9.8. OPERATING MODES
The "full or little" mode
(if the jumper is present on the main module) or the "full or none" mode (if the jumper is pulled out on the main module) is
obtained by pressing the "memory" button on the main module for between 10 and 15 seconds.

The "chrono-proportional" mode
is obtai-
ned by pressing the "memory" button on the
main module for between 5 and 10 seconds.

or
Operation in the "full or little" mode, for example with a CO2 threshold regulation at 700 ppm
Just as for the "full or little" mode, the flow diminishes every 10 mins a maximum of 10% (in order to ventilate the premises sufficiently after all the occu-
pants have left). But where necessary it can increase by n x 10% in the following cycle, according to requirements.
