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.
