I want to check the wiring on a Taco Zone Relay 404. The wiring diagrams I have show different products, some show six zones some show only one end switch. The boiler is using a HW L81481 aquastat and has an indirect water heater. The relay I am looking at has two end switches and one set of N.O. N.C. dry contacts.
What should the circuit be for the indirect circulator?
