Ⅲ. Function Description
Ⅰ).Initial electrical testing
1.Voltage detection (When A8＝ON, it would ignore the voltage detection)
When it is initially power on, the system is working at a protecting status. LED shows “ ”
The system is testing the voltage from the input transformer, when input voltage is beyond
280VAC, LED shows “ ”, then the system stops working.
If input voltage is below 280VAC, the system will go into normal power supply.
In a normal power supply, turn off all the loads, and test the input voltage again.
It is normal working voltage if the voltage is below 260VAC, It is the over-voltage if it is
beyond 260VAC, then LED shows “ ”. In these two kinds of situation, the system will not go
into normal operation.
Under this circumstance that the input voltage is normal, the system would go through the
following detections in sequence:
2. The current detection of Ozone
3. The current detection of 12VDC Light
4. The current detection of loads’ auto moisturizing. When B3＝OFF, it would ignore the
detection.
5. The current detection of circulating pump
Ⅱ). Temperature Setup (77-104℉/25-40℃)
Being without any settings, the first time to press “ ”or“ ”, it enters to temperature setup. At
this time, the setting temperature is flashing in the LED. Before the temperature stop flashing, press
“ ”or“ ” again, it can change temperature settings. Within 6 seconds without any pressing, it will
exit and save settings temperature, and begin to show the current SPA temperature.
Ⅲ).The Operation of “ ”
1. Press and hold “ ” for more than 5 seconds until it appears a flashing“ ”on the LED,
it means that the system enters to the setting mode, and at the same time, it also enters to a
“real-time clock” setting.

2. Under the setting mode, click on “ ” to set “start time of filter cycle”, the LED shows
“ ”.
3. The 3rd time to click on “ ” to set “continuous working time of filter cycle”, the LED shows
“ ”.
4. The 4th time to click on “ ” to set “tuning temperature”, the LED shows “ ”.
5. The 5th time to click on “ ” back “real-time clock” setting, the LED shows a flashing
“ ”.
When finish setting, (or being without pressing any setting button within 6 seconds) the data
will be saved, and then it exits the setting mode. Any modification must be operated within 6
seconds.
***Note***
1. When A1 = ON or A2=ON, press “ ”, then it skips the 2nd and 3rd steps.
2. Only “ ” has the operation of “press and hold” and “click pressing”, the other buttons are
“click pressing”
3. “Press and hold” means to click the button and hold until it appears some icons or enters to a
certain status.
4. “Click pressing” means to click the button and let go right now, within a second.
Ⅳ). Working Mode
1. When A1= ON, there is without neither work mode or filter function, “ ” is to control the
heater ON/OFF.
2. The switch of the modes (A1=OFF):
2.1 Three kinds of working modes: Normal Mode, Economy Mode and Filter Mode.
The working mode is just effective for circulation pump、heater、circulation filter and antivirus
function.
2.2 When it is power up, the system is working at the “Filter Mode”, and the LED shows “ ”.
The system is just working during the filter cycle, but the heater doesn’t work in this mode.
2.3 The 2nd time to press “ ”, the system enters to “Normal Mode”, and the LED shows
“ ”. The system is keeping setting temperature all day.
2.4 he 3rd time to press “ ”, then the system goes into “Economy Mode”, the LED shows
“ ”. The system is just working during the first filter cycle, and it will heat the SPA to the

setting temperature. And it will not start to heat at the second filter cycle.
2.5 The 4th time to press “ ”, the system enters to “Filter Mode”, the LED shows “ ”.
***Note***
When A2=ON, there is without “Economy Mode” and it will auto ignore the fourth step when
operation.
Ⅴ).Clock setting
At clock setting status, (show as Fig. 4), press “ ” to set the hour (down button), the
adjusting range is from “0 to 23”.And to press the “ ” to set the minute (up button), the
adjusting range is from “0 to 59”
Fig. 3: Current time 12:34 Fig.4: Start time of filtration at 3:00.
Ⅵ).Pre-settings filtering antivirus cycle (Valid of A1=off)
1. It has twice filtering antivirus cycle every day. But it is only able to set the start time for the first
filtering antivirus cycle. And the second filtering cycle is automatically added, it will starts after
12 hours later. (For example, it starts at 14:00 and the start time of the second filtering is at
2:00)
2. When A3 = ON, the time for filtering antivirus is fixed. It starts to work at 14:00 every day, and it
lasts for 3 hours. And the start time of the second filtering is at 2:00.
3. When A3= OFF, at setup status of “start time of filtering cycle” (Fig.4).Press “ ” to change
starting time, and both hour and minute are 00.
4. At setup status of “continuous working time of filtering cycle”, press “ ” to change the
time, the settings are 1-11 hours, and the default time is 3 hours (Fig. 5).

5. At the initial stage of each filtering cycle, all the devices will run for 15 seconds to purify the
pipeline equipment. Ozone starts to work 15 seconds later.
In order to prolong the service life of anti-virus system, every 15 minutes ozone stops working
for 15 minutes.
When any surfing pump (or high speed pump) and blower is power on, the anti-virus system
will stop working at once.
Ⅶ).Temperature Adjust:
Press and hold “ ” to enter to the setting mode, and continuously pressing “ to
enter to Temperature fine-tune mode(Fig.6).At this moment, press “ ” and“ ” can
change the fine tuning number, adjusting range is -7～7℉。
If the current water temperature shows 98℉, but the real water temperature is 100℉.At the
moment, as long as to adjust the fine-tuning number for 2 ℉, the showing temperature will turn
into 100℉.

Ⅳ.The operating instructions of high-voltage load
Ⅰ).The operation of surfing pump
Press “ ” to control the pump ON/OFF, and the surfing pump will automatically turn off
after 15 minutes.
Ⅱ).The operation of the Blower
“ ” is to control the blower for turning on/off. The blower will automatically turn off
after 15 minutes.
Ⅲ）The operation of the Light

There is a short circuit place “light” to see whether the control lamp hold synchronizer inside
or not.
Ⅳ).The operation of “ AUX ”
“ AUX ” is to control an additional load to be ON/OFF .And the additional load can be used
for DVD/TV or others, and its MAX power is 1KW/230V.
Ⅴ) Automatically anti-freeze (It is effective when working with heater)
When the water temperature is below 44℉/6.7℃or much lower, anti-freeze is automatically
starting, all the pumps and blower work for 30 seconds and then turn off. The heater and
circulating pumps turn on. The panel shows “ ”
When the water temperature is reaching 46℉/7.8℃or above, all the heaters and circulating
pumps stop working.
Ⅵ). The operation of auto moisturizing (B3=ON):
1. When the water level pin detects that there is no water, LCD shows “ ”, then moisturizing
function would start auto and at this time, LCD shows “ ”.
2. When it doesn’t reach the water level pin in 30 minutes, (maybe there is no tap water), the
moisturizing solenoid valve would temporary close, then LCD shows “ ”(water flow in
pause), after 30 minutes, the moisturizing solenoid valve would start again. In this way, after it
repeats to fill the water, the “ ” will disappear.
***Additional Remarks***
1. There is a water level detection and a water flow detection inside the heater, which are used for
controlling the heater and the pump.
2. Water level pin is only for auto moisturizing.
