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.

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

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

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.
