Press the "Light" key one more time to exit the procedure
and memorize the new values. The display will go off for a mo-
ment, and then it will come on again.
To go back to the Celsius scale (°C), return to the procedure and
set figure "x" of the parameter I1x to 0.
NOTE: If no key is pressed for 20 seconds, you will exit the proce-
dure and any changes made will not be saved.
Water heating temperature ("set point").
To check or modify the water heating temperature, do the following:
Press the key "Up/Down"
rently memorized temperature (in °C or °F as programmed; see
"Unit of measurement of the temperature").
Press the key "Up/Down"
value from a minimum of 15 °C to a maximum of 40 °C (59÷104 °F).
NOTE: if you press the upper part of the key, the displayed value
increases. If you press the lower part, it decreases.
If the display is equipped with two separate keys, press the key
"Up" to increase the value or the key "Down" to decrease it.
To show the temperature of the water in the tub again, do
not touch any key for about 5 seconds.
As soon as the water temperature set point is reached, the
heater is shut off. It will not be turned back on until the water
temperature drops about 0.5 °C (1 °F) below the set point.
To ensure precise measurement of the water temperature,
the pump is turned on at low speed (or the filtering pump,
where present), approx. every half hour and for 30" (even if filter-
ing cycles are not set), since the temperature probe is located in
the heater pipe.

When the system is turned off, or there is a power outage, the last
set point is stored in memory.
Operation of the heater is shown on the display by a LED on
steady under the symbol
has been suspended to keep from exceeding the maximum permit-
ted consumption. See also the previous note.
For informational purposes, the 2 kW electric heater raises the
temperature of 1 m 3 of water by approx. 1.7 °C in 1 hour, considering
the thermal cover on the hot tub and disregarding system heat loss.
CAUTION
Do not use the hot tub if the water temperature is 40 °C or
more.
Maintenance of minimum temperature of water in tub and
anti-freeze protection of the pipes ("Smart Winter").
At regular intervals, the system reads the actual temperature. If
it is below the minimum admissible value (15 °C - 59 °F), the heater
and the filtering pump are automatically activated until the tem-
perature rises above that value.
"Smart Winter" mode lets you make use of a special probe to
monitor the temperature of the compartment under the tub, which
contains the all of the pipes of the plumbing circuit. In extreme
conditions, the system may turn on this protection (indicated on
the display by the message ICE), switching on the pump(s) and the
blower (where present).
In the case of the models in which the limitation of electrical con-
sumption has been enabled, the heater will be off during the first
phase of the cycle, but will be activated subsequently.
The pump(s) (and the blower) are turned on at preset inter-
vals, depending on the temperature:
