Tech Tips

• If a 120 VAC bell is going to be connected to a flowswitch, the wiring method will be similar to wiring a light switch to turn on a light bulb. The flowswitch is just a switch. Use it to switch the hot wire to the hot side of the bell. The neutral wire should not be connected to the flowswitch. It should go directly from the service panel to the neutral of the bell.
