Air Controls
Display
Pump/Light
Button
Refer to the diagram above. The function of each
control is explained below:
Pump/Light Button: Press the Pump/Light button
once to turn on the light. Press the button a second
time and the low-speed pump and light will run. Press
the button a third time, and the high-speed pump and
light will run. Press the button a fourth time and only
the high-speed pump will run. Press the button a fifth
time to turn off all functions.
The light will automatically turn off after 4 hours of
operation. The low-speed pump turns off after 2 hours
of operation and the high-speed pump turns off after
15 minutes of operation. The low-speed pump starts
automatically when the heater is turned on. If auto-
matically activated, the low-speed pump cannot be
turned off with the Pump/Light button; however, the
high-speed pump may be started.
The controller will automatically filter the spa twice
each day. The first filter cycle will begin 1 minute after
the controller is energized. The second filter cycle will
begin 12 hours after the start of the first cycle. The fil-
ter cycle is set by the dealer for 2 or 3 hours. During
filtration, the low-speed pump and ozone generator (if
installed) run continuously.
Temperature Button: Controls the temperature setting
of the water. The temperature can be set from 80°F to

104°F. The water heats at about 6°F per hour with the
cover on. Use a medical or other accurate thermome-
ter to check the temperature of the water.
Temperature adjustment is controlled by pushing the
temperature button. The display shows the actual
water temperature unless the button is pressed. When
the button is pressed, the display will show the set
temperature. Pressing the button a second time will
cause the set temperature to increase or decrease
depending on what direction was last chosen. Each
successive press will change the set temperature in
the same direction.
If the opposite direction is desired, release the button
and let the display revert to the actual water tempera-
ture again. Press the button to display the set temper-
ature, and again to make the temperature change in
the desired direction.
If the letters OH, FL, or Sn appear in the display, refer
to page 17.
Air Controls: Determine the amount of air flowing
through the spa jets. If a control is turned counter-
clockwise, the amount of air flowing through the jets
will increase; if a control is turned clockwise, the
amount of air will decrease. Test each of the air con-
trols to determine which jets are controlled by which
air control.
