Today installed an Auber SYL-1615SYS-G Temperature controller on my Char-Griller Acorn . Nothing to really do but set blower in bottom draft control channel and attach wires and temp probe . When I first got it going Fire went out in about 30 minutes . MY FAULT! I initially had top draft opened too much ,over shot temp and then shut it down WAAAY too much . Put out fire !!! Restarted it again found the sweet spot for top vent opening and (knock on wood) it works like a dream . Fire size was small ,about 1/4 of what would be normal. Set it for 232 ,and watched it maintain temp of 233-227 . Never have I been able to cook with charcoal with such ease . Between the Acorn and the Auber this is one kick A#% setup . To say I am happy with my purchase would be an understatement .
