Okay - well that's a shame... Thanks Sarge for looking into it for me. I am using a Digi-Q right now to monitor the butt and smoker temp (clipped to rack that the butt is sitting on) but of course does not control smoker temp. The meter serves double duty on my Primo ceramic, controlling temp via a fan. I'm having issues with the analog controller on the model 2 - setting and actual are way off, having difficulty maintaining a desirable steady temp. Understand it will drift as the cal-rod turns on and off but this seems drastic. I guess I will look into the digital controller - so does the smoker plug into the controller and that is how it monitors and controls? Thanks for the replies and Happy Memorial Day.
