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 HushPump™ will

circulate the water through the ﬁlter and heating system to allow the

temperature to be read. If your tub is not HushPump™ 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

tub. Do not allow an unprimed jet pump to run for more than 10 seconds.

If the Fill water temperature is below 50°F/ 9.5C 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 HushPump™ 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 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 HushPump™ 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

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.

: 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.
