01 Introduction
The DucoBox Reno, the most compact ventilation unit in Europe, performs two functions in a DUCO Demand-Controlled Natural
Ventilation System.
On the one hand, it is the master, or brain of the system. It receives and interprets signals from slave components (measurements
from sensors or manual input), on the basis of which it controls the ventilation system.
On the other hand, it is the extractor fan that exhausts stale air with excessive CO2content or humidity.
CO2levels are measured via optional CO2sensors; the humidity level is measured via a standard RH sensor integrated in the box
itself.
DUCO advises against connecting the DucoBox (via a duct or directly) to an extractor hood, regardless of the type. This usually
causes excessive fouling in the DucoBox, which affects its operation or has a more direct effect on output.

02.C Air duct connections
Limit the resistance. A non-return flap is required when discharging into a manifold.
Be sure to take note of the ‘10 unmissable tips’ as well when mounting the DucoBox. Avoiding excessive use of bends, especially
angles greater than 90° and adhering to the diameter 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 excessive noise nuisance frequently.
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 blocks 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.

Wireless communication
The DucoBox Reno is able to communicate with DUCO slave components via a wireless (RF) connection.
RF obstacle-free zone
Do not place any obstacles causing RF interference or other
devices with an RF connection within a radius of at least 30 cm
around the RF component. We take these to include items such
as washing machines, tumble dryers, ironing boards, etc.

Figure 9: Communication via RF
RF components have a maximum free-field range of 350 metres. This distance will be much less in a building because of obstacles.
Therefore, you will need to take objects such as walls, concrete and metal into account. 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). Please refer to
information sheet RF communication (L8000018) at www.duco.eu for further information.

04.B CO2Box sensor
A CO2Box sensor can be integrated into a duct port of the DucoBox Reno and provide measurement in an air duct. A DucoBox Reno
can contain a maximum of one CO2Box sensor.
CO2BOX SENSOR MOUNTING + CONNECTING
1. Disconnect the DucoBox Reno from the mains and remove the lid of the DucoBox Reno. To do this, first remove the screw
located behind the cover plate. (Figure 11: Remove the cover plate and unscrew the lid).
2. Disconnect the motor plate by unclipping the 4 clamps. To do this, slide a flat screwdriver behind the clamp and tilt it back
slightly (approx. 5mm) so that the clamp is released from the opening in the casing (see Figure 11: open the casing and Figure
12: remove the motor plate).
3. Secure the CO2Box sensor from the outside in the desired duct port by clicking it into place on the rib closest to the motor
plate (Figure 13: Clicking the CO2Box sensor into the duct port). To do this, make a tilting movement by first tightening the
lower and then the upper clamp.
4. Pass the cable of the CO2Box sensor through the opening on the inside of the casing at the level of the corresponding duct
port. Then pass the cable of the CO2Box sensor through the relevant opening (marked with 'sensor cable') of the motor plate
according to the diagram shown below in Figure 14: four options for wiring a maximum of 1 CO2Box sensor to the circuit board.
5. Attach the motor plate to the casing. The motor plate is fixed when the 4 clamps are engaged in the casing. Make sure that the
strain relief of the power cable is pushed into the opening provided for this purpose. The power cable can be attached to the
outside of the casing by using the cable clips.
6. Connect the CO2Box sensor to the connector (CO2) on the DucoBox Reno PCB (03.A).
7. Mount the lid correctly on the unit. Make sure the notch in the lid is over the power cable opening (Figure 15: Note the notch in
the lid). Screw the lid back on and close with the cover plate.

05 Electronical installation
05.A Change settings
Most of the factory settings for the network and components will be satisfactory as they are, however, depending on the situation, it
may be desirable to change some parameters, such as the CO2setpoint. This can be done using the DUCO Network Tool. 3. This us-
er-friendly software also enables problems in the system to be pinpointed. The DUCO Network Tool is issued to every installer after
attending a free training course at the DUCO Academy4. Please refer to our website or your DUCO dealer for further information.
05.B Installer / User mode
To add, remove or replace components to the network, the system should be put in ‘Installer mode’. The LED on each component
indicates the component's active mode (see table at 05.C in the next section).
Installer mode can be activated by pressing the INST button of the DucoBox Reno (see drawing in chapter "03.A Connection & but-
tons"). When the LED on the master unit starts flashing green, 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.

05.D Pairing components
Never pair more than one system with RF components at the same time. If you do so, a component in the wrong network could be
paired, e.g. in the neighbours’ DucoBox.
PAIRING COMPONENTS ON THE DUCOBOX RENO
1. Activate ‘Installer mode’ by tapping ‘INST’ on the DucoBox. The LED will flash green rapidly.
2. 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. Repeat this step until all remaining components in the current zone have been paired. With RF components:
start with the component closest to the master. If the first pairing is unsuccessful, another component may be tried first, which
can then act as a hop for components that are unable to make an RF connection with the DucoBox.
3. Once all components have been paired, ‘Installer mode’ can be deactivated by tapping ‘INST’ on the DucoBox Reno. The LEDs
on all components will stop flashing.

06 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.
06.A Air calibration procedure for DucoBox Reno
The air calibration procedure must be carried out on a calm day (no more than wind force 2: leaves rustling, feel-
ing the wind in one’s face).
Calibrating the DucoBox Reno
1
Set all exhaust vents so they match the desired flow rate in
accordance with the table below. Proper pre-setting makes for rapid
and correct calibration.
Flow

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 lid is closed!
• Avoid air leaks in the ventilation ducts.
• Set all window ventilators to the open position

Put the DucoBox Reno into adjustment mode by pressing and together for 3 seconds until the LED next to the
INST button ( ) starts flashing. The adjustment mode is now activated for 30 minutes. There are 10 pre-programmed
calibration curves (see figure AFTER point 10 of this chapter). The LED next to flashes yellow according to a number
depending on the set control curve (from 1 to 10 times), e.g. 4 times blinking at intervals represents control curve 4 (R4).
5
Which configuration mode should I choose?
The LED next to the HIGH label lights up by default; the adjustment mode is set to
'HIGH'. Change the desired adjustment mode by pressing and briefly when
the adjustment mode is activated. The LED display next to 'HIGH' determines the
adjustment mode:
Button
Air calibration using 'HIGH'
This method is standard and has the
lowest consumption. Recommended
in the majority of homes.
Air calibration using 'LOW'
This method offers a boost mode
but may give rise to more noise
and higher consumption.
Low mode (10%) Low mode (14-33%)
Medium mode (50%) High mode (100%)
High mode (100%) Boost mode (143-333%)
LED
'HIGH' ACTIVE (green) INACTIVE (off)
The percentages in the table indicate what percentage of the flow rate configured
will be extracted.
The configuration mode chosen does not affect the operation of the AUTO mode.

Measure at the vent and adjust the DucoBox's rpm until the desired flow rate is
obtained. This can be done in two ways:
• Using the (lower) and (higher) buttons on a paired Remote control or
Room CO2/Humidity Sensor*.
• Using the ‘DOWN’ and ‘UP’ buttons on the DucoBox.
* Depending on the software version of the Remote control.
