Float Switch (FS) Backup
About Float Switch Backup
This digital feature is used with a float switch, where it can be used alongside
a transducer or as a backup method for when a transducer goes into failsafe.
The high input will have a timer and a level set point, which will allow for the
unit to power on every pump below the set point for the specified amount
of time as set in
P332 Pump Run Time .
The low input will simply switch off all the pumps that have been set on the
controller.
