L1315004 Installation manual DucoBox Energy Premium (Revision K |27.09.2023 )
01 Introduction
The DucoBox Energy Premium is a mechanical ventilation unit with
heat recovery. It supplies fresh air mechanically to and extracts
contaminated air mechanically from the house by means of built in
fans. During this process, the heat is recovered from the extracted air
and transferred to the air supplied.
The DucoBox Energy Premium is a functional product and must be
installed by a qualified installer.
A mechanical ventilation unit with heat recovery consists of:
• The unit
• Ducting systems to draw in outdoor air
• Ducting systems to exhaust stale air outdoors
• Ducting systems to supply fresh preheated air indoors
• Ducting systems to extract stale indoor air to the unit
• Supply valves/window ventilators to supply preheated air to dry
rooms1.
• Extract valves/window ventilators to remove contaminated indoor air
from wet rooms2.
1. Dry rooms: living rooms, bedrooms, etc.
2. Wet rooms: kitchen, bathroom, toilet, etc.

01.B Operation
2-zone system
The DucoBox Energy Premium models with 2-zone system (types 2Z) offer the option of dividing the home into a day and night
zone. This means that ventilation will only operate in the relevant zone, which means reduced energy demand on the unit, the unit
runs quieter and increased heat transfer is possible.
Zone designations
You need to take account of zone designations when you use an integrated 2-zone sys-
tem.
Zone 1 is always the bevelled side of the DucoBox Energy Premium.
1
212
Bypass
The system includes a modulating bypass. This ensures, if necessary, that there is no heat transfer between the exhaust and
outdoor air. This means that the house cools down in a controlled and gradual manner. This function is active mainly in the
summer. The bypass opens if the indoor temperature rises above the set comfort temperature (set to 22 °C by default) and the
outdoor temperature is above 10 °C.
Frost protection
The unit features frost protection as standard in order to protect it at very low outdoor temperatures and enable it to operate
correctly.
1. Frost protection without a preheating element
The supply flow rate is slowed down gradually such that more warm air passes across the heat exchanger. This prevents the
heat exchanger from freezing up. If the imbalance is insufficient to prevent it from freezing up, then the unit will be temporarily
switched off.
2. Frost protection with a preheating element
If there is a risk of the heat exchanger freezing up, due to too low outside air temperatures, the preheating element comes
into play to raise the temperature until there is no danger of the heat exchanger freezing up. This keeps ventilation flow rates
constant.
If, in extreme cases, the preheating element is unable to heat up the outdoor air sufficiently, then a combination of the
preheating element and imbalance (as described in point 1) will be provided. If the combination is insufficient to prevent it from
freezing up, then the unit will be temporarily switched off.
Constant Flow
The unit features constant flow regulation. This ensures that the air flow rate between the supply and exhaust side remains
constant if the filters become dirty.
Passive House
The DucoBox Energy Premium 325 with heater is certified for use in a Passive House. See chapter "Passive House" on page 28
for more information.

must be connected to an earthed and fused wall socket.
Secure the unit, preferably in an enclosed space, using the correct screws and mounting bracket, to a wall or using a support frame
on a floor with sufficient load-bearing capacity.
The fan unit can only be used with the appropriate DUCO accessories and user controller(s). The installer should ensure that the
fan unit is placed at least 3m away from a chimney pipe. The unit must not be used in locations where it could be subject to direct
water spraying. Certain situations may require the use of acoustic insulation materials.
Check that the unit is complete and undamaged when you take it out of the packaging. If in doubt about this, contact DUCO / your
DUCO distribution point.
Electrical equipment should be handled with care.
• Never touch the unit with wet hands.
• Never touch the device when barefoot.
Do not use the unit in the presence of flammable or volatile substances such as alcohol, insecticides, petrol etc.
Make sure that the electrical system to which the unit is connected, complies with the stipulated conditions. Do not expose the
device to weather conditions. Do not place any objects on the unit.
Do not use the unit as an extractor for water heaters, heating systems, etc.
Ensure that the unit discharges into a single exhaust duct that is suitable and installed for the purpose and exhausts to the outside.
Ensure that the electrical circuit is not damaged.
Replace both filters in the unit every 6 months at most; this ensures that the unit is always protected against contamination and
that the air being drawn in is always healthy.
Always observe the safety instructions in the manual when installing the device. Failure to follow these safety instructions,
warnings, notes and instructions may result in damage to the DucoBox Energy Premium or personal injury and DUCO NV cannot be
held responsible for this.
Installation of the DucoBox Energy Premium should be carried out in accordance with the general and locally applicable building,
safety and installation regulations of the municipality and other authorities.
Only an approved installer should install, connect and commission the DucoBox Energy Premium as described in this manual.
Keep the manual near your unit. Maintenance instructions must be followed closely in order to avoid damage and/or wear.
It is recommended that a maintenance contract be taken out to ensure the unit is regularly inspected and cleaned. The device
must be fitted in a touch-safe manner. This means, among other things, that under normal operating conditions no-one can reach
moving or electrically live parts of the fan without intending to do so for operations such as:
• Taking off the cover.
• Taking the motor module out of the fan after removing the cover.
• Disconnecting a duct or control valve from the connection opening during normal operation.
It must not be possible to touch the fan by hand. Therefore, a ductwork should always be connected to the DucoBox Energy
Premium before commissioning. Therefore, at least 900 mm of ducting must be connected to the unit.

