01 Introduction
01.A Operation
The unit extracts stale air mechanically out of the home using a fan controlled on the basis of CO2, humidity or presence. Energy is
extracted from the warm extraction ventilation air combined with added outdoor air. This extraction ventilation air is supplied into
the living spaces via self-regulating or electronic grilles.
This energy is transferred to water for central heating or domestic hot water. By combining indoor and outdoor air, it can deliver up
to 2.5 kW at an outdoor temperature of -7°C and do so with high efficiency. Frost protection ensures that the unit cannot sustain
any damage.
The DucoBox Eco is a modulating heat pump which enables compressor consumption to be reduced substantially, matched to the
current heat demand in the home. As a result of this, the unit always runs at optimum efficiency, thus enabling the ideal sea-
son-based efficiency to be guaranteed.
The DucoBox Eco is a functional product and requires to be fitted by a professional Duco installer.
System make-up
The DucoBox Eco is a component, the ventilation heat pump, in a total ventilation, heating and domestic hot water concept. Apart
from the DucoBox Eco, the system consists of the following components:
Air side Water side
• Ducting systems to draw in outdoor air
• Ducting systems to exhaust mixed air outdoors
• Ducting systems to extract stale indoor air to the unit
• Inlet grilles
• Sensors
• Exhaust vents
Depending on the concept:
• DucoBox Eco Boiler Control
• Buffer tank
• ...
Zoned ventilation system
The ventilation system demand control can be maintained by using control valves in the unit. This means that there will be no heat
losses caused in the home. Moreover, the unit features 1 or 2-zone control and a day & night zone through the use of DUCO control
valves. This means that ventilation will only operate in the relevant zone, which means that the energy demand on the unit is redu-
ced and the unit runs quieter.
01.B Scope of supply
Before starting to install the unit, check to ensure it is complete and undamaged. The scope of supply of the DucoBox Eco compri-
ses the following components:
• DucoBox Eco
• Installation guide
• Hanger bracket
• Condensate drain adapter, 32 mm tube with thread
• 2 levelling feet for adjustment against a wall
• Automatic vent
• Product label
• Blanking cap for 1-zone system

