Table 5: Advanced menu – Sensitive inverter parameters
Home Page The main settings of the system are graphically summed up on the Home Page.
The icon at top left indicates the type of regulation selected.
The icon at centre top indicates the operating mode selected (auto or economy).
The icon at top right indicates the presence of a single
or twin inverter . The rotation of the
icon or indicates which circulation pump is operating.
At the centre of the Home Page is a read-only parameter which can be chosen from a small set of
parameters on Page 8.0 of the menu.
From the Home Page it is possible to access the page for regulating the contrast of the display: hold
down the hidden button, then press and release the right button.
From the Home Page it is also possible to access the read-only menu of the inverter sensitive
parameters set in the factory: hold down the central button for 3 seconds.
Page 1.0
The factory settings are set from Page 1.0 by holding down the left and right buttons at the same time
for 3 seconds.
The resetting of the factory settings will be notified by the appearance of the symbol next to the
word “Default”.
