Output Mode
Click on the radio buttons to manually control the relay. The normal selection will be Auto, where
the controller uses the various set points to open and close the relay. You can force the relay closed
regardless of the set points by selecting Hand, or force the relay open regardless of the set points
by selecting Off.
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.
Click on the “Submit” button to save the changes.
