P1-15 Low Water Input
The iQpump drive can be configured to detect a low water level condition. To activate the low water level detection requires one of the
multi-function digital inputs to be programmed for low water level (H1-xx = 85). The multi-function digital input can be configured to
accept a normally closed or normally open contact by programming the Low Water Input (P1-15).
This function is only active during operation in the Auto Mode.
Important: Refer to H1-xx = 85 on page 158 for further description of the low water level function.
