(Revision K | 13.07.2020) Master Slave 01 Introduction Congratulations on your DucoBox Focus, the smartest box in Europe! The DucoBox Focus performs two functions in a Duco De- mand-Controlled Natural Ventilation System: On the one hand it is the extractor fan that exhausts contaminated air with excessive CO2 content 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 system master or brain of the system. It receives and interprets signals from slave components (meas- urements 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 output.

(Revision K | 13.07.2020) ≥ 200 kg / m² 03 Fitting 03.A Position 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 mm 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. 1 7 8 9 10 2 3 4 5 6 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 03.C Air duct connections Keep down restriction. A non-return flap is required when discharging into a manifold. Position it at least 30 cm away from the Duco- Box. Be sure to take note of the ‘10 unmissable tips’ as well when fitting the DucoBox. Avoid- ing excessive use of bends, especially angles sharper than 90° and adhering to the diam- eter 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 frequent excessive noise levels. 03.B Fixing

(Revision K | 13.07.2020) 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. Therefor 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-bat- tery-powered component (= hop point). Please refer to information sheet RF communication (L8000018) at www.duco.eu for further information. DUCO RF Power supply 230 VAC Wiring 1,5 mm² 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 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 shield- ed cable. This is to prevent any interference that may affect the data communi- cation. Any Tronic grilles will be supplied with a 5 x 0.25 mm² cable which can be connected via a splicing terminal block. DUCO WIRED Power supply 24 VDC Wiring 5 x 0.75 mm² (5 x 0.25 mm² from Tronic grilles) Maximum distance up to 300 m Maximum number of components Up to 99 wired components in a single system 05 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 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 requires to be provided in every case for each ventilation duct connected! 05.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 anoth- er control valve to be added. At least one valve must be connected to the DucoBox at any time.

(Revision K | 13.07.2020) 05.B Pairing the control valves The control valves are paired automatically to the DucoBox whenever ‘installer mode’ is activated (see “Pairing components” chap- ter). 05.C Removing / replacing a control valve Taking control valve out temporarily Follow these steps to take a control valve out of the unit temporarily, e.g. to clean it during maintenance. Take care to ensure 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 1 Short-press the valve button in order to drive it shut for 15 minutes. The LED will go out. 2 Disconnect the wiring. 3 Slide 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 paired correctly. The DucoBox will not be able to be calibrated correctly if this is not done. Permanently removing control valve 1 Short-press the valve button in order to drive it shut. 2 Activate ‘Installer mode’ by pressing ‘INST’ on the DucoBox. The LEDs on the DucoBox and control valves will flash green rapidly. 3 Long-press the button once on the control valve to be removed in order to remove it from the network. NB: any underlying components will also be removed from the network. 4 Disconnect the wiring from the control valve to be removed and slide it out of the DucoBox. 5 Deactivate ‘Installer mode’ by pressing ‘INST’ on the DucoBox. All LEDs will stop flashing. Replacing a control valve 1 Short-press the valve button in order to drive it shut. 2 Activate ‘Installer mode’ by pressing ‘INST’ on the DucoBox. The LEDs on the DucoBox and control valves will flash green rapidly. 3 Short-press the button twice on the control valve to be replaced in order to remove it from the network. 4 Disconnect the wiring from the control valve to be replaced and slide it out of the DucoBox. 5 Slide the new control valve into the DucoBox and connect it. 6 Short-press the button on the new control valve once. The latter will take on all settings / connec- tions in the network. 7 Deactivate ‘Installer mode’ by pressing ‘INST’ on the DucoBox. All LEDs will stop flashing. 05.D LED indications The LED on the control valves will be white or off in normal operation, depending on the control valve position. The bright- ness of the LED indicates the flow rate through the valve. Please refer to “07.B LED indications on page 12 for the meaning of the remaining LED colours. Valve open = max air flow LED Valve shut = lowest air flow LED

(Revision K | 13.07.2020) 07 Electronical installation 07.A Installer / User mode To add components to the network, remove or replace, 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 "04.A Connections & but- tons" on page 8.) 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. 07.B LED indications DucoBox Focus RED (blinking slowly) Not in network RED (blinking rapidly) Logging in GREEN (blinking slowly) In network GREEN (blinking rapidly) In network, waiting for associated components YELLOW (blinking slowly) Transitional phase (please wait) YELLOW (on) Initialising (system configuration in progress) WHITE or OFF Normal BLUE Component is displayed if changes are being put through via the master. ORANGE The system is not working correctly because the DucoBox has not been calibrated. Restart the box. Follow the guidelines in ‘10 essential tips’ if the problem recurs continually. 07.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 ZONE 1 ZONE 2 ZONE 3 ZONE 4 Zonal components These components only control the zone with which they are paired.

