"WATER IS BELOW SET-TEMP"
If the spa water temperature is 6°C lower than the set temperature
the recirculation pump and heater are automatically activated to
guarantee the anti-freezing protection. The spa remains in this mode
until the water temperature is 9°C lower than the set temperature.
I
No corrective action is required.

tric box is defective.

I
If there is not a noise (relative to the possible functioning of
the electro-mechanical parts) or if there is a continuous hum, dis-
connect the spa (the pump could be incorrectly primed; refer to
the "The pump does not operate" chapter).

may appear the first time the spa is filled, seeing that the water

N.B.: in the instance where the protective function "freeze
protection" is active, it is not possible to action the pumps via the
