10.0 Programming Instructions
10.1 Adjusting Time of Day
The Sentry control system remembers the time of day even in the event of a
prolonged power outage. However, it may occasionally be necessary to reset
the time of day. For example: if you are not in the Pacific Time Zone you
will want to reset the time for your own time zone. (The system will auto-
matically adjust to and from daylight savings time.) To accomplish this,
press DISPLAY, MODE and DISPLAY within five seconds each. A number
representing the hour will be displayed, followed by AM or PM. The hour
will advance or decrease each time UP or DOWN is pressed within five
seconds. Then, press DISPLAY again to display the minutes. Adjust the
minutes as necessary by pressing UP or DOWN. After 5 seconds, the dis-
play will return to normal.
10.2 Changing The Skimming/Heating Cycle
The Sentry Control System allows you to easily adjust two separate aspects
of the skimming/heating cycle (1) the time of day at which the cycle
begins, (2) the duration of the cycle. To make adjustments, first press
CYCLE to enter the skimming/heating cycle programming mode. The LCD
screen will display the following in the upper right corner:
ADJUST START TIME
FILTER
CYCLE
This means the system is ready to accept your changes to the start time for
the skimming/heating cycle. Simultaneously, the large four-digit display in
the center of the screen displays the currently programmed start time for
the cycle. At this point, you have four options. You may:
(1) Press UP or DOWN to adjust the start time in increments of 30 minutes.
(2) Press SELECT to move down the menu from Start Time to Duration.
Press UP or DOWN to adjust the duration in increments of 15 minutes.
(3) Press DISPLAY to make the skimming/heating cycle programming
characters disappear from the screen and the main display return to
showing water temperature. If no sensor is pressed within 30 seconds,
the screen automatically returns to the standard water temperature
display.
