P-J Diagram Help
 
Does anybody know of a P-J diagram that has

Two 5500w elements (HLT and BK)
One PID (toggle back and forth to HLT and BK)
Two SSRs
Two contactors
Two pumps

And then the switches, etc.

Anybody?

I've been searching the diagrams and found some that are pretty close, but I don't trust myself to modify a diagram and feel good about it.

How about this?

(BTW: You are only using one circuit at a time so therefore there is no need for a second SSR)

As always, click on the image to see (and save) a full scale diagram printable on Tabloid paper (11"x17")

Hope this helps.

Again, P-J, this is helpful - and the comment about no need for a second SSR. So, if I understand, the only reason for a second SSR would be for having two circuits (say two elements) on at the same time. Is that correct?

That is correct.

So the switch in this one. Would be like an SW2 at Auberins site?

No that is not the correct switch. Use SW3 - Selector Switch, 3-Position Maintained 2 NO. That's the one that is also called out in the diagram foot notes for switch #1.

Hope this helps.
