A) PROPORTIONAL / AUTOMATIC SETTING
A The opening and closing movement of the damper or grille will be automatic from position to position, based on the
set temperature (E.g.: If 20 °C is set and in the room it is 30 °C, all the vanes will open up to 100% Afor faster cooling,
if instead in the room it is 22 °C, the vanes will open at 33% A because the temperature is close to the set value).
Therefore: the greater the difference between the two values, the more the vanes of the damper or grille will open; the
lesser the difference between the values, the more the vanes will close and eventually completely shut. The positions
are highlighted by the symbol of the vanes with the letter A A
(automatic operation). Function not recommended if you use the motorised grille.
Procedure:
B) MANUAL OPENING SETTING
The opening will take place in the set position from the three options: A(100% open) A (66% open) (33% open)
until the set temperature is reached. The damper or grille closes completely to reach the set temperature and will display
the symbol of the closed damper . The set xed position is recommended for the installation of motorised grilles,
insofar as it is possible to select the position of the adjustable vanes and therefore the direction of the air ow. Moreover,
with circular dampers it is also useful in dening the different air ows of each room.
