Thermostat with PID controller

Hi guys, I see you are struggling with the PID control for the thermostat. I am the developer of the free pidtuner tool, I can answer any questions you might have regarding PID tuning.

First I would like to point you to this FAQ regarding PID tuning with the tool:

Then I would recommend that you use the canonical arduino PID implementation from Brett Beauregard:

Some PID implementation make some weird additions to the basic algorithm takes helps some people to wrap their heads around manual tuning, but you really don’t need that if you use a tuning tool. Furthermore, most tools assume a standard PID implementation.

You don’t really need to be math experts or have years of experience with PIDs to have a good PID tuning, as long as you use a tool correctly, that’s what tools are for.

Hope this information is useful.
