function is optional). The panel now shows a DVD symbol at the same time (Under DVD status, press the +/- key to
adjust the volume of the DVD). Press for the fourth time to show the detected water temperature.
TUN/VOL key (needs to be used together with the +/- key): Under Radio status, first press the TUN/VOL key. The
panel will now show a 2-digit volume, pressing +/- will adjust the volume upwards or downwards (the panel will
automatically show the radio frequency when you stop adjusting for 3 seconds). With a second press,the current
frequency will flash. Pressing the +/- key will adjust the current frequency. This frequency will be stored
automatically after flashing for 3 seconds. With a third press, the panel will show the radio channel. Press the +/- key
to select pre-stored radio stations ( the panel will automatically show the previous radio frequency after you stop
adjusting for 3 seconds). With a long press for 5 seconds, the system will automatically search for radio frequencies
again and store the searched frequencies at a different channel sequentially.
Heating system: After the control systems are ready to work, the heater will start working 60 seconds after the
circulation pump is activated, unless the temperature sensor detects that the set temperature is lower than the detected
one. When the water temperature reaches a set temperature, the heater will stop working automatically. When the
water temperature is under 2°of the preset one, the heater will reactivate. The symbol for the heater is located above
the circulation pump symbol , it appears as pulsing bubbles.
NOTE: The heater will not be activated if there is not enough water flow.
Interlocked system between the heater and pumps: Pressing and holding the ON/OFF key again for 20 seconds
will change the system between interlock mode or non-interlock mode (the indicator light on the ON/OFF key shows
RED in interlock mode; while it shows GREEN in non-interlock mode). When in interlock mode, the heater will stop
when you press any of the pump and bubble keys. This feature is meant to reduce the power needed for the spa so that
it can match the power limit of some countries (1 x 16A). In non-interlocked mode, the heater will keep running when
the other pumps are activated unless the water temperature reaches the set temperature. NOTE! That requires at least
a 2-phase connection if the total effect for pumps and heating exceeds 3680 W.
Temperature sensor self-checking system: If E1 is displayed on the panel, then the temperature sensor is
disconnected. In this situation check the wiring of the temperature sensor to see if it’s properly connected. If E0 is
displayed on the panel, then the temperature sensor has short-circuited. In this case, the temperature sensor must be
replaced. The heating system cannot be activated under the two above situations.
Water-lacking protection system for circulation pump and heater: In daily usage, a blockage of the filtration
medium (cartridge filter or filter bag) will eventually occur. A severe blockage will lead to a lack of water for the
filtration pump. Air in the system often leads to the same problem. For instance, during startup if aeration has not been
performed according to the instructions in the manual. When there is a lack of water, the filtration pump and heater
will stop working automatically. At this moment, the symbol of the filtration pump on the control panel will
flash continuously, to remind the user that it is time to clean or replace the filtration medium. After cleaning or
replacing the filtration medium, press ON/OFF several times to expel the air inside the pipe until the filtration pump
works normally.
Anti-freezing system: After power on to enter standby status (the indicator light on ON/OFF key flashes), the
anti-freezing system will be activated instantly. The circulation pump and heating system will automatically stop at the
default temperature of above 10°. When the water temperature in the spa drops below 9°, the circulation pump,
heater and air blower will work automatically, Jet1 (accessory) will automatically start to work in about 85 seconds;
and it will stop after working about 85 seconds; then Jet2 (if equipped) will start to work for about 85 seconds and
stop; finally Jet3 starts to work (if equipped) for about 85 seconds then stops. Pump1, Pump2 and Pump3 will
continuously cycle among themselves. When the detected water temperature reaches 10°, all the pumps and heater
will stop working. When this system is running, the screen background light is on. When the water temperature
reaches 10°, the screen returns to the standby status.
