01 Introduction

Congratulations on your DucoBox Focus, the smartest box in Europe! The DucoBox Focus performs two functions in a Duco

Demand-Controlled Natural Ventilation System:

On the one hand it is the extractor fan that exhausts contaminated air with excessive CO2content or relative humidity. Thanks to

integrated control valves, air is only exhausted in the zone that requires it.

On the other hand, it is the master or brain of the system. It receives and interprets signals from slave components (measurements

from sensors or manual input), on the basis of which it controls the ventilation system.

It is inadvisable to connect the DucoBox (via a duct or directly) to an extractor hood, regardless of type. This usually causes exces-

sive fouling in the DucoBox, which affects its operation or has a more direct effect on the ﬂow rate.

02 Installation

02.A Positioning

Select a roof pass-through

with low resistance.

0,5 à 1 m

Duct leading to the roof pass-through: use a

reducer 125mm– 160mm. Never use ﬂexible

connections. Avoid curves in this part of the

canalization. If the DucoBox is not mounted in a

protected (insulated) volume, this duct needs to be

thermally insulated.

Use an

acoustic

silencer of

minimum

0.5 to 1 m.

This in every

connection

which leads

to a different

room.

Keep the box airtight. Close

the cover tightly and place

a cap onto any unused

opening.

Avoid as much as

possible the use of

curves. Avoid sharp

angles.

Avoid bumps and dirt in the ducts.

> 90°

160

125 mm → ≥ 30 m³/h

100 mm → < 30 m³/h

< 90°

Reduce the transmission of

vibrations:

• Use Silent Block elements when

ﬁxing the DucoBox to the wall.

• Use duct suspension clamps with

rubber.

Do not place an

exhaust air valve

directly on the box.

Use a 90° bend

between the DucoBox

and the valve. Use

valves with an as low

as possible back-

pressure and follow

the instructions as

given in the manual

regarding the opening

of the valves.

Assure an airtight

connection by using

tape, clamping strips

or tie-wrap. Do not

use screws.

Diameter of the ducts:

125mm upward from 30m³/h

100mm less than 30m³/h

Or an equivalent based on a speciﬁc duct calculation

(p.e. for ducts placed in ﬂoor screed). Make sure that

the total counter pressure in the ducts is as low as

possible (preferably ≤150Pa) and that the airspeed in

every duct does not exceed 3m/s.

DISCLAIMER: no rights can be derived from this document.

All tips are only advisory. All those carrying out

the work can, depending on the project at

hand, determine for themselves which

tips are feasible and/or useful.

The smooth running of your Duco ventilation system is totally dependent

on the choice and the quality of implementation of the duct system!

10 UNMISSABLE TIPS

Has the duct system been optimized? Ask

professional advice from your duct supplier. It

saves you time, ensures quality and provides

energetic advantage for the end user!

L1025000-B 01.06.2018

02.C Air duct

connections

Limit the resistance. A non-return ﬂap is

required when discharging into a manifold.

Position it at least 30cm away from the

DucoBox.

Be sure to take note of the ‘10 unmissa-

ble tips’ as well when ﬁtting the DucoBox.

Avoiding excessive use of bends, especially

angles sharper than 90° and adhering to the

diameter guidelines for the ductwork will

ensure that the ventilation box is able to do

its job satisfactorily. Failure to take account of

this recommendation may result in a highly

energy and maintenance intensive system

that gives rise to excessive noise nuisance

frequently.

RF (wireless communication)

RF components have a maximum free-ﬁeld range of 350 metres. This dis-

tance will be much less in a building because of obstacles. Therefore, you will

need to take objects such as walls, concrete and metal into account. All slave

components (except those which are battery powered) also act as repeaters.

Signals from components that are unable to make a (strong) connection with

the master component are forwarded automatically via no more than one other

non-battery-powered component (= hop). Please refer to information sheet

RFcommunication (L8000018) at www.duco.eu for further information.

Wired (cabled communication)

Wired components can be daisy-chained (= recommended). This means that a

separate cable will not be required for each component. A single central power

supply can be used.

The cable required is a 5x0.75 mm² data cable. We strongly advise using a

shielded cable. This is to prevent any interference that may affect the data com-

munication. Any Tronic window ventilators will be supplied with a 5x0.25 mm²

cable which can be connected via a splicing terminal block.

04 Control valves

The control valves, whether or not they are ﬁtted with a sensor for measuring CO or humidity, can be built into the DucoBox Focus.

Together with the fan, they ensure the correct exhaust air ﬂow rate in the right room.

A control valve with combined CO2and RH measurement can only be used with a DucoBox Focus with a software

version of 11.2 or higher.

A DucoBox Focus can contain up to a maximum of 7 control valves (= one per intake duct). This can be expanded to a maximum of

11 control valves by using the ‘Control Valve Manifold’ (item 0000-4454).

A control valve must always be provided for each ventilation duct connected!

04.A Mounting the control valves

Slide the control valve into the locations

provided in the DucoBox Focus. Connect

the ‘VALVE’ connector on the DucoBox

to IN on the control valve. If applicable,

connect OUT on the valve to IN on another

control valve to be added. At least one

valve must be connected to the DucoBox at

any time. VALVE1 VALVE2

04.B Pairing the control valves

The control valves are paired automatically to the DucoBox whenever ‘installer mode’ is activated (see “Pairing components”

chapter).

