If ALL of the days were set to "no", then specific day of week regens will be canceled and will
appear as shown in Regeneration Interval above, and the interval will be set in number of days.
Pressing the "STATUS" key saves the setting and advances to the next programming step.
Note: If any day of the week is set to "yes", the regeneration interval in number of days
("Days 03") will no longer appear when going through the programming menu at a later
time. To go back from specific day of week regeneration to interval in number of days,
choose "NO" at "dAYoWK".
8. Programming Mode Timeout - If no key activity occurs for a period of 180 seconds (3
minutes) while in programming mode, the mode will time out, exit the programming mode and
return to time of day display. Any setting that wasn't saved by pressing the 'status' key prior to
the control timing out will revert back to the original value.
