Adjustment Of Water Heating Temperature (Set Point); Maintaining A Minimum Temperature Of The Water; Isetting Of Filtering And Heating Cycles; (Timer Parameters) - Jacuzzi ALIMIA Manuel D'installation

3°C.To do this, proceed in the same manner as described above,
modifying the values associated with parameter P3- (chapter on
setting general system parameters).
To ensure precise measurement of the water in the tub, the
filtering pump is started up once every half hour (see the chap-
ter on water filtering), since the temperature probe is inserted
in the pipe that goes to the filter.

Adjustment of water heating temperature (set point)

To check or modify the water heating temperature, do the following:
Press the "start" key (3). The corresponding LED will come on.
The display will show the current temperature of the water in the
tub. However, if the system is turned on at that moment, the fil-
tering pump is automatically started up, and the actual temper-
ature of the water will be shown after about two minutes (shown
in °C, or °F as programmed, see the chapter on setting gen-
eral parameters).
Press the "hand" key to show the parameter:
- SP—: is the temperature you want the water in the spa to reach(in
°C or °F), i.e. the set point.
When this message appears, the keys "+" and "-" also light up.
You can use them to modify the memorized temperature set point
from a minimum of 15 °C to a maximum of 40 °C (59÷104 °F).
To show the temperature of the water in the tub again, just do not
touch any key for about 30 seconds, or repeatedly press the "set" key.
Note: if the temperature is set to °F, values above 99°F will still be
shown in two figures, and the small dot at lower right will light up.

Maintaining a minimum temperature of the water

If water heating is deactivated or if the outdoor temperature is
very low, associated with water heating programmes that are too
brief, the temperature of the water may drop to levels that are too
low and/or undesirable.
At least once every half hour, the system reads the actual tem-
perature of the water in the tub (see the chapter on water filter-
ing), even if no water filtering or heating cycles have been pro-
grammed. If the water temperature drops below the minimum set
temperature, the heater and the filtering pump are activated auto-
matically until the temperature returns above that value.
The memorized default minimum temperature is 15°C, but
this can be modified by entering the procedure for modifying
general system parameters (parameter PA-, see corresponding
chapter).
The aforementioned programme for maintaining the minimum
temperature is equipped with additional safeties, for example if
there is a failure of the heater.
If the water temperature drops below 10°C, the pumps and
the blower come on for 30 seconds every hour. If the tempera-
ture drops below 5°C, the pumps and blower continue running
until the temperature is once again greater than 7°C (antifreeze
protection).

SETTING OF FILTERING AND HEATING CYCLES

(TIMER PARAMETERS)

To enter the procedure for programming timer parameters,
press and hold the "clock" key (7) for about 1-2 seconds. The
corresponding LED will come on as will those of the keys "+"
(8), "-" (5) and "set" (9), while the display will show the first
parameter (A0—).
N.B.: the system must be in "standing by for commands" condi-
tion, i.e. with the "start" key (3) off.
The system parameters that can be set are "On" (always
on), "di" (deactivated), and cycle start time, to be associated with
a cycle end time (up to a maximum of three).
Press the "set" key repeatedly to view the following param-
eters, which can be modified using the keys "+" and "-":
- A0—: filtering mode, which can be "On" (always on), "di" (deac-
tivated), "—" (start time of first filtering cycle; no fractions of hours).
The default setting is "On".
- A1—: end time of first filtering cycle "—", which must necessarily
be greater than the start time.
It cannot be modified if A0 = "On" or "di".
- A2—: start time of second filtering cycle "—".
The same notes are valid as for point A1.
- A3—: end time of second filtering cycle "—".
The same notes are valid as for point A1.
- A4—: start time of third filtering cycle "—".
The same notes are valid as for point A1.
- A5—: end time of third filtering cycle "—".
The same notes are valid as for point A1.
- b0—: method of heating, which can be "On" (always on), "di" (deac-
tivated), "—" (start time of first heating cycle; no fractions of hours).
The default setting is "—" (07).
- b1—: end time of first heating cycle "—", which must necessarily
be greater than the start time (default=18)
It cannot be modified if b0 = "On" or "di".
- b2—: start time of second heating cycle "—".
The same notes are valid as for point b1.
- b3—: end time of second heating cycle "—".
The same notes are valid as for point b1.
- b4—: start time of third heating cycle "—".
The same notes are valid as for point b1.
- b5—: end time of third heating cycle "—" .
The same notes are valid as for point b1.
When the last of the parameters is confirmed, (b5—), the
time and date parameters are proposed (see the chapter on
