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.
