2.3 Heating
When the spa water temperature measured by the heater sensor falls below the setpoint value, the
pump and heater start up simultaneously and automatically. The heater runs until the water temperature
reaches the setpoint value (if this occurs during a filtration cycle, the pump will continue to run).
NOTA BENE : If the ambient temperature is high (for example during the summer), the water temperature
may spontaneously rise above the setpoint temperature selected by the user (e.g. : setpoint temperature
= 35°C, ambient temperature = 40°C, water temperature = 37°C).
Besides periodic partial replacement of the spa water with cool fresh water, the only way to minimise this
phenomenon is to respect the following rules :
• Select a setpoint temperature well below the desired temperature
• During the day, cover the spa while it is not in use to limit heating by the sun
• Minimise the length of the filtration cycle: the less the pump runs, the less the water will be heated
by mixing
• If the temperature drops at night, uncover the spa so that the water can cool down during the night.
3. PUMP OPERATION
This spa is fitted with a two-speed pump, the user selects the operating mode using the 'PUMP' key.
Press the " PUMP " key repeatedly to cycle through the following operating modes
If the pump is in manual or standby (stop) mode, it automatically switches to "AUTO" mode after 1h30.
While the pump is running at high speed, the heater switches off to avoid excessive consumption of
electrical power that could overheat the circuitry.
In "AUTO" mode, the pump runs at low speed.
