To unlock the filter cycle programming to make changes, simply press
DISPLAY, MODE and DOWN within five seconds each.
CHOOSING THE “STANDARD” OR “ECONOMY” MODE
Pressing MODE switches your hot tub between the “standard” and “econo-
my” operating modes. The mode currently selected is displayed on the right
side of the LCD screen. By selecting the appropriate operating mode, you can
ensure that your hot tub will be ready to use when you want it with the low-
est possible energy consumption.
Standard/Economy Mode
In these standard/economy modes, the hot tub water temperature will always
be held at the set temperature. The heater will turn on as needed to maintain
the hot tub water temperature you have set with the temperature control.
When the desired temperature has been achieved, the heater will turn off. In
addition, when in the “standard” mode, the filter cycles will operate the low
speed pump as programmed to provide skimming action and additional fil-
tration. In the economy mode: filter cycles are turned off.
PANEL LOCK
To help prevent unauthorized use of your hot tub, the Sentry controls incor-
porate a unique panel locking system which disables the controls on the
panel.
To Lock The Panel:
Press the DISPLAY, MODE, and UP sensor pads, in order, within five sec-
onds. A padlock symbol will appear on the LCD screen.
With the panel locked, none of the components can be turned on and the
only settings that can be adjusted are the standard/economy operating mode
and changing the time of day.
All automatic hot tub functions will operate normally.
To Unlock The Panel:
Press DISPLAY, MODE, and DOWN, in order, within five seconds. The “lock”
symbol will disappear. All sensor pads are now active.
TEMPERATURE SETTING LOCK
To electronically lock the temperature setting, first enter the “temperature set-
ting” mode by pressing UP or DOWN. Then, within five seconds, press the
three sensors described under “Panel Lock” above. This will prevent the tem-
perature setting from being changed by unauthorized persons but all other
sensors will remain active.
