Page 4: Application
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. -
Page 5: Centrally Controlled Exhaust
ENGLISH Centrally controlled exhaust With centrally (= not locally) controlled exhaust, air is exhausted in every air duct connected. Master Slave * Connection between IQ-unit and fan (via PWM) is only applicable when using a non-pressure- controlled fan. -
Page 6: Zonally Controlled Exhaust
Intelli Air Valve is insufficient, such as a DucoGrille Close. Master Slave * Connection between IQ-unit and fan (via PWM) is only applicable when using a non-pressure- controlled fan. -

Page 9: Cabling
ENGLISH Cabling 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. -

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. - Page 15 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.

ENGLISH Installation Mounting 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. DucoBox WTW Din Rail... -
Page 17: Air Duct Connections
ENGLISH 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. -
Page 18: Zonal Control Options
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. - Page 19 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...

Page 26: Other Operations
In order to remove all components from the network (e.g. in the event of problems) you can press and hold ‘INST’ until the LED starts flash- ing red. The IQ-unit will then reboot (around 15 seconds) and the LED will stop flashing. -
Page 27: Configuration
The system needs to be configured for it to work correctly. This will ensure its operation is as quiet and as energy-efficient as possible. See under the Tools heading at www.duco.eu for info about determining ventilation flow rates. Configuration takes place in two stages: setting exhaust vents and actual configuration. - Page 28 ENGLISH DUCOVENT DUCOVENT BASIC DESIGN AND OTHER VENTS 100% 75 m3/h open 50 m3/h open 25 m3/h open Foam...

- Page 32 This can be done using the arrow keys on the IQ-unit if it has been connected to it (via PWM or WTW). If the zone is fitted with a constant volume control, the point must be found at which the fan runs as slow as possible while attaining the desired flow rate.
- Page 33 Measure any remaining vents within the current zone and fine- tune them using the exhaust vent. Work from highest to lowest flow rate. Exit configuration mode by pressing ‘HIGH’ on the iAV Control valve or on the IQ-unit.
