backwash (the blue Hourglass Icon will be lit) and the Backwash Start Time (only the green key
is lit).
Sample Displays Showing Service Mode and Backwash and Fast (or Rapid) Rinse Modes:
Four Service Buttons: Left to right, Menu/Confirm, Manual/ Return, Scroll Down, Scroll Up.
Up and Down Arrows: When the Green Key Icon is lit, press and hold both buttons to unlock.
When the Dynamic Display Stipe is blinking, pushing the up/down buttons has no effect.
When the Green Wrench icon is lit, pressing either up/down arrow will scroll through the menu
options. There are a total of seven Menu items (explained later).
Menu/ Confirm Button (the button on the far left, an empty square with an arrow pointing
left): This is the button you press (after you have unlocked the screen) that puts you in the
Service Menu, so you can program the valve. The first time you press it, the Dynamic Display
Stripe goes away and the Green Wrench icon appears. Whichever of the Icons is lit at this time,
pressing the Menu/ Confirm button again will now cause that Icon’s value to flash, on the red
digital display.
Manual/ Return Button: Second from left, button icon is a “pointing index finger” with a left-
pointing arrow underneath.
Pressing this button in Service Mode (Dynamic Display Stripe is running) will IMMEDIATELY
start a backwash cycle. Pressing this button when in Program Mode will return you to the
Service Mode.
A. Time of day indicator
• When the blue Clock Icon is lit, the digital display is showing the current time. That time is
displayed in 24-hour format, i.e. 13:00 is 1:00 pm.
