1B. Which system do I have?

The capabilities of your ventilation system will depend on the configuration of the system. Please contact your Duco installer

if you don't know which ventilation system you have. A Duco Demand-Controlled Natural Ventilation System consists of the

following:

• Central extract unit

This unit extracts polluted air as required. E.g. a DucoBox.

• Air duct network (not a Duco product)

polluted air is extracted to the central extract unit via ventilation ducts to different rooms.

Note: depending on the configuration of your system, not every room will be ventilated directly. Rooms in which there

is no exhaust duct provided are ventilated via feed-through to other rooms. This can be done for instance with a window

ventilator in internal doors or an air gap under them.

• One or more sensors*

and/or humidity sensors monitor air quality and detect presence. Sensors can be incorporated in a User controller

in the room, or built into air ducts.

• One or more User controllers

For manual operation of the ventilation system.

• Window ventilators

Fresh air is supplied via window ventilators incorporated in windows, window frames, a sliding door or an outside wall.

Your ventilation system may include manual and/or Tronic (= electronically controlled) window ventilators. Manual win-

dow ventilators require to be opened and shut by the user. Tronic window ventilators are electronically controlled window

ventilators which open and shut automatically as the system sees fit.

* Exception: Duco C System

You will need to leave manual window ventilators at least partially open in

order to guarantee automatic system operation.

CENTRAL OR ZONAL EXHAUST?

With central exhaust (= non-local exhaust), ventilation is provided across the entire system. The ventilation system will

therefore exhaust air from all rooms at all times, regardless of where the polluted air is detected or in which room the user

has operated the system. The system therefore has just one zone.

With zonal exhaust (= local exhaust), the system only exhausts polluted air in the zone where it is required. Accordingly, a

User controller will only control the relevant zone, unless the User controller is set to 'master' operation (= operating the

entire system). A zone may consist of one or more rooms (e.g. living room + kitchen).

Note: some settings (see below in this manual) apply only to the room in which the user is located. In central-exhaust sys-

tems, i.e. with just one zone, these settings apply to the whole system.
