From my understanding the controller in the 1600 Pro Series uses a different chip set. It looks and operates the same minus the issues of the 1150. That being said, some are having issues with their 1600. My 1600 so far has been great. My only issue is that it does not like to hold 250°. Every other temperature works great.I looked at the 1600 at Lowe's, it looks like it has the same controller as the 1150, we will soon find out if people are having the same problems.
By the way, I haven't seen the 1150 at the 2 Lowe's I go to lately, I wonder if it was removed.
So my 1600 was missing the temperature knob. Not a big deal. PitBoss said they don't have just the knob, but would send a whole new controller. Seems wasteful for a 50 cent knob, but ok. Waited 2-3 months for the new controller hoping it would be firmware upgraded with the smaller temperature increments I'm desperate to have. Removed the bottom panel and had three screws that were frozen in place. PITA and the screws are trashed. Not the end of the world. Put the new controller in to find out that it does NOT have any different temperature increments than the old one. Now I have to find replacement screws. Would have been better off ordering a generic knob on Ebay and saving myself the friggin' hassle. Otherwise I like the grill, but the temp/app issues are really aggravating.Who has the 1600 pro series? I would like to know if this has the same controller in it as the 1150. Are you still experiencing the same temp problems from 200 - 300.
