If you select Off, the relay will not activate again until either Hand or Auto is selected (or if power
is cycled)! If you select Hand, the relay will activate until either Auto or Off is selected, or until
the Hand Time Limit (programmed in the next menu) expires or until the controller power is
cycled.
The Off mode is handy to prevent the relay from activating while you are changing set points. The
Hand mode is handy to be able to test the pump or valve, wiring, etc without needing to change set
points.

6.35 Relay (1 - 8) Output Menus – Target PPM Feed Type
This page is used to set the flow volume to trigger feed, PPM set point, etc. Which units of
measure appear depends upon how the flow meter input assigned to the relay is configured. If you
make changes to the Input Assignment, you will need to click on the “Submit” button in order to
see all the correct units.
You may also change the Relay Control Mode here. If you do, you will have to reselect the Input
Assignment as well.
This section assumes that the Relay Control Mode is set to Target PPM Feed. Other control mode
types are described in other sections of the manual.
