Help Wiring a Relay, Aquastat and Circ for a Steam Boiler Baseboard Zone

tcassano87

I have to reconnect a Basement baseboard zone to a new installed steam boiler. There will be a thermostat to control the basement. Looking for some help or a diagram on best way to wire the relay, circulator and aquastat together and to the boiler so it shuts down the circulator when temp his 180. Not sure if the photo I sent would worked I’m seeing the Aquastat should get its own power and then wire the circulator separately. C1 & C2 would feed the circulator obviously

Its a Burnham IN6 for reference

Using a Honeywell L4600A2007 Aquastat

Taco 007 Circulator

And either a

Taco SR-501 or a Honeywell R8845

HVACNUT

That works.

Thanks for your help c so the aquastat doesn’t need to get directly fed with line voltage power, it can come off the thermostat wiring
