11.0 Programming Instructions
11.1 Programming Filter/Circulation Pump Run Time
The Sentry control system allows you to easily adjust two separate aspects of
filter/circulation pump operation:
1. The time of day (start time) the filter/circulation pump turns on.
2. The length of time (duration) the filter/circulation pump operates.
The factory default start time is 12:00AM (Midnight). The default duration is 24
hours. To make adjustments, press the CYCLE
button to enter the filter/
circulation pump programming mode. “Circ” appears on the LCD. Now, the
system is ready to accept your changes:
• Press the SELECT button once. The previously programmed
start time appears on the LCD display.
• Press WARMER or COOLER buttons to adjust the start
time in 30-minute increments.
• Press the SELECT buttons to program duration.
• Press WARMER or COOLER buttons to program the
duration time in 1 hour increments.
• Press DISPLAY button to save changes and recall the main water
temperature display. Note: If no button is pressed within 30 seconds, all
changes are recorded and the screen automatically returns to the standard
water temperature display.
Note: When the standard mode is selected (sec. 10.3, page 34 ), the filter/circu-
lation pump automatically turns on for a heat call regardless of the pump’s
programmed start time and duration.
11.2 Programming Filter Cycles
Your spa comes with four 30-minute filter cycles which activate the filter/circu-
lation pump. These cycles are factory programmed to start at 6:00 am, 12:00
p.m., 6:00 p.m., and 12:00 a.m. The control system allows you to easily adjust
two separate aspects of each cycle: 1) the time of day at which it begins; 2) the
duration of the cycle.
Note: When “Standard” mode is selected (sec. 10.3, page 34 ) and the filter/circu-
lation pump is set to the factory default duration of 24 hours (sec. 11.1), no
apparent change of operation will occur. However, when “Economy” mode is
selected (sec. 10.3, page
34 ), the heater activates only during a programmed filter
cycle.
