Value Description
ADB Sets the control algorithm used to trip the pump
relay to ALTERNATE DUTY BACKUP . Only one
pump can run at a time.
Sample
Description
Value
1.3 m Sets the level at which pump 1 turns on. The
first cycle will use this setpoint. Subsequent
cycles rotate the setpoint among the pumps.
1.2 m Sets the level at which pump 2 turns on.
Sample
Description
Value
0.4 m Sets the level at which pump 1 turns off. The
first cycle will use this setpoint. Subsequent
cycles rotate the setpoint among the pumps.
0.3 m Sets the level at which pump 2 turns off.
Value Description
FDA Sets the control algorithm used to trip the pump
relay to FIXED DUTY ASSIST. Multiple pumps
can run simultaneously.
Sample
Description
Value
1.3 m Sets the level at which pump 1 turns on.
1.2 m Sets the level at which pump 2 turns on.
Sample
Description
Value
0.4 m Sets the level at which pump 1 turns off.
0.3 m Sets the level at which pump 2 turns off.
