time. They can be modified, using the keys + and - as follows:
- t0—: set the current year (two figures) from 00 to 99
- t1—: set the current month from 01 to 12
- t2—: set the current day from 01 to 31
- t3—: set the current hour from 00 to 23 (24 hours)
- t4—: set the current minute from 00 to 59
- t5—: set the month of start of summer time from 00 to 12
- t6—: set the month of return to winter time from 01 to 12
After correctly setting each parameter, press the "set" key to
memorize it and move on to the next one. After the last param-
eter (t6—), you will automatically exit the programming proce-
dure, but if necessary you can return to it by pressing the "clock"
key (7) for about 1-2 seconds.
You can also exit the programming procedure by pressing any
key that is not lit (except "start"), or you can wait 30 seconds
without touching any key ("timeout" time).
At three o'clock on the last Sunday of the month set in "t5",
changeover to summer time will occur. At three o'clock on the
last Sunday of the month set in "t6", changeover back to winter
time will occur. If "t5" is set to 0, no time change will occur, even
if "t6" is set to something other than 0
Display of date and time
To check the memorized time and date, proceed as follows:
Press the "start" key (3). The corresponding LED will come
on. The display will show the current temperature of the water in
the tub.
Starting from this water temperature, read by the sensor in
the pipe of the filter, repeatedly press the "hand" key to view, in
order, the following data:
- SP—: this is the temperature you want the water in the hot-
tub to reach (in °C, or °F), i.e. the "set point" (this value can be
modified using the keys "+" and "-").
- hh.mm: current time, in hours (00÷23) and minutes, with
dot in middle flashing once per second.
- gg.mm: current date, in day-month format.
- aaaa: current year, in complete format (4 numerals).
During the previously mentioned scanning, the date and time
cannot be modified. To modify them, you must shut down the
system using the "start" key and proceed as described in the pre-
vious paragraph on setting the date and time.

ETTING GENERAL SYSTEM PARAMETERS
With the control panel, you can set the general parameters used by
the system to manage all available functions. Some of these param-
eters can be set/modified also using other procedures, while others
can only be set/modified using the procedures described below:

To access the general system parameters, the system must
be in the "standing by for commands" condition, i.e. powered
on but with the "start" key (3) off.
Press and hold for about 1-2 seconds the "light bulb" key
(6). The corresponding LED will come on as will those for the
keys "+" (8), "-" (5) and "set" (9), while the display will show the
first parameter (P0-). Repeatedly press the "set" key, and you will
see in rapid succession all the general system parameters which
can be modified from their default settings using the keys "+"
and "-".
The following table shows the effect of the aforementioned
parameters on the system, based on the value set, and which
devices and/or functions are involved.
- P0(-): system control mode (default=1).
If =0 the push buttons are active; if =1 the control panel
mounted on the electronic box is active. This parameter can
also be changed by pressing and holding, in "active" status,
the "hand" key (see the chapter on the management of func-
tions via the control panel).
- P1(-): timer status, for management of filtering and heating
of water (default=1).
If =0 the setting of the timer is disregarded. If =1 the cycles
for filtering and heating of the water refer to the timer data.
Timer modification from 0 (off ) to 1 (on), and vice versa, can
also occur with the system in "active" status, by pressing the
"clock" key. If the LED of the "clock" key is on, it is the equiva-
lent of "1/on".
- P2(-): "set point" for water heating temperature (default 36
°C, or 97 °F).
This can be modified from 15 °C to 40 °C (59÷104 °F). The pa-
rameter can be also be modified with the system in "active"
status, by pressing the "hand" key and using the keys "+" and
"-" (see chapter on display of date/time).
- P3(-): "set point" hysteresis (default 1 °C, or 2 °F).
The heater is not activated until the water temperature
drops below this value, with respect to the established set
point. It can be modified from 0.5 °C to 3 °C (1÷6 °F).
- P4(-): automatic activation time of hydromassage pumps
and blower (default 0).
This is a special function that is active only with P0=1 (i.e.
push buttons disabled). It is described in further detail in sub-
sequent chapters on the hydromassage and blower. You can
set from 01 to 99 minutes of continuous and cyclical opera-
tion of the devices mentioned. If set to 0 the automatic func-
tion is disabled.
- P5(-): interval of time for automatic reactivation of hydro-
massage pumps and blowers as referred to in point P4. If
P4=0 no value may be loaded on P5; if P4 is different than
0, values may be loaded inclusive between 0 and 99 (15 is
proposed as default).
- P6(-): "timeout" of operation of hydromassage and blower
