Operating instructions

START UP
Before turning on the power make sure you have read the
Start Up instructions on page 6. When your hot tub power is
first turned on it will display a series of numbers identifying the
software version and the voltage input. It will then go into a 4
minute priming mode indicated by a Pr on the LCD display.
During priming mode the Hush Pump™ will circulate the water
through the filter and heating system to allow the temperature to
be read. If your tub is not Hush Pump™ equipped the jet pump
will not turn on until the prime mode times out or the
button is pressed to time out early. During prime mode the jet
pumps can be turned on to make sure they are fully primed and
moving water in the tub. Do not allow an unprimed jet pump
to run for more than 10 seconds. If the fill water temperature
is below 44°F/ 7°C freeze protection will activate all pumps
immediately. While the circulation pump is running the display
will show a - - °F indicating current temperature is not known.
This will take two minutes. Once temperature is known it will be
displayed on the LCD.
TEMPERATURE ADJUSTMENT
The temperature range is 80°F - 104°F / 26.0°C – 40.0°C.
The default is 100°F/37.5°C. Any temp changes are saved in
the system memory if power is interrupted. Use the button
to increase and the button to lower the set points. After
showing set temp the LCD will revert back to current water temp.
Note: if set temp is lowered more than 3°F/1.5°C below current
water temp the Hush Pump™ will stop. The circulation will
restart every 30 minutes to check if water temp has come down
to set temp. It will also run continually during programmed times.
HEATING MODES
Std – Standard Mode : (Default mode) In Standard Mode the
water is always heated to the set temperature. The display will
show the current temperature and the word STANDARD.
Ecn – Economy Mode : In Economy Mode the water is heated
only during the filter cycle times. Default times are 8:00 am to
10:00 am for cycle 1 and 8:00 pm to 10:00 pm for cycle 2. If
using economy you may need to alter these times to make sure
the water is at your desired temp during your usual tub use
times. The display will alternate between Ecn and the current
temperature and display the word ECONOMY.
SLP – Sleep Mode : In Sleep Mode the water is only heated
to within 20°F/11°C of your set point and the heater only comes
on during the programmed filter cycle times. This mode is
typically only used for vacation time. The display will alternate
between the current temperature and SLP.
To change heating modes press the button then the
