LCD Display Navigation
This section describes how the keypad is used to navigate the
LCD display and menus.
The LCD displays up to three lines of text at a time. For menus
with more than three lines, use the up and down buttons (
v) to scroll through the menu options. As the menu is scrolled
up or down, the indicator arrow (←) shows which menu item is
active.
1. If the active menu item is part of a list of predefined
options (e.g., AUX.PUMP operation), press the OK but-
ton to edit this value (the word EDIT displays on the top
right portion of the AQ254 LCD screen) and then press
either the "-"or "+" button to scroll through the available
options. With the indicator arrow (←) beside the chosen
option, press the OK button again to accept this value,
exit EDIT mode, and return to the previous menu. The
option's value is automatically saved upon exiting EDIT
mode.
2. If the active menu item requires you to define a value
(e.g. a setpoint), position the indicator arrow beside the
menu item and press the OK button to edit this value (the
word EDIT displays on the top right portion of the AQ254
LCD screen) and then press either the "-"or "+" button to
change the value for the menu item until the desired
value is shown. Press the OK button again to accept this
value and return to the previous menu. Again, the
option's value is automatically saved upon exiting EDIT
mode.
3. If the active menu item leads to a further sub-menu,
pressing the OK displays that sub-menu. Scroll through
this sub-menu to position the indicator arrow (←) beside
the menu item to be reviewed or modified. Press the OK
button to edit this value (the word "EDIT" displays on the
top right portion of the AQ254 LCD screen). Choose one
of the options provided or input the desired value for the
menu item. Press the OK button again and your selec-
tion is saved.
4. To define or modify another item within the same menu,
scroll the UP and DOWN buttons (
tor arrow (←) is beside the desired option and repeat
Steps 1 through 3.
To move back (up) one level within a menu, scroll to the bottom
of the current menu list and – with the active indicator arrow
(←) beside the EXIT option, press the OK button.
To leave INSTALLER MODE and return to the Home Page
display screen, press and hold the OK button for 3 seconds
