Pressure Mode Operation
In the pressure mode of operation the PSI LED will be on. The PumpBoss will
maintain a constant discharge pressure within system capabilities. It will adjust the
engine RPM automatically to compensate for variations in pressure.
Note: When changing from RPM mode to pressure mode the pressure setting
will be the pressure that the pump was operating at in RPM mode.
1. Press and hold PSI mode button for 3 seconds.
Result: PSI LED goes on.
2. Press PRESET and/or rotate control knob to select pressure setting.
Result: Message display shows PSI setting, engine RPM changes.
3. Press IDLE button after operations to bring engine to idle RPM.
Result: Message display shows date and time, engine at idle RPM.
Opening/Closing Discharge Valves
In pressure mode the PumpBoss will maintain the pressure setting regardless of
the number of discharge lines that are opened or closed providing there is a sufficient
water supply. As lines are opened the discharge pressure will start to drop and the
PumpBoss will raise the engine RPM to maintain the required pressure. As lines are
closed the discharge pressure will start to rise and the PumpBoss will lower the engine
RPM to maintain the required pressure.
