Re: Sending PWM through a relay
I think you're going to find tuning the control loop will be nontrivial -- there's a lot of lag in your system. You might find each time you "change the (thermal) load -- open the door, add/remove boards -- that the system wildly overshoots (underdamped). Or, takes forever to reconverge at the setpoint (overdamped). As the goal is to maintain a specific temperature, the other issues may prove to be of relative insignificance.