• Spraying with water
Take care to ensure that the unit is kept upright at all
times in transit and while being unpacked.
The DucoBox Eco is supplied in individual packaging,
chosen so as to prevent any damage from occurring
during normal handling. Avoid shocks during trans-
port and handling.
Check that the unit and accessories are complete
and undamaged when you take them out of the
packaging. If you have any doubt about this, please
contact DUCO / your DUCO sales outlet.
Always leave the unit standing or suspended upright
first for half an hour before powering it up.
Attach the unit, in an enclosed space, using the
correct screws and mounting bracket, to a wall or
on the DucoBox Eco Mounting Plinth on a floor with
adequate load-bearing capacity. The weight of the
DucoBox Eco increases up to 95 kg in use.
The fan unit can only be used with the appropriate
DUCO accessories and user control(s).
Certain situations may require the use of acoustic
insulation materials. Take account of applicable
standards around noise requirements. (Belgium:
NBN S01-400-1)
When fitting the DucoBox Eco, take account of appli-
cable standards in respect of the distance away from
the flue pipe.
Ensure that the unit discharges into a single exhaust
duct that is suitable and installed for the purpose
and exhausts outdoors.
Keep the manual close to your unit.
Do not place any objects on the unit.
It must not be possible to touch the fan by hand.
A minimum of 900 mm of ducting must therefore
always be connected to the DucoBox Eco before it is
put into operation.
Use appropriate tools to work on the unit.
Use the unit only for applications for which it has
been designed as stated in this manual.
The ventilation unit is required to operate continuo-
usly, i.e. the DucoBox Eco must never be switched
off. (Legal requirement under NBN D50-001 Section
4.2. System C)
This unit is not intended for use by people (including
children) with reduced physical, sensory or mental
capabilities, or who lack experience or know-how,
unless they are supervised or have been given
instructions on the use of the unit by a person who is
responsible for their safety. Children must be super-
vised to ensure that they do not play with the unit.
The user is responsible for safely removing the
ventilation unit at the end of its useful life, in accor-
dance with locally applicable laws or regulations. You
can also take the unit to a collection point for used
electrical equipment.
The unit is only suitable for housing construction and
not for industrial use.
Modifications to the unit or to specifications stated in
this document are not permitted.
Always refer to the installer of your combustion
appliance to establish whether there is a risk of flue
gas ingress into the dwelling. Negative pressure in
the home can be reduced by making sure that win-
dow ventilators are always adequately open.
It is recommended that you take out a maintenance
contract to ensure the unit is regularly inspected and
cleaned.
The device must be fitted in a touch-safe man-
ner. This means, among other things, that under
normal circumstances no-one can reach moving or
electrically live parts of the fan, the cooling section
or controls without performing a conscious act to do
so, such as:
• Removing the cover using suitable tools.
• Opening the electrical control unit plus display
using the appropriate tools.
• Disconnecting a duct from the connection ope-
ning during normal operation.
• Taking the motor module out of the fan after
removing the cover.
Electrical and water installation must be carried out
by an individual who is qualified in accordance with
the applicable technical regulations by the relevant
competent authorities. Ensure that the system is in a
technically perfect condition after installation. Poor
installation can result in water leaks, electric shocks
or fire.
Electrical regulations
• Take care to ensure that the electrical supply is
a 230 V, single-phase earthed, 50/60 Hz, AC sys-
tem. The device must be connected to an earthed
and fused wall socket. Make sure that the
electrical system to which the unit is connected
complies with the stipulated conditions.
• Never touch the unit with wet hands.
• Never touch the device when barefoot.
• When handling electronics, always take measu-
res to inhibit ESD, such as wearing an earthed
wristband.
• Ensure that the electrical circuit is not damaged.
• Ensure that before work begins, the device is
isolated from the power supply by removing the
power cord from the wall socket or by switching
off the fuse. (Use a measuring instrument to
check that this is actually the case!)
• Check to ensure that cables and leads are not
damaged.
• The electronic components of the heat pump unit
may be live. In the event of a fault, contact a pro-
fessional installer and only have repairs carried
out by expert personnel.
• If the power cord is damaged, it must be replaced
by the manufacturer, after-sales support or indi-
viduals with comparable qualifications in order to
prevent any hazard.
• Do not pull on the cord to remove the plug from
the socket.
• Check that the voltage shown on the CE label
matches the local mains voltage before you
connect the unit. You will find the CE label on top
of the unit.
• Take care to ensure that all plumbing pipework
has been earthed correctly, as well as any metal
air ducting.
• The DucoBox Eco meets legal requirements
imposed on electrical equipment.
• We recommend to place the heat pump in a
separate circuit equipped with its own fuse (C
or D curve). Take also into account the section
of the electric wiring, so that it corresponds
with the current regulations regarding technical
installations.
Water regulations
• Use only mains quality tap water to connect to
the DucoBox Eco.
• Damage can occur if the water is very hard,
corrosive or contaminated with chemicals, for
example.
• Water pipes can be hot during operation. Do not
touch them with bare hands.
• Insulate all water pipes coming out of the unit
for optimum efficiency, against condensation or
against a burning hazard on contact.
• Recommended circulating water quality:
→ pH value 7.0 – 8.5
→ Hardness (°dH) 1 – 1.2
• Do not use any pipe fittings that give rise to
galvanic corrosion.
• Check the entire water system for leaks.
• Use an external expansion vessel and pressure
relief valve. There is no expansion vessel in the
DucoBox Eco.
• Use and maintain an external dirt separator for
optimum heat exchange efficiency.
• Use an external microbubble separator in your
water system.
• Fill the condensate drain before switching the
unit on.
Cooling regulations
R134a is one of the commonest ‘environmentally
friendly’ refrigerants on the market and does not
attack the ozone layer.
• All pipes are pressurised.
• Contact with this fluid can result in frostbite and
serious eye injuries.
• Depending on temperature and pressure, R134a
can form a flammable mixture with air.
• Do not discharge R134a into the open air.
• Only a qualified refrigeration technician is per-
mitted to work on the cooling system.
• At high temperatures, R134a can break down into
toxic and corrosive substance: hydrogen fluoride
and CO or CO2.

need to allow for features such as walls, concrete and metal. All slave com-
ponents (except those which are battery powered) also act as repeaters. Sig-
nals 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

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
shielded cable. This is to prevent any interference that may affect the data
communication. Any Tronic grilles will be supplied with a 5x0.25 mm² cable
which can be connected via a splicing terminal block.

05 Fitting
05.A General guidelines
The smooth running of your Duco ventilation system is totally dependent on the choice and the
quality of implementation of the duct system! Accordingly, take account of the following guideli-
nes when choosing the installation location.
The unit must be connected to a ducting network before it is put into operation.
This is to prevent you from being able to touch the fan.
• Observe all safety instructions set out in this manual.
• Always use high-grade materials and seals in order to achieve the best airtightness. The entire system is based on proper air-
tight connections and duct routing.
• The ductwork is to be installed with the smallest possible number of bends and the least resistance. The system is based on a
maximum resistance of 150Pa.
• Take care to ensure that the ducts are free from dents, long screws and extra obstructions on the inside. This is detrimental to
proper maintenance and sustainable operation.
• The outdoor air supply duct is only used to extract heat with the unit rather than drawing fresh air into the home.
• Although the DucoBox Eco is a very quiet system, it is advisable to fit silencers on the ducts coming from the home to the unit in
order to obtain maximum acoustic comfort.
• Ducts connected with the outdoor air must be adequately insulated in order to prevent condensation from forming. Any ducting
in uninsulated unheated spaces also needs to be insulated.
• Install the exhaust duct on the house side (ETA 1 and/
or 2) draining towards the unit in all cases in order to
avoid any build-up of condensation in the duct. A great
deal of moisture-laden air can be extracted during
showering or cooking.
• You are best choosing the outdoor air supply (ODA) on
the south-facing side so as to draw as much heat as
possible into the unit.
• Use the blanking cap supplied (including insulation) to
seal off the unused connection opening.
• Take care to ensure that the air inlet is accessible
for any cleaning that may be required. A smaller
cross-sectional area bore can actually have a major
detrimental impact on system performance.
• Duco advises you to fit a minimum of 40cm length of
straight ducting before diverting the air flow on the
intake side of the supply.

