Programming Conventions
The 700 Series controller is programmed using the buttons on
the keypad. The programming instructions will be described
two ways whenever a section has keypad input.
First, a table shows simplified instructions. Second, text
follows that describes the action. In each table:
"Action" lists the event or action desired.
"Keys" are listed as:
UP for up arrow
DOWN for down arrow
SET for set
REGEN for regeneration
"Duration" describes how long a button is held down:
P/R for press and release
HOLD for press and hold
X sec for a number of seconds to press the button and
hold it down
"Display" calls out the display icons that are visible.
Regeneration Modes
The 700 Series controllers can be regenerated either
automatically or manually. During a regeneration, the total time
remaining of the regeneration will be displayed on the controller.
The current cycle is shown in the lower left of the display.
To Initiate a Manual Regeneration:
• Press REGEN once for delayed regeneration. System will
regenerate at next set regen time (2:00 AM). A flashing
regen (recycle) symbol will be displayed.
• Press and hold REGEN for 5 seconds to initiate
immediate manual regeneration. A solid regen symbol
will be displayed.
• After immediate regeneration has begun, press REGEN
again to initiate a second manual regeneration. A flashing
"x2" symbol indicates the second regeneration will start
at the time of regeneration. Press and hold REGEN to
turn on the second regeneration immediately following
the current regeneration. The double regeneration is
indicated by the "x2" symbol being on steady.
