TEMP CONTROL
The last measured water temperature is constantly
displayed. The water temperature displayed is current only
when the pump has been running for at least 1 minute.
To display the set temperature, press "Warm" or "Cool"
once. To change the set temperature, press a temperature
button again before the display stops flashing. Each press of
"Warm" or "Cool" will adjust the set temperature. After three
seconds, the display will stop flashing and begin to display
the current spa temperature.

low and high speeds. If left running, the pump will turn off
after a preset length of time of 2 hours for low speed and 15
minutes for high speed. Low speed may run automatically at
times, during which it cannot be deactivated from the panel,
but high speed may be operated. The ozone generator (if
installed) will activate anytime low speed is running.
