could do it manually, takes a little bit of diligence but in reality I'm trying to maintain a 10 degree temp swing and if it drops low I don't mind. Makes it easy for me to control. I'd imagine that when it is 20 degrees outside during the hottest part of a MN January day, I won't have much worry about the house overheating. I could always use something like this to cycle outside air directly through the solar air heater to bring in outside fresh air. I'll leave it at that before things the topic gets too far off track with the solar air stuff to respect the OP's thread.
