OK, I probably should have thrown in some more specifics when I ask you that question JP. Below is what I am looking to do. If anything seems off, someone please chime in.

2 gas valves- one for the HLT and one that is just on/off for the BK.
2 pumps- I want to use one of these to incorporate a HERMS coil in my HLT. I think that's how it's done, right? The other will go from MLT to BK.
I would like to be able to have an intermittent pilot, but I guess that isn't a huge priority.

I want to bump this one again to see if anyone has a diagram for a single tier 3 kettle system with single pump. Here is what I am wanting to use.

MLT & HLT using PIDs with RTDs controlling Honeywell Y8610 electronic ignition gas valves.
BK on a switch controlling Honeywell Y8610 electronic ignition gas valve
and a temperature display with an RTD.
The pump is on a switch.

Your request for an intermitent pilot is really dependent on the gas valve you choose to employ in your build. The one I chose to illustrate in the diagrams has a standing pilot. Burner control is implemented through the SYL-2342 PIDs.

Here is a diagram with the second pump added:

As always, click on the image to see (and save) a full scale diagram printable on Tabloid papr (11" x 17")



Hope this helps.

Thanks PJ. So where the little dots in the lines are, you said previously that the line went back to the same spot in the terminal. Does that mean each terminal will have multiple wires contacting it, or splice the intersecting wires together?

It is however you choose to set up your wiring.
Use a larger terminal strip with jumper strips.
Splice the wires as you choose.
Strip a small piece of insulation from a wire run & fold it back in itself - then crimp on a terminal.

It is all yours to decide. I illustrate it the way I do it so that the drawing remains fairly simple and easy to follow.

PJ, thank you so much for clarifying this for me. My PIDS are on order as well as my RTD's from AUBER . I found an old post of yours discussing the merits of cheaper EBAY RTD's vs Auber's RTD's.

Again, you are a valuable resource for those of us who are somewhat clueless when piecing together these electrical systems.
