■ Overview
This parameter will allow the drive to control pressure when there is adequate water inside of the well. When the well level drops to the
Water Level Setpoint (P8-03), it will regulate the well level and the pressure will be allowed to drop. The drive will also go to sleep, wake
up, and / or alarm / fault based on well water level.
