WARNING: 742 only - Setting days between regeneration to zero will cause
the system to not regenerate. This setting is used for selecting regeneration
on specific days or to use with a remote regeneration input.

Step 6a: Specific day of week regeneration (742 only)

button and the display will show a flashing cursor at the top under
Sunday. The day of week can be selected when the cursor is
below it.
• To toggle the day on/off, the triangular cursor must be below that
day and flashing.

This will move the cursor one position to the right and change the
status to steady on.
