Operating instructions

STARTUP
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 pump can be turned on to
make sure they are fully primed and moving water in the hot 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 - - 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. Press the button to increase or lower the
set points. If the is pressed the set point will flash. Each press will
move the set point 1 degree. If the set point is moving the wrong direction
then stop pressing, let the temperature display stop flashing then press
again to move the set point in the other direction. After adjusting the set
temp the LCD will revert back to current water temp.
Note: if set temp is lowered more than 3°F/1.5C 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
St – Standard Mode (Default Mode): In Standard Mode the
water is always heated to the set temperature. The display will show the
temperature always with Hush Pump equipped systems. If non Hush,
current water temperature will be shown when the pump is running and
– when pump is not running. If your tub is not equipped with a Hush
Pump the 2 speed pump will come on every 30 minutes outside of filter
cycles to poll for current water temperature. If you do not want this to
happen, use the Economy mode below.
Ec – Economy Mode: In Economy Mode the water is heated only
during the filter cycle times. The factory default is F4 - 4 hours, twice a
day. If using the Economy mode, you may need to alter these times to
make sure the water is at your desired temp during your usual tub use
times. The first cycle starts 6 minutes after power is turned on. The display
will show the will alternate between Ec and the current temperature.
SL – 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 SL.
To change heating modes press the button then the button.
MASSAGE
To activate this jet pump press the button once to activate low
speed, twice to activate high speed and three times to turn the pump off.
The low speed will turn off automatically after 4 hours and the high speed
will turn off after 15 minutes. If the hot tub is Hush Pump equipped, the
low speed of the jet pump will come on automatically for 1 minute at the
start of each filter cycle to purge the plumbing lines.