04.C Options power supply
For power supply, DUCO offers two options:
DESCRIPTION ARTICLE NUMBER
Power supply 230VAC-24VDC/20W + casing 0000-4763
Duco Power Adapter 230VAC-24VDC/20W 0000-4762
04.D 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.
Therefore, consider walls and concrete and metal objects. 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). Consult the RF communication information
sheet (L8000001) on www.duco.eu for more information.
DUCO RF
Power supply 230 VAC
Wiring 1,5 mm²
Frequency 868,3 MHz
Maximum distance 350 m in free field (less due to obstacles)
Maximum number of components Up to 25 wireless components in a single system
04.E Wired (cabled communication)
Wired components can be daisy-chained (= recommended). This means that a separate cable will not be required for each
component. One central power supply can be used.
The cable required is a 0.75 mm² data cable. We strongly recommend using a shielded cable to avoid interfering with data
communication.
DUCO WIRED
Power supply 24 VDC
Wiring 5 x 0.75 mm² (5 x 0.25 mm² from Tronic window ventilators)
Maximum distance up to 300 m
Maximum number of components Up to 50 wired components in a single system
04.F Modbus TCP/IP
Communication with building management systems is possible, for reading out information as well as controlling the ventilation
system. This requires the DucoBox Energy Premium to be fitted with an optional Duco Connectivity Board. Consult the Modbus
TCP/IP instructions at www.duco.eu.

05 Mounting
05.A General guidelines
The proper functioning of your DUCO ventilation system depends entirely on the choice and implementation quality of the supply
and exhaust ducts! Therefore, keep the following guidelines in mind when choosing the installation location.
Before putting the unit into operation, it must first be connected to a duct network to prevent you from being able
to touch the fan.
• Always use high-grade materials and seals in order to achieve the best airtightness. The entire system is based on proper
airtight connections and duct routing.
• The ductwork is to be installed with as few bends as possible and hence 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 supply duct (fresh outdoor air) must be far enough away from a polluted source. This could be the exhaust duct, or an outlet
duct of combustion air. Please refer to applicable local legislation (e.g. for BE: STS-P73-1 chapter 4.16.3; for NL: EN13779:2007
table A.2; for FR: DTU 68.3 P1-1-1 (6.5) + P1-
1-4 (5.1.2) etc.)
• To achieve maximum acoustic comfort,
DUCO recommends installing a silencer on
the ducts going into the house. A silencer
may also be needed in order to prevent
voices from carrying from one room to
another.
• Ducts connected with the outdoor air must
be adequately insulated in order to prevent
condensation. Any ducting in uninsulated
unheated spaces also needs to be insulated.
• Always install the extract air duct on the
house side (ETA) draining towards the unit 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.
• It is better to choose the supply of outdoor
air on the north side, to avoid drawing in too
warm air inside during the summer months.
• Take care to ensure that the air inlet is
accessible for any cleaning that may be
required. A smaller passage area can
actually have a major negative impact on
system performance.
• DUCO recommends installing a minimum
of 40 cm length of straight ducting before
deflecting the air flow on the outdoor air side
of the supply.
Also consult our "12 not-to-be-missed tips" for
an overview with the most important points of
interest.
EHA
SUP1
SUP2
ETA
ODA
64mm
0000-4376
80mm
Use thermally insulated ducts for ODA
and EHA.
Use at least 1m of flexible or rigid
silencer.
Rigid = low emission from housing
Flex = low noise from duct
Duct diameter:
^160mm to 250 m³/h / ^180mm from 250 m³/h and
over or equivalent subject to calculation (e.g. with cast-
in ducting)
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.
Hang the unit level.
Allow sufficient space for the
condensate drain.
Use silencers between
rooms to prevent voices from
carrying.
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.
Use brackets
with a rubber
inlay to reduce
transmission of
vibration.
Keep resistance down
to a minimum.
Avoid as much as
possible the use of
curves. Avoid sharp
angles. Avoid bumps
and dirt in the ducts.
Select a roof pass-through
with low resistance.
Assure an airtight connection by
using tape, clamping strips or tie-
wrap. Do not use screws. Place
a cap on any unused connection
opening.
Ensure there is sufficient distance
between ODA and EHA cf. EN 13779.

