Servo versus fan overlap... pseudocode?
Hey folks, Heatermeter seems like such a great product and unites BBQ with my other passion of 3d printing.
I have been wondering, and have searched but not yet found a description of how the servo and fan are used together to control temps. Don't have one yet to try so I'll just ask:
How does the controller use the servo and fan together, or does it? Obviously the wider the vent the higher the airflow so one method would be to only use the fan for startup (with vent completely open) then switch off the fan and use the vent only to moderate air flow. Now I guess depending on fan capacity, draft and some other things there could be a dead spot where one would need to partially close the vent and partially run the fan. There seem to be an infinite combination of fan/vent settings for the same airflow.
What is the heater meter approach to this? Would love to get a brief "pseudocode" description of the algorithm to better understand. Of course I can look at the code and have, but found it a bit daunting at first glance, maybe understanding how it works first would speed understanding of the code.
Thanks!
PS have a Primo Large and love it. Just added a Smokeware vent and thinking of getting Heatermeter for low and slow. Might be fun to mod the system to use a blower but control the top vent instead a la Smobot.
