The wiring diagram for its use is according to which boiler you have. There is no universal diagram for every boiler application that can exist.
Generally, the hot wire goes to R, so both burner or circulator can run, W goes to the water circulator, B goes to burner. Each of those burner and circulator circuits has its white wire that doesn't go to the 11A61, but to all the white wire neutral grounds.