(Revision K | 13.07.2020) 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 multiple 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 point for components that are too distant from the DucoBox and unable to make a direct RF connection with the DucoBox. Pairing components 1 Activate ‘Installer mode’ by tapping ‘INST’ on the DucoBox. The LED will flash green rapidly. 2 Pairing 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 once on the button of the component to be paired 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. 3 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. 4 Once all components have been paired, ‘Installer mode’ can be deactivated by tapping ‘INST’ on the DucoBox Focus. LEDs on all components will stop flashing. Please refer to the manual with the components for more detailed information.

(Revision K | 13.07.2020) 07.D Removing / replacing components Removing paired components from the network or replacing is only possible within 30 minutes after the component is paired in or is restarted. Restarting can be done by disconnecting the power for a moment. After a time-span of 30 minutes, remove and replace operations are ignored. This is valid for all components from date of manufacture 170323. Removing a component 1 Activate ‘Installer mode’ by long-pressing 2 diagonal buttons on a paired control. The LED will flash green or yellow rapidly. 5 sec 2 Press once and hold a button on the component to be removed in order to remove it from the net- work. NB: any underlying compo- nents will also be removed from the network. 5 sec 3 Deactivate ‘Installer mode’ by pressing the 4 buttons on a paired control simultaneously (or using the palm of your hand on a control featuring touch buttons). The LED will turn white. Replacing a component 1 Activate ‘Installer mode’ by long-pressing 2 diagonal buttons on a paired control. The LED will flash green or yellow rapidly. 5 sec 2 Press briefly twice on the button of the component to be replaced. 2x OLD 3 Tap once on the button for the new component. The latter will take on all settings / connections in the network. 1x NEW 3 Deactivate ‘Installer mode’ by pressing the 4 buttons on a paired control simultaneously (or using the palm of your hand on a control featuring touch buttons). The LED will turn white. 07.E Tips • Removing all components from the network (e.g. in the event of problems): Activate ‘Installer mode’ and long-press ‘INST’ until the LED starts flashing red. The DucoBox will reboot and the LED will stop flashing. • Restoring factory settings for the DucoBox and all paired components (AS FROM DucoBox version 18xxxx): Long-press ‘INST’ and ‘ENTER’ if not in ‘Installer mode’. The network remains in place. • Use the Duco Network Tool to read out information from components.

(Revision K | 13.07.2020) 08 Air calibration The system needs to be configured for it to work correctly. This will ensure its operation is as quiet as possible and energy-efficient. See under the Tools heading at www.duco.eu for information about determining ventilation flow rates. 08.A Air calibration procedure for DucoBox Focus The configuration procedure must be carried out on a calm day (no more than wind force 2: leaves rustling, feeling the wind in one’s face). DucoBox Focus air calibration 1 The exhaust vents must be set depending on the situation. Proper pre-setting makes for rapid and correct configuration. SITUATION 1 : one vent per valve Set all vents to the fully open position, regardless of the desired flow rate. When using DucoVent Design exhaust vents, leave the outer ring in place for acoustic effect. SITUATION 2 : Multiple vents per valve with equal flow rates Set all vents to the fully open position, regardless of the desired flow rate. Set the valve to the sum of the vent flow rates via the display menu or the Duco Network Tool. Example: 2 vents, 50 m³/h each → set valve to 100 m³/h. 100 m3/h + = SITUATION 3 : Multiple vents per valve with different flow rates Set the exhaust vents so they match the desired flow rate in line with the table below. Set the valve to the sum of the vent flow rates via the display menu or the Duco Network Tool. Example 25 m³/h vent and 75 m³/h vent → set valve to 100 m³/h. 100 m3/h + = When using DucoVent Design exhaust vents, always leave the outer ring in place for acoustic effect. Flow rate DucoVent Design DucoVent Basic and other vents 75m3/h 100% open 50m3/h 50% open 25m3/h 25% open

(Revision K | 13.07.2020) 2 Before activating air calibration mode: • Close all windows and doors. • Ensure that all duct openings in the DucoBox are fully closed and that the DucoBox cover is closed! • Avoid air leaks in the ventilation ducts. • Set all window ventilators to the open position. Any Tronic ventilators will open automatically. open 3 Pull the plug out of the socket and wait a few seconds. 4 Put the plug back into the socket. The DucoBox will be configured automatically on start-up. Calibration takes 30 seconds + 1 minute per connected control valve. * Depending on the software version of the User controller / CO2/Humidity sensor. 08.B Checking The steps set out below can be used to check whether flow rates have been set correctly. Checking configured flow rate 1 Open the DucoBox cover. 2 Press ‘HIGH’ briefly. The DucoBox will remain in configuration mode for 30 min- utes (as standard). 3 Close the cover. 4 Wait at least one minute to allow the ventilation system to stabilise. 5 Measure the vents. If a flow rate differs from the desired output, this can be ad- justed via the display menu or using the Duco Network Tool. 6 If you finish before the standard setting of 30 minutes, re-open the DucoBox cover and press ‘HIGH’ again. Then replace the cover on the DucoBox.
