How to wire circulator/zone valve


I have a Taco 008 Circulator I'm installing. I need the zone valve (standard taco) on the return for this zone to trigger the circulator when heat is called for by the thermostat. The circulator came with only basic wiring instructions, and didn't say anything about a low-voltage input. How should this be done?

Here's the instructions that came w/ the unit:

Terminals 2 & 3 are the end switch on the zone valve. You will need a circulator relay The taco site has all the wiring diagrmas for just about anything you will run in to.

How to wire circulator/zone valve


Thanks!
Here's a link to the wiring diagram for a relay I think would work.

Most of that is pretty self-explanatory, but where do I get the low voltage to trigger the zone valve?

Thanks,
