Hi All,
Just wanted to say this is a great project and lots of fun. Anyway, I built the heatermeter 4.2 and got a robodamper and started cooking. Everything seems to be working correctly, mechanically and electronically, but when in operation, lets say startup where the temp is set to 250. During ramp up, fan is 100% and robodamper is full open everything looks good. But, when the temp reaches 250, my fan "output" will drive the temp to 290, then temp will drop to 230 and start "ringing." I have a Vision classic b grill with new seals. I tried to adjust the pid but tuning but it requires alot of time a fuel and I would like to conserve both by asking....Anybody using a classic b? What are your pid settings. Anyone else got any suggestions, and again thanks!!
