Getting closer and closer to actually building this thing. Most of the components are sitting in a big pile. Pulled some new wiring in the garage and added another 240v outlet. Sold my hottub and ended up with a spa panel that had no purpose. . .handy!
So, my question is. . . I plan to build this in stages. For now I just want to run with the PWM and add a PID later. I like the simplicity of manual control with PWM but I like being able to set temps with the PID.
So, for stage 1, I'd like to have a switch set up for either full power to the element or run through the PWM (as I understand the PWM doesn't do 100% duty cycle)
I'm using bits and pieces of PJs wiring diagram below. There will be no PID for now so whats the easiest way to have a 100% power and PWM switch?
I'm a fairly competent electrical guy but I just want some opinion before I push on.
(I know all this is overkill for a single vessel eBIAB set-up, but I just like tinkering. . .)
