12.0 Programming Instructions
12.1 Programming Filter/Circulation Pump (Standard Mode)
The Sentry control system allows you to easily adjust two separate
aspects of lter/circulation pump operation:
• The time of day (start time) the lter/circulation pump turns on.
• The length of time (duration) the lter/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
once to enter the lter/circulation pump programming mode. The LCD
screen will display “Circ” At this time the system is ready to accept your
changes:
• Press the (SELECT) button once. The previously programmed
start time appears on the LCD display.
• Press (UP) or (DOWN) buttons to adjust the start time in
30-minute increments.
• Press the (SELECT) buttons to program duration.
• Press (UP) or (DOWN) 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 (Section 11.3), the lter/
circulation pump automatically turns on for a heat call regardless of the
pump’s programmed start time and duration.
12.2 Programmable Heat Cycles (Economy Mode Only)
Your hot tub comes with four 30-minute lter cycles which activate the
lter/circulation pump while in economy mode. These cycles are factory
programmed to start at 6:00 AM, 12:00 (noon), 6:00 PM, and 12:00
(midnight). The control system allows you to easily adjust two separate
aspects of each cycle:
• The time of day at which it begins;
• The duration of the cycle.
Note: When “Economy” mode is selected (Section 11.3), the heater
activates only during a programmed lter cycle period. When a Summer
Logic condition is active (page 39), the lter/circulation pump will turn on
for all programmed lter cycles.
