Waterboy Pressure Switch
The Waterboy Pressure Switch is the perfect way to switch off your pump when your tank is full, no
matter how far away it is.
By use of a double acting float valve installed in the destination tank, the outlet is closed as the tank
fills.
The pump continues to run when this valve is shut, building up pressure in the pipeline. At the
desired pressure the switch opens and the controller stops the pump.
The pump will start up again when the pressure in the pipeline is released as the tank empties.
Always install the pressure switch with the pressure gauge in the upright position.
Wiring
As a standard, BW Solar Pressure Switches operate in the Normally Open (N.O.) configuration for
filling a tank.
In the controller, the terminals COM2 and TH are the N.O. terminals used for the Pressure Switch,
they do not have any polarity.
