10.2 Changing Skimming/Heating Cycles
The Sentry Control System allows you to easily adjust two separate aspects
of each of the skimming/heating cycles (1) the time of day at which each
cycle begins, (2) the duration of each cycle.
To make adjustments, first press

programming mode. The LCD screen will display the following in the upper
right corner:

This means the system is ready to accept your changes to the start time for
skimming/heating cycle number one. Simultaneously, the large four-digit
display in the center of the screen displays the currently programmed start
time for that cycle. At this point, you have four options. You may:
(1) Press
UP
or
DOWN
to adjust the start time in increments of 30 min-
utes.
(2) Press
CYCLE
to display and adjust each subsequent skimming/heating
cycle start time. With each press, the currently programmed status will be
shown in the large four digit display. To adjust any displayed value, simply
press
UP
or
DOWN .
(3) Press
SELECT
to move down the menu from Start Time to Duration,
with each press, the currently programmed duration will be shown in the
large four-digit display. Press

or
DOWN
to adjust the duration in incre-
ments of 15 minutes.

to make the skimming/heating cycle programming
characters disappear from the screen and the main display return to show-
ing the water temperature. If no sensor is pressed within 30 seconds, the
