Not exactly.
The Intellitech control IS the relay. The wall switches are momentary. When the Intellitec control "sees" that momentary ground signal it closes the latch relay inside the controller and then the ground is completed to the water pump. The water pump already has 12 volt positive all the time. So, once this happens the pump has ground and positive until you turn the Intellitec OFF. The pump will operate once the inside pressure drops and the pump pressure switch closes. Once the water spigots are OFF and the pressure switch is satisfied, the pump will turn OFF until you open another faucet. Doug
