LCD display. As a lockout feature, the buttons are inactive until the SELECT button is held
down for 5 seconds, and then the display will begin to scroll through the top level of the
configuration menu.

require setting a level for ON and another level for OFF
EMPTY

Typically, Relay ON is the HIGH set point and Relay OFF the LOW set point.

reaches the low set point (OFF) and will remain off until the level returns to
the high set point (ON).
