OK button: selects a highlighted menu item (also toggles between lower and uppercase letters and pressure units). Press and hold for at least 3 seconds to turn the Control Unit off. (However, this will not work in the Contrast Menu, you can only use the left cursor key to exit the menu, and the plus/minus keys to adjust the contrast.)
Cursor keys: navigate through the menus and menu items.
The Control Unit will turn off automatically after 5 minutes of being idle, provided that cycling is not active.
Plus/Minus keys: cycle through numbers and letters when editing or creating new flow rates. Increase/decrease LCD display contrast. (Hold down to scroll quickly through values).
Manual Control Valve: allows manual operation of the Control Unit. When pushed the solenoid opens.
