Quote:Nope. Not correct in the case of "basic" controllers. Their controllers don't know anything about temperature. Advance the knob, the power stays on longer, etc. For temperature control where no current is applied until you need it, you want a DewBuster or one of the temperature regulated Kendricks.
Quote:U want to turn the controller on early. U want to prevent dew not go into emergency dew removal.

Quote:If you KNOW you get dewed out starting at one, just set your watch or phone alarm to go off at 12:30, and pop your dew straps on. Easy peasy.I just built a dew controller and set of straps using 12v PWM controllers from Amazon ($7.50 each shipped via Amazon Prime) but am now pondering a few PIDs...
Quote:Quote:U want to turn the controller on early. U want to prevent dew not go into emergency dew removal. If I typically get dewed out at 1am, it seems like a waste of batteries to run it much earlier then that. I'm guessing that's what the regulated ones do, only turn it on when reaching the dew point.
Quote:Thanks Rod. I hope to see and buy my first at NEAF.
My big concern is that I'd rather not have a seperate battery for the heaters. I have a 28ah battery that runs my mount, laptop and camera. I may be asking too much.
