I’ve attached a wiring diagram for the Heavy Duty Switch.
Flood sensors would be used to generate notifications. The goal with the two devices is to monitor whether the water level is rising (flood sensor) or the Sump-Pump power is lost or it is not operating (HDS).
Also attached is an image showing the Sump Pump settings. Once a Heavy Duty Switch is found, you can select the configuration gear on the Sump Pump card and choose the appropriate water sensor to link to it.
