WL110 Plumbed in...Now on to the Wiring.

This whole time, I didn't realize that the added service switch replaced the switch on the boiler. Now I understand why I didn't understand! So, know on to the remainder of the wiring!

So, had an installer come by today. He told me to buy new zone valves and try to sell my Taco controller. He said my zone valves are a nightmare even with the controller.

Description appears to require a new and different "installer"

maybe one a little more versed in wet system plumbing

- zone valves are a nightmare

How do I connect the power in to this thing? I don't understand this diagram as far as connect the power in to and out to the switch.

Look here at top left diagram:
H and N = L1 and L2 = Black (and sometimes Red) and White

if your having trouble with these clear drawings above
well I recommend you look at these first
or call in an outside contractor

Perhaps I wasn't clear. I need run from the fused switch to the LWCO. I have never worked with a fused switch so I am not certain how to approach the fused switch.

oh
well
UNHEMMMM

Think of it just like a normal switch - and wire as such

its just a "Switch With Benefits"

I've gotten as far as the circulator. Which on goes to C1 and which to C2 on the aquastat?

Don't be overwhelmed...your part is very tiny.

Top right on pg. 15. Your circuit...L1 (black), L2 (white) and ground (green or bare).

Directly to the left of that...Your Fused Switch replaces the factory switch (if yours fits in existing factory box)

Remember: Switch only the black and/or red wires and splice all the white wires in 1 big wire nut.

Let me know when you have that much done.

I finally made it this far!

In your case, the circulator needs wired into Taco panel... not aquastat.

I'm going to upgrade the zone valves, I had a guy come over and he told me mine are a nightmare to figure out. I may try to sell the Taco panel to recoop some of my expense.

I'm not against still using the controller even if I buy new zone valves. I just need to get this thing up and runnning by this weekend. It's suppose to get cold next week.

So, I am going to try putting my old zone valves back on and connecting to the taco controller. I will attach some pics here. So, I assuming that these truly are two wire zone valves with no end switch, there is only the yellow and orange wire. As in the diagram, one wire to 1, one wire to 2, jumper a wire from 3 to 4 due to no end switch. Yellow to 1 or to 2? The diagram seems pretty straight forward. Tips and advice appreciated. The connection to the thermostats is super simple, red to red, white to white. The circulator, just the two wire as shown? Does it matter which wire to which connection? What is the dry contact portion and does it come in to play for my set up? I am starting to get much more comfortable now.

Do this and you're good to go.

Not sure what that installer meant by being difficult. Hardest part for me was using Paint...don't laugh.

Don't worry, I won't laugh at a guy that has stuck with me this far! That makes it even simpler. Just a few more questions. Does it matter which wires (orange and yellow) from the zone valve that I connect in to 1 and 2 on the controller? Secondly to the circulator. Its the hot L1 (to switch) from the transformers to the left side of the pump end switch portion of the controller then from the right side of it to the cirulator. Connect to both circulator wires? I can almost feel it getting toasty in here now!
