Setting parameters

With the r.h. rotary selector, select the required zone (from

zone 1 to 7) in the "Specialist" menu level (after entering a

password) and press selector to confirm.

Select the ventilation unit parameter (LM...) you want to

modify, confirm by pressing the selector and then modify

it by turning the r.h. rotary selector. Once you have set the

ventilation unit parameter (LM...) you wanted to modify, press

the r.h. rotary selector again to confirm the setting.
