+1 on the switch. For the sake of portability, I was thinking of setting it up in a box where I plug in the element into a regular 120v house plug on the outside of the box. I was thinking an on/off switch on this plug, so I can have manual on/off on the element without having to turn off the PID. (This would be an on/off switch between the SSR and element.)
Is that what you are talking about?
Or would I need to put something between the PID and SSR?
Are there pros/cons either way?