0000-4376
Use at least 1m of flexible or rigid
silencer.
Rigid = low emission from housing
Flex = low noise from duct
12
Choose a double-walled insulated roof
vent with low resistance.
9
Provide a drip moulding if the outlet
(EHA) is through the wall.
3
Secure linked ducts airtight using
tape, hose clamps, tie-wraps or use a
sleeve with rubber. Do not use screws.
Place a cap on any unused connection
opening.
4
Use rigid thermally insulated ducting for ODA and EHA. A
diameter of200mm is recommended for an acoustically
sensitive / long installation. Never use flexible
connections. Avoid unnecessary bends in this duct.
2
Ensure there is sufficient distance between
ODA and EHA for optimum efficiency.
1Keep resistance down to a minimum.
Avoid as much as possible the use
of curves. Avoid sharp angles. Avoid
bumps and dirt in the ducts.
10
Use brackets
with a rubber
inlay to reduce
transmission of
vibration.
11
Allow sufficient space for the
condensate drain.
14
Hang the unit level.
6
Use flexible hose with a shut-off valve
at each water connection.
5
Locate the power socket directly
above the unit for reasons of splash-
proofing.
13
ETA duct diameter:
Follow the guidelines for maximum airflows per
duct diameter, based on noise generation and
pressure drop:

Take care to ensure that total back pressure
is as low as possible (target ≤ 150Pa) and air
velocity in each duct is < 3m/s and <1.5m/s in
branch take-offs.
8Use silencers between rooms to
prevent voices from carrying.
15
For wall mounting: wall with minimum mass
density of200kg/m². Plaster blocks or
metal struts are not adequate!
Use a mounting plinth if the wall is not
sufficient.

The correct operation of your Duco ventilation system is entirely dependent
on the choice and build quality of the supply and exhaust ducts!
15 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!
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.

05.E Fitting condensate drain
The DucoBox Eco must always be fitted with a condensate drain at the bottom. The unit is supplied with a standard 32mm drain
with a threaded end. There is an extra 32mm diameter by 20cm connecting pipe in the packaging. Condensate must be drained
frost-free and with a slight fall. The condensate hose must not have any sharp bends.
Screw the condensate drain onto the unit. There are two recommended options:
• A traditional water seal type S-trap
• A flat trap
Standard trap
(not included in the supply)
When using a standard trap connection, a water seal
of at least 80mm must be provided. It also requires
to be filled with water before start-up. This is to
prevent an air leak from occurring, preventing drain
smells in the ventilation and to obtain a water seal.

SUP RET
Fit an expansion vessel on the cold side of the water section in order to accommodate rising pressure in the system. Its size will
depend on the water capacity of the system.
05.H Connecting air ducts
Choosing air ducts
Flow rate and maximum air velocity are defining factors in
choosing the right ducting in order to avoid generating any extra
intrusive noise and pressure drop.
ETA duct diameter
Follow the guidelines for maximum airflows per duct diameter,
based on noise generation and pressure drop:
Ø 100 Ø 125 Ø 150 Ø 180
0-30
m³/h
30-150
m³/h
150-250
m³/h
250-400
m³/h
Take care to ensure that total back pressure is as low as possi-
ble (target ≤ 150Pa) and air velocity in each duct is < 3m/s and
<1.5m/s in branch take-offs.
ODA and EHA duct diameter
Use rigid thermally insulated ducting for ODA and EHA. A diame-
ter of200mm is recommended for an acoustically sensitive / long
installation. Never use flexible connections. Avoid unnecessary
bends in this duct.

05.I Vents
You should preferably use Duco vents, DucoVent Basic or DucoVent Design. See the technical data sheet or fitting instructions for
the DucoVent Basic or Design for details. It is best to bear a few rules in mind when fitting vents:
• It is preferable not to fit a vent right next to a wall in order to prevent soiling.
• In order to cut down resistance, we recommend using 125mm dia. vents only.
• Maximum exhaust flow rate per vent: 75m³/h.

