change set points to configure the controller to operate appropriately for various installation requirements.

Common Tasks Performed Using The OID
Silencing Horn: If a horn is sounding and the alarm is silenceable, a quick
press of the [SILENCE/RESET/ESC] will silence the horn (less than 1
second press).
Resetting Alarms: If the alarm condition has cleared, press and hold the
[SILENCE/RESET/ESC] button 2 to 5 seconds to reset alarms.
Operating Mode Change: The operational mode that the controller is in can
be changed by pressing the [AUTO] [MANUAL] or [OFF] buttons. An LED
will illuminate on the appropriate button indicating the mode of operation the
controller is in.
Test Mode: When controller is in Auto Mode, pressing and holding the
[TEST] button for two or more seconds will open the pressure drain solenoid
thus dropping the pressure, which causes the controller to start the pump.
Pressing and releasing the [TEST] button in Manual Mode directly controls
the opening and closing of the drain solenoid. The pump will not
automatically start when in Manual Mode.
Lamp Test: To illuminate and check all the OID LED’s and the horn, press
and hold the [SILENCE/RESET/ESC] button 5 or more seconds or until all
the lights turn on.
