P111	3	56
Set the Relay ON Setpoints [MR 200]
Parameter	Index		Value	Description
P112	1		0.4m	Sets the three setpoints for the pump relays.
P112	2		0.3m	The first cycle will use these setpoints.
P112	3		0.2m	Subsequent cycles rotate the setpoints
				among the pumps.
Set the Relay OFF Setpoints [MR 200]
Parameter	Index		Value	Description

				with caution.

Optional Pump Controls

Starting Pumps by Rate of Level Change [MR 200]

Use this function when multiple pumps will be controlled by rate of level change rather than setpoints. Pumping costs can be reduced because only the highest ON setpoint needs to be programmed. This results in a lower difference in head to the next wet well which, in turn, results in less energy being used to pump out the well.
