I’m using an ITC-106VH with an SSR for an egg incubator. I’ve been using an Inkbird temp controller (just on/off control) with good luck. But want to dial it in a little better. With on/off control my incubator swings +2/-3 degF. Not terrible.
So, being an electrical engineer and a tinkerer. I thought, why not buy a PID controller and really dial this thing in. Well… it isn’t working. With default settings (or any settings, honestly) the PID controller swings +3/-4 or possibly even worse. I tweak integral by setting I to 9999 and D by setting to 0. I would love to be able to just run proportional control such that it feathers up just under my 99.5 degF setpoint, but I simply can’t. Try as I might, the thing just does the same regardless of what parameters I use. I’ve done several autotunes and the results are the same. This thing functions basically like an on/off controller. And to be honest, WORSE than my other Inkbird controllers without PID ability.
Is mine broken?
Thanks!
