Value Description
ADA Sets the control algorithm used to trip the pump
relay to ALTERNATE DUTY ASSIST. Multiple
pumps can run simultaneously.
Sample Value Description
1
1.0 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. For exam-
ple: In cycle 1, pump 1 turns on at 1 m. In the
next cycle, pump 2 will turn on at 1 m.
1.1 m* Sets the level at which pump 2 turns on.
