All powered up. Came out great!
Looks great! Can't wait to start working on mine!

Kit cost:180.00
Enclosure:100.00
2 x PID: 91.00
Labels: 30.00
Paint: 12.00ish.
HeatSink: 18.00

This is all approximate but will get you fairly close.

maybe a dumb question, but what are the white 'status' lights for?

They show the status of the PID. If the PID kicks on, you have a light.

Right, sort of. The white LEDs are wired directly to the element 240VAC power, but they ONLY light if the selector switch has selected element through it's respective contactor. Otherwise, though the PID is driving the SSR, the white LED won't come on.

There isn't any indicator showing the PID output (except for on the face of the PID).

Splitting hairs here, sorry.

This is an example of why I am taking years to understand this before I attempt it myself. I am still confused.

I am certainly no electrician, so I apologize for the convoluted question below:

I understand that the yellow light goes on to indicate which element has been selected. Furthermore, I understand that the temp set on the PID will cause that number to be maintained by the element, which may result in some on-then-off-then-on again element power.... All of that being said, does the white light turn on to signify that the element is indeed being used by the PID at the moment? (And thus not illuminated when the temp has been set and the element need not be running?)

Disclaimer: I'm just describing what I see in the schematic, linked above. I don't have this control panel (I built my own several years ago).

The white LED indicates that the element is actually getting power. So, yes to your question. But consider this scenario: you've selected Element #1 with the selector switch; PID #2 is set to 200F. What happens with the LEDs (yellow, white) for Element #2? Do they indicated what PID #2 is doing?

The answer is that PID #2 doesn't have any idea that Element #2 cannot get power. PID #2 will continue to drive SSR #2 in order to turn on Element #2, but Contactor #2 is disabled. Thus, neither the yellow or white LEDs for #2 every come on, even though the PID #2 is happily doing it's job.

You can't really figure any of this out if you don't understand the schematic.
