Smart Winter Mode
Our Smart Winter Mode
protects your system from
the cold by turning pumps on
several times a day to prevent
water from freezing in pipes.
Water temperature regulation
In a regulation cycle, the system
fi rst generates water fl ow
through the heater housing
and the plumbing, in order
to ensure accurate water
temperature readings as well as
avoiding heater activation in dry
conditions.
After verifying pump activation
and taking a water temperature
reading if required, the system
automatically turns the heater
on to reach and maintain water
temperature at Set Point.
Cooldown
After heating the spa water to
the desired Set Point, the
heater is turned off, but its
associated pump (Pump 1 Low-
speed or CP) remains on for a
predetermined period of time
to ensure adequate cooling of
the heating element, this
prolongs its useful life.
The heater icon fl ashes during
this time.