06 Commissioning
DucoBox Eco start-up
The unit must not be powered up until everything has been connected correctly and the transit foam blocks in
the unit have been removed. This includes the air ducting systems as well as all electrical components. Failure to
connect correctly can result in irreparable damage to the DucoBox Eco or to serious physical injury!
Switch on the power to the DucoBox Eco (plug into power socket). When the DucoBox Eco starts up for the first time, you will be
asked to enter a few basic settings. Navigate using the arrow keys ( and ) and confirm using enter ( ).
Next steps
After these steps, you can proceed with the following steps in order to complete the installation:
• Set system type in accordance with the chosen concept via SETTINGS → SYSTEM TYPE.
• Pairing control components to the DucoBox Eco.
• DucoBox Eco air-side calibration.
• DucoBox Eco water side calibration.
• Recommended: Settings for CH and DHW.
The DucoBox Eco will be ready for use after that.
IMPORTANT! In order to avoid contamination in ductwork and in the unit, it is advisable not to put the unit into
operation until the home is occupied. This is to prevent dust from the building phase getting into the ductwork and
the unit.
What happens in a power cut?
If the power supply to the DucoBox Eco fails, it will retain all its settings. Once power has been restored, the DucoBox Eco will start
up again and run. The correct time will need to be set again if the DucoBox Eco is without power for more than (around) 8hours.

07 Electrical system
07.A Pairing components
ZONE 1 ZONE 2
Zone designations
You need to take account of zone designations if you are utilising an integrated 2-zone
system.
Pairing control components with the DucoBox Eco
Ensure that the control valves have been fitted in the unit and connected before starting the pairing procedure.
1
Activate advanced mode:
• Scroll down to ADVANCED and press enter.
• Enter the installer’s code 9876 and press enter.
2Go to the INSTALLATION menu.
3Start the WIZARD.
The DucoBox Eco will automatically detect whether it is a 1-zone or a 2-zone system. Control valves are paired automatically as
soon as the wizard is launched. The system now enables control components to be paired with the entire system (step4), zone1
(step5) or zone2 (step6).
4
Pair the desired control components with the entire system. I.e.:
• DucoBox Eco with 1 zone: All components.
• DucoBox Eco with 2 zones: Any components that are applicable to the complete
system, such as a DucoBox Eco Boiler Control, a User controller for both zones
(= master control) and a Duco Weather Station.
Short-tap on a random key on all components to be paired*. The LED on the com-
ponent will start flashing green once it has been paired correctly. The number of
paired components will be shown on the display menu. Confirm by pressing enter(
) once all the desired components have been paired.
*Please refer to the control component manual for comprehensive instructions.
5
FOR A 2-ZONE SYSTEM ONLY
Pair the desired control components with zone1. This could be the daytime zone
(living room, office, etc.) Then confirm by pressing enter( ).
6
FOR A 2-ZONE SYSTEM ONLY
Pair the desired control components with zone2. This could be the night-time
zone (bedrooms). Then confirm by pressing enter( ).
All components have now been paired. This wizard can be run again if additional control components need to be paired at a later
stage. All previously paired components will be retained in the network.

07.C Tips
The network can be wiped or a full reset of the DucoBox Eco can be carried out in the event of any problems. To do this, refer to the
following functions under the INSTALLATION menu (visible only after activating advanced mode, see page<OL>).
• RESET NETWORK: this removes all paired control components from the network.
• FACTORY RESET: this resets the entire system (= DucoBox Eco + paired components) to factory settings. The calibration will be
lost.
Use the Duco Network Tool or the Duco Ventilation App to read out information from components.
Never pair more than one system with RF components at the same time. This could result in components on the wrong system
being paired or in components failing to respond.

08 Air-side calibration
Calibrating the DucoBox Eco can be split into various steps:
1. Pre-setting exhaust vents
2. Calibrating flow rates
The system needs to be configured for it to work correctly.
This will ensure its operation is as quiet as possible and energy-efficient.
08.A Pre-setting vents
The exhaust vents are installed in a duct for moisture-laden/stale air extraction. In order to calibrate the air extraction correctly,
these vents must be set depending on the situation in accordance with the table below.
SITUATION 1:
One vent per zone
SITUATION 2:
Multiple vents per zone
with equal flow rates
SITUATION 3:
Multiple vents per valve with different flowrates
Set all vents to the fully
open position, regardless of
the desired flow rate. When
using DucoVent Design
exhaust vents, leave the ou-
ter ring in place for acoustic
effect.
Set all vents to the fully
open position, regardless of
the desired flow rate. With
DucoVent Design vents, turn
the cone on the trim plate to
the fully open position.
Set the vents so they match the desired flow rate in accordance
with the table.
