10. Day Override (Display Code DO)
Press the Extra Cycle button . Use this display to set the Day
Override . This setting specifies the maximum number of days
between regeneration cycles . If the system is set to a timer-type
control, the day override setting determines how often the system
will regenerate . A metered system will regenerate regardless of
usage if the days since last regeneration cycle equal the day override
setting . Setting the day override value to "OFF" disables this function .
This option setting is identified by "DO" in the upper left hand corner
of the screen . Use the Up and Down buttons to adjust the value as
needed . Specifically, Filox filters need to be set to a DO of 1 .
