12v topoff controllers use a 12v pump or solenoid valve (listed below). If you want to use a 120v pump, you will need a standard or longwire controller.

12v controllers feature a low voltage float switch circuit with removable float switches that have longer wires than our standard controllers. Can be used to control devices up to 5A but only a 1A power supply is included.

You need float switches with a JST connector to mate to the controller (listed below). If you'd like to connect your own float switches email us and we can put different float switch connectors on your controller
