Note: When using Alternative Wiring diagram, the boiler oper-

ating control’s ZC terminal will see the load of the circulator(s).

Warning: When using Alternative Wiring diagram, wiring

instructions must be followed so power originates from the boiler

aquastat. Failure to follow these wiring instructions may result in

a secondary source of power being connected to the boiler that

may activate it under certain circumstances, causing injury or death.