04.C Removing / replacing control valves

Taking control valve out temporarily

Follow these steps to take a control valve out of the unit tem-

porarily, e.g. to clean it during maintenance. Make sure that it

is inserted back in the same location. Use the letter labels on

the DucoBox and the relevant valve for this. The DucoBox will

retain all its settings when the control valve is reconnected.

Temporarily removing control valve

1Brieﬂy press the button on the valve to close it

for 15 minutes. The LED will go out.

2Disconnect the wiring.

3Slide the valve out of the DucoBox.

Permanently removing or replacing control valve

To remove a control valve permanently from the system or to replace it (e.g. in the event of a fault) it is important that it should be

deregistered correctly. The DucoBox will not be able to be calibrated correctly if this is not done.

Permanently removing control valve

1Brieﬂy press the button on the valve to drive it shut.

Activate ‘Installer mode’ by pressing ‘INST’ on the

DucoBox. The LEDs on the DucoBox and control

valves will ﬂash green rapidly.

Long-press the button once on the control valve to

be removed in order to remove it from the network.

ATTENTION: any underlying components will also

be removed from the network.

4Disconnect the wiring from the control valve to be

removed and slide it out of the DucoBox.

5Deactivate ‘Installer mode’ by pressing ‘INST’ on the

DucoBox. All LEDs will stop ﬂashing.

Replacing a control valve

1Brieﬂy press the button on the valve to drive it shut.

Activate ‘Installer mode’ by pressing ‘INST’ on the

DucoBox. The LEDs on the DucoBox and control

valves will ﬂash green rapidly.

3Short-press the button twice on the control valve to

be replaced in order to remove it from the network.

4Disconnect the wiring from the control valve to be

replaced and slide it out of the DucoBox.

5Slide the new control valve into the DucoBox and

connect it.

Short-press the button on the new control valve

once. The latter will take on all settings / connec-

tions in the network.

7Deactivate ‘Installer mode’ by pressing ‘INST’ on the

DucoBox. All LEDs will stop ﬂashing.

04.D LED indications

In normal operation, the LED on the control valves will be white

or off, depending on the control valve position. The brightness

of the LED indicates the ﬂow rate through the valve.

06 Electronical installation

06.A Installer / User mode

To add, remove or replace components to the network, the system should be put in ‘Installer mode’. The LED on each component

indicates the active mode of the component (seetable in next section).

‘Installer mode’ can be activated by pressing the DucoBox Focus ‘INST’ button (see drawing in section "03.A Connections &

buttons" on page 5. Once the LED on the master unit starts ﬂashing, it means that ‘Installer mode’ is active. Press ‘INST’ again

to return to ‘User mode’ (LED fully on or off). The system reverts automatically to ‘User mode’ after 15 minutes of inactivity.

06.C Pairing components

The DucoBox Focus is an extractor fan for a zonal ventilation system. This means that ventilation will only operate in the zones

where it is needed (e.g. only in the bathroom while showering) for the most energy-efﬁcient operation. Thus, in the example below,

pressing the button in zone1 will change the ventilation setting only for this zone. Pressing the button on the master user control

will control all zones that are set to ‘AUTO’ at that point in time.

Master user control

This controls the

entire system

Zonal components

These components only control the zone with which they are paired.

ZONE 1

ZONE 2

ZONE 3 ZONE 4

ENGLISH

L2000631 Installation guide for DucoBox Focus (Revision L | 06.09.2022)

It is important that components are paired with the correct zone for this zonal operation. Components can be paired with the

DucoBoxFocus itself (controlling all zones) or with a control valve (controlling a single zone). A component will be paired in every

case with the component (control valve or DucoBox) that is ﬂashing rapidly. It is possible to pair several user controls in one zone,

but not to link one user control to multiple control valves or DucoBoxes.

Never pair more than one system with RF components at the same time. If you do so, a component could be paired

in the wrong network, (e.g. in the neighbours’ DucoBox) or the component may not pair.

With RF components it is recommended to start with the component closest to the DucoBox. This enables this

component to be used as a hop for components that are too distant from the DucoBox and unable to make a direct

RF connection with the DucoBox.

Pairing components

1Activate ‘Installer mode’ by tapping ‘INST’ on the DucoBox. The LED will ﬂash green rapidly.

2Pairing components on the DucoBox:

Use this method for any components that are required to control the entire system (e.g. a master user control).

2a Tap on the button of the component to be paired once while the LED on the DucoBox is ﬂashing rapidly. The LED on

this component will ﬂash red brieﬂy and then start to ﬂash green rapidly.

Pairing components with a control valve:

Use this method for components that only control the zone connected to the control valve duct. Repeat these steps for

each zone.

3a Tap the control valve once so the LED starts to ﬂash green rapidly. Underlying components can now be added in

this zone.

3b Add control components by tapping once on the component to be paired. The LED will ﬂash red brieﬂy and then

start to ﬂash green rapidly.

3c Add any window ventilators by tapping once on the component to be paired. The LED will ﬂash green slowly.

4Once all components have been paired, ‘Installer mode’ can be deactivated by tapping ‘INST’ on the DucoBox Focus. The

LEDs on all components will stop ﬂashing.

Please refer to the manual with the components for more detailed information.
