System choice.
“
SySt
” parameter (Default value “
1
” cannot be modified).
System 1.
Base system, with 1 tank, 1 pump, series of manifolds and 2
sensors. It can be enriched with extra functions with 1 or 2
sensors T3 (NTC) or T4 (PT1000) (Thermostat, Cooling, An-
ti-stagnation or diff Control function).

Tank 1 charging is possible if the temperature difference “
dt
"
between the collector (T1) and tank 1 (T2) is sufficient.
Choice of the manifold.
“
TubE
” parameter (Default value “off”).
Once the “
TubE
” parameter has been selected, press the naviga-
tion key to the right (▶+) to choose the type of manifold installed.
- At this point select “on” if your system uses a vacuum pipe
manifold. (This function can also be used with a flat manifold if
the sensor is mounted on the outer parts of the manifold). This
function works as follows. Every 30 minutes the pump runs
for 40 seconds to measure the correct value on the manifold
and avoid a cycle with short charge.
- Select "off" if the system works with a flat manifold under
normal conditions of use.
Manifold maximum temperature.
“
ColM
” parameter (Default value “120”).
- Set the level to start the overheating protection for the man-
ifold (Adjustable from 110 to 150°C, with factory setting at
120°C).
Overheating protection.
“
OvrH
” parameter (Default value “On”).
This function will stop the circulations of all manifolds (P1 and
P2) when the manifold temperature increases above “
ColM
”
plus a compensation value (default value +10°C, modifiable).
This function is used to protect the system elements (pipes,
fittings, ring seals ..).
- To activate the function press (▶+) selecting "on”.
- The compensation level can now be adjusted.
“
Ovrt
” parameter (Default value “20°C”).
This compensation is generally used to avoid a too fast reaction
of the overheating protection function (especially useful with
the vacuum pipe manifold).
(Adjustable from +10°C to +30°C with factory value +10°C).
N.B .: for safety reasons, the overheating protection must
always be “on”.
Cooling.
“
Cool
” parameter (Default value “On”).
This option is used to protect the manifold liquid and works
as described below. It activates the solar pump
P1
or
P2
if the
temperature on the series of manifolds
T1
or
T4
exceeds the
“
Max temp
” value even if the maximum temperature set in the
tank is exceeded. Circulation stops when the temperature has
dropped by 10°C (The pumps stop if the water temperature in
the tank reaches 90°C).
“
Rcoo
” parameter (Default value “On”).
When the water temperature in the tank exceeds the "Maxtemp
tank1" setting level and the manifold temperature has dropped by
10°C, the pump is activated to cool the tank through manifolds.
The pump will turn off when the water temperature drops to the
"
tkM1
" setting level or when the difference between the tem-
perature of the series of manifolds and the tank is less than 2°C.
Anti-freeze protection.
“
FrEZ
” parameter (Default value “off”).
This option keeps the temperature of the solar panel
T1
or
T4
above the level set for frost with the “
Frzt
” parameter by acti-
vating pump
P1
or
P2
.
This option can be used to reduce the accumulation of snow on
the panel and increase efficiency during the day or avoid damage
to the solar liquid.
N.B .: it is preferable not to use this function in areas that are
too cold to avoid using too much energy stored in the tank.
- To activate the function, press (▶+) and select "on”.
- The Freeze setting level can now be adjusted.
“
FrZt
” parameter (default value “10°C” (Adjustable from -20°C
to + 7°C with recommended value 3°C).
Display.
“
DiSP
” parameter (Default value “OFF”).
Backlight function.
- To disable or disable the backlight function, press (▶+) or (-◀).
- If it is “
Off
” the backlight will turn off automatically 3 minutes
after pressing the button.
- If it is “
On
” the backlight will always be active.
Factory setting.
“
Fact
” parameter.
- If you want to reload all the parameters with the factory values,
hold down the (▶+) key for a few seconds.
N.B.: for reasons of protection from errors and security rea-
sons, the chosen system will not be reset.
Setting menu (setting)
In this menu you have all the adjustable parameters for your
system. The various parameters are not available on all systems.
To access the Setting menu, press the (-◀) and (▶+) keys simul-
taneously. Once you have entered the Installation menu (the first
parameter “
TkM1
” is displayed), it is possible to choose another
parameter by pressing the navigation key (
OK
).
Once the desired parameter is displayed, it is possible to change
