User manual for Duco's ventilation systems
Temporary manual setting
A temporary setting is activated for the zone in which the user is located. The temporary setting has a standard duration of
15 minutes* for zones without Tronic window ventilators and 8 hours* for zones with Tronic window ventilators. Pressing
2 or 3 times multiplies this time correspondingly. E.g. Pressing 3 times in a zone without Tronic window ventilators will
put the system in the high setting for 3 x 15 = 45 minutes. The system will revert to the automatic setting thereafter.
* The stated times are standard and may differ in line with system settings.
Note: In the medium and high settings, ensure that manual window ventilators are open. Any Tronic window ventilators will
open automatically.
These settings are permanent in a Duco C system.
In view of the fact that a Duco C system does not have an automatic mode available, the ‘AUTO’ button has the
following function: Press the button 1, 2 or 3 times to put the system in a temporary high setting for 15, 30 or 45
minutes* respectively. The system will revert thereafter automatically to the setting last selected.
* These times are standard and may differ in line with system settings.
In older systems, these times are 10, 20 and 30 minutes as standard.
