1.17 SOLAR CONTROL UNIT INSTALLATION.
To access the solar control unit connection, it is necessary to re-
move the contact cover by unscrewing the relevant fixing screw
(Fig. 26) and access the connections area.
DESCRIPTION OF THE SOLAR CONTROL UNIT CON-
TROLS.
1: The solar power storage tank is in operation.
2: Simplified system drawing.
- The pump logos switch on when they are activated.
- The solid triangles on the valve logo indicate circulation.
- The inside of the tank is active during filling.
3: Operating mode setting.
4: Name of the value or parameter displayed under number "5".
5: Temperature of the various sensors or value of the parameter
displayed under number "4".
A: Keypad description:
Plus key (▶+);
Minus key (-◀);
Confirmation key or menu navigation key (OK).
N.B.: on the main screen you can select the sensor that must always
be displayed; press the (OK) key to display the desired sensor.
Installation menu.
Press the (OK) key for 5 seconds to access the installation menu.
When you access the installation menu (the first parameter "Syst"
is displayed), it is possible to select another parameter by pressing
the (OK) navigation key.
Once the desired parameter is displayed, it is possible to change
the value using the keys (▶+) or (-◀).
Block function.
To prevent errors after installation, all the critical parameters
(system and Extra function) cannot be accessed when over 4 hours
have elapsed after start-up. If you wish to edit them, disconnect
and reconnect the control unit. No settings are lost during dis-
connection or after a blackout.
After 4 hours it is possible to change all the other settings to
optimise the system.

1.18 SYSTEM SELECTION.
"SySt" parameter (Default value "6" not editable).
System 6.
Base system with 1 series of manifolds, 1 solar tank, 2 pumps/
circulators, 1 external heat exchanger. It can be enriched by an
extra function with 1 T3 (NTC) sensor (Thermostat, Cooling,
Anti-stagnation).
1.19 MANIFOLD SELECTION.
"TubE" parameter (Default value "off ").
After selecting the "TubE" parameter, press the navigation key to
the right (▶+) to select the type of manifold installed.
- Now select "on" if your system uses a manifold with vacuum
pipes. (This function can also be used with a flat manifold if the
sensor is mounted on the outside of the manifold). This function
works as follows. Every 30 minutes the pump is activated for
40 seconds to measure the correct value on the manifold and
prevent a short charging cycle.
- Select "off " if the system works with a flat manifold in normal
operating conditions.
1.20 MAXIMUM MANIFOLD TEMPERATURE.
"ColM" parameter (default value "120").
- Set the level to start the overheating protection for the manifold.
(Adjustable between 110 and 150°C, with default value 120°C)
