auto fill wiring

Can anyone tell me how to wire a wf2-u-24 auto fill to a model 47 LWCO. The boiler circut is 24 volt and the LWCO has three terminals on it, common, open and closed.

The feeder wires to common on transformer and NO on the LWCO. When the float drops the NO contacts become closed and the water feeder will feed as the circuit is now completed. Remember to monitor the water level manually as auto feeders on steam boilers are for emergency use only.
