PUSH BUTTONS
The regulator has 4 buttons: ON / OFF, MODE, UP and DOWN.
Note: If the backlight is off, the first press turns on the backlight. With the backlight on, the push button functions are as described below.
Basic functions:
• ON OFF:
Short / long press: Select the on / off state of the regulator.
• MODE:
Short press: Selects the auto / manual regulation mode.
Long press: Access parameter mode.
Parameter configuration: With MODE the parameter to be displayed is selected, and with UP and DOWN its value is modified. With ON / OFF the parameter settings are sold, returning to the normal operating mode. See annex for configurable parameters of the REG FILTER regulator.
• UP:
Short / long press: Automatic mode: Increases the pressure setpoint (0Pa-10000Pa).
Manual mode: Increase the speed setpoint (0% -100%).
• DOWN:
Short / long press: Auto mode: Decreases the pressure setpoint (10000Pa-0Pa).
Manual mode: Decreases the speed setpoint (100% -0%).
Note: If MODE + UP is pressed continuously when powering the regulator, or after a reset, it returns to the values by defect (showing dEFEC on the screen).