Standard siphon
(not included)
When using a standard siphon connection, a water seal
of at least 80 mm must be provided. Before start-up,
it should also be filled with water,to avoid an air leak,
prevent sewer odour in the ventilation system and obtain
a water lock.
DucoBox Energy Premium (flat) siphon
(not included)
Preferably use this flat membrane siphon from DUCO, as
it is space-saving and less likely to cause air leaks. It can
be fitted ‘dry’ and it has the advantage that it cannot dry
out in hot weather.
05.E 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 obtrusive noise and pressure drop (see table).
Make sure the total back pressure is as low as possible
(target ≤150Pa) and the air velocity in each duct is less
than 3m/s.
Integrating connectors
Based on the chosen duct diameter, connect the
appropriate connection pieces (with joint) to the ventilation unit. The 4 spigots on the ventilation unit have a diameter of ^160 (F).

05.F Vents
Preferably use DUCO vents, such as DucoVent Basic, DucoVent Comfort, DucoVent Design or DucoVent Premium. Please refer to
the technical data sheet or mounting instructions of the DUCO vents. When installing vents, it is best to observe a few rules:
• Ensure that the supply and extract vents are at least 1.5m apart so that the different airflows cannot come into contact with
each other.
• 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.
• Maximum supply flow rate per vent: 50m³/h.Startup

06 Startup
06.A Starting up DucoBox Energy Premium
The unit must not be powered up until everything has been connected correctly. This includes the air ducting
systems as well as all electrical components. Failure to connect correctly may result in destructive damage to the
DucoBox Energy Premium or serious bodily injury!
Switch on the power to the DucoBox Energy Premium (plug into power socket). When the DucoBox Energy Premium 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 ( ).
06.B Next steps
After this, you can proceed to the next steps to finish the installation:
• Pairing control components to the DucoBox Energy Premium (Electrical installation, zie pagina18).
• Air-side calibration of the DucoBox Energy Premium (zie pagina21).
• If there are no CO2and/or humidity sensors in the system, a time programme can be set (see page 24).
• Optional: changing settings. The factory settings will suffice in most cases. However, it is possible to configure settings such as
the Bypass and comfort temperature to suit the resident’s wishes (see page 25).
After this, the DucoBox Energy Premium is ready for use.
To avoid contamination of the ducts, it is recommended that the unit be operated only when there are occupants, to avoid dust from
the construction phase in the ducts and the unit.
06.C What in case of power failure?
When the DucoBox Energy Premium falls without power, it will retain all settings. When power is restored, the DucoBox Energy
Premium will restart and function again. If the DucoBox Energy Premium falls without power for longer than (approximately) 8h,
the correct time will need to be reset.

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 Energy Premium will automatically detect whether it is a 1-zone or a 2-zone system. 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. Namely:
• DucoBox Energy Premium without 2-zone system (types 1Z): all components
• DucoBox Energy Premium with 2-zone system (types 2Z): only components in
wet rooms (bathroom, toilet, kitchen, laundry...).
Briefly tap any button of all components to be paired*. The LED on the component
will start flashing green once it has been paired correctly. The number of paired
components will be shown in 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.

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 Energy Premium 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, zie pagina26).
• RESET NETWORK: this removes all paired control components from the network.
• FACTORY RESET: this resets the entire system (= DucoBox Energy Premium + paired components) to factory settings. The
calibration will be lost.
Use the Duco Network Tool or the Duco Installation 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.
