keyword=Replaced Oven Temperature ControllerI replaced the oven temperature controller for the previous one had some weird behavior ( different response before and after hard reboot). The new one was actually manufactured before the old one and will lose communication occasionally, as seen in the strip chart. But that won't hurt us in real oven temperature and polarization. I only simply set some initial PID parameters, and will do more tunning after lunch.
