ENGLISH
The IQ-unit operates as a ‘master’ or brain within Duco's De-
mand-Controlled Natural Ventilation Systems.
It receives and interprets signals from the ‘slave’ components (meas-
urements from a sensor or manual input), based on which it controls
the ventilation system and any external unit. The IQ-unit thus ensures
that stale air, with excessive CO2or moisture content, is exhausted.
The IQ-unit boasts smart functions such as NightBoost and ventilative
cooling, and can also be connected to a building management system
via ModBus.
The IQ-unit can be used in different situations and can perform dif-
ferent functions depending on requirements and the type of central
extract unit:
DucoBox WTW
The IQ-unit controls the DucoBox WTW via the WTW connection.
Pressure-controlled fan
With this the IQ-unit is not connected to the central extract unit. In this
case, the IQ-unit is only required to utilise functions such as ModBus,
NightBoost and ventilative cooling.
Non-pressure-controlled fan
The IQ-unit controls the fan via a PWM connection.
With the IQ-unit, both centrally and zonally controlled exhaust is
available.
1 Application

ENGLISH
*
PWM
With centrally (= not locally) controlled exhaust, air is exhausted in
every air duct connected.
1A. Centrally controlled exhaust

Slave
* Connection between IQ-unit and fan (via PWM) is only applicable when using a non-pressure-
controlled fan.

78
ENGLISH
1B. Zonally controlled exhaust
With zonally (= locally) controlled exhaust, stale air is exhausted only
where necessary, which is conducive to optimum energy-efficiency and
quietness in the ventilation system. This requires a component to be
provided for each zone that acts as a control valve to regulate the ex-
haust air flow rate in that zone. This can be done by providing an Intelli
Air Valve — Duco’s smart control valve — in the duct of each zone, or
using another component with actuator control if the maximum flow
rate through an Intelli Air Valve is insufficient, such as a DucoGrille
Close.

ENGLISH
The IQ-unit is able to communicate with slave components via a wire-
less (RF) or wired link. Both types of communication can be combined
in one system. Wired connections are to be recommended in all cases
of non-residential and other projects where large distances or various
walls and/or building levels need to be spanned.
In addition, connections can also be made via a Switch Sensor (quantity
of 2), PWM-IN and PWM-OUT, WTW and ModBus.

3B. RF (wireless communication)
RF components ( ) have a maximum free-field range of 350 metres.
This distance will be much less in a building because of obstacles
so you will need to allow for features such as walls, concrete and
metal. 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 for-
warded automatically via no more than one other non-battery-pow-
ered component (= hop point). Please refer to information sheet
RF communication (L8000001) at www.duco.eu for further information.
DUCO RF
Power supply 230 VAC
Frequency 868 MHz
Maximum distance 350 m, free field
(less through obstacles)
Maximum number
of components Up to 25 wireless components in a single system

85
ENGLISH
3C. 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 0.8 mm data cable. We strongly advise using
a shielded cable to prevent any interference that may affect the data
communication.
DUCO WIRED
Power supply 24 VDC
Cabling 3-cores of 0,8mm communication (A, B, GND)
Maximum distance up to 300 m
Maximum number
of components Up to 99 wired components in a single system

86
ENGLISH
3D. Various cabling options
WTW
Communication with the DucoBox WTW. In this case a separate 24 VDC
is not required for the IQ-unit.
PWM / 0-10V
PWM-OUT enables communication with a central extract unit or an
actuator such as a Variable Air Volume (VAV) valve.
Its operating mode (PWM or 0-10V) can be changed using the display
menu or the Duco Network Tool. It is set to PWM as standard.
PWM-IN enables the IQ-unit to be controlled like an actuator.
An Actuatorprint is required for each actuator to control multiple actu-
ators independently of one another.
ModBus
Communications with building management systems for instance, for
reading out information as well as controlling the ventilation system.
Please refer to information sheet ModBus (L8000009) at www.duco.eu
for more information.

87
ENGLISH
Switch Sensor
The Switch Sensor can perform one of the following functions when
closing one contact in a two-pole zero voltage contact (only one func-
tion per connection): toilet detection, link to heat pump or overrule
setting. Please refer to information sheet Display menu (L8000015) at
www.duco.eu for more information about its operation.
The contact needs to be closed once in order to pair the component.

88
ENGLISH
Click the IQ-unit onto the DIN rail underneath the DucoBox WTW or
another DIN rail. Use a screwdriver to “prise” the IQ-unit off the rail.

ENGLISH
4B. Air duct connections
Keep resistance down (especially in the bypass duct). Avoid excessive
use of bends. A non-return flap is required when discharging into a
manifold.

90
ENGLISH
In order to enable zonal control, a control valve capable of controlling
the air exhaust from the zone must be utilised in each zone. This can be
done using an Intelli Air Valve or an actuator via Duco’s Actuatorprint.
Intelli Air Valve
This intelligent control valve uses a wired connection with the IQ-unit
and a wireless (RF) connection with the underlying control components.
The Intelli Air Valve can be easily installed in (existing) ventilation
ducts. Please refer to the manual with the Intelli Air Valve for more
information.
5 Zonal control options

91
ENGLISH
Actuator via Duco's Actuatorprint
Actuators can be controlled via Duco’s Actuatorprint. This PCB enables
the IQ-unit to control different actuators separately via a Duco Wired
connection. The Actuatorprint supports PWM, 0-10V, 2 and 3-point
control. The Actuatorprint is available as an external component or is
built into Duco's components such as the DucoGrille Close.

92
ENGLISH
To add, remove or replace components in the network, the system
must be set to ‘Installer mode’. The LED on each component indicates
the active mode of the component (see table below).
‘Installer mode’ can be activated by pressing the IQ-unit ‘INST’ button.
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.
