ENGLISH
The IQ-unit operates as a ‘master’ or brain within Duco's Demand-Controlled Natural Ventilation Systems.
It receives and interprets signals from the ‘slave’ components (measurements 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 CO2 or 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 different 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.

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 exhaust 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 wireless (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.

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 forwarded automatically via no more than one other non-battery-powered component (= hop point). Please refer to information sheet
RF communication (L8000001) at www.duco.eu for further information.
