Did I screw this up?
Not a pro, but this forum always helps me get through it.
Had a sticking relay on my hot water system (fun to wake up in a 85 degree bedroom), so I went and got a resideo one, I thought the wiring was pretty straightforward but maybe not.
When I call for heat, the x1 and x2 fires my boiler, but my circulator pump doesn't start and the relay light stays dark.
Incoming power has the Hot on L1 and Neutral on L2.
Pump load shares the neutral via wago wannabe and the black is on N.O. (3).
What am I missing?
Many thanks in advance.

What is on the "common" on the other side of the relay……………might call it #4?

Nothing on common.
I'm now seeing the dot on the wiring diagram, I thought that L1 was jumpered to common already but looks like they want me to do it, wiring it up now.
That's probably the problem?

That's your problem.
Bring L1 over to the "common".

A new record in my idiocy, thanks for the reply!

Nah……….we all forget things every so often…………..don't fret it.
I recently installed a ceiling light fixture and could not understand why the decorative ornament would not properly fit over the glass shade. Was going to ask the manufacturer why it would not reach the ceiling mount.
Took it back down and found I had put A SECOND GLASS SHADE from a different light fixture beneath the proper one. That's idiocy!

If you have one zone of heat, I'd run the circulator continuously. I have my circulator set this way with an outside sensor to kill the pump above 65 degrees. I'm a fan of super simple where possible.

I really hope you have an ECM circulator. With a PSC circulator, you spend a fortune. I recently added a timer to the recirc (PSC) to cut the circulator time in half. At $0.33 per KWH, it really adds up.

we pay .15 per kwh, the energy drawn from the boiler in standby along with the quick response to a call for heat and the increased longevity of the cast iron boiler is most likely a wash, although I've never measured the added cost of electricity. One benefit not personally realized as of yet, if the boiler was to stop heating the system would not freeze under constant circulation. I know this to be a fact as I'm not only an hvac contractor but a landlord. I had house vacant for 5 years, the heating system was filled the potable system was not. On the rare occasion when I felt like renovating the place in the winter it was easy to get it up to temperature by turning on the gas. It was a 5 year renovation because I did all work without obtaining permits, and out of pocket because no lender was interested in the then risky area the house was located. I was given the house for free, by the owner. It was worth a negative $500 at the time.

A common ECM circ Alpha 15-58, Taco 007ECM run about 37W at full speed. In a heating climate figure about 5000 hours X .15, or whatever you delivered Kwh costs are.
In some cases that continuous circulation can move some solar gain throughout the building. My shop overhear door with partial glass faces south. On a sunny day the front portion of the slab is warmed and circulated throughout.
So the cost of operation may overcome some fuel savings and the comfort benefit.

In your situation this is invaluable. The cost is irrelevant considering the mitigation of risk.
