I wanted to see what the actual temperature probe offset was on my new Bullseye Deluxe so I checked it with a known accurate analog thermometer today. The thermometer was placed through the meat probe hole with the tip situated about 1" from the grill's probe tip. The grill was set at 250 degrees and allowed 20 minutes to achieve steady state. The analog probe read 295 degrees. I opened the Recteq App & went to Settings, then to Advanced Settings, then unlocked it, and then gradually advanced the Temperature Calibration setting eventually ending up at +15%. This resulted in pretty much exact correlation at 300 degrees, 250 degrees, & 225 degrees. There were no flame outs. The ambient temperature was about 78 degrees with a mild breeze. Recteq Ultimate Blend pellets were used.
Hopefully, the attached pics are explanatory. In summary, my Bullseye Deluxe was running 45-50 degrees hotter than the grill probe indicated, 2) it's easiest to change the offset in the App rather than on the grill controls, & in my situation at least, the proper setting was +15 %, & 3) the grill seems to function as usual at usual smoking ranges. Also, the analog thermometer confirms that the grill has a 15-20 degree temp swing on either side of its set point at steady state which is not evident on the grill's display. This was present both before & after resetting the temperature calibration.
