Specific day of week regeneration (740 only)
To change the controller to regenerate on specific days, set the number of days between
regeneration to zero.
After this has been completed, the arrow on the left side of the display will be pointing
to regeneration time/day. Press the SET 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.
The UP or DOWN buttons are used to turn the days flag on/off. If the cursor is in
position but steady on, use the UP or DOWN buttons.
To move the cursor when it is flashing push the SET button once. This will move the
cursor one position to the right and change the status to steady on.
NOTE : Regeneration on specific day is used to provide regeneration when
water demands are not steady. Example : if the weekdays have low usage and
the weekend is high, then regeneration every three days will not meet the
requirements.
WARNING : 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. See below.
