IMPORTANT
This appliance is not intended for use by persons (including children) with reduced
physical sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
1.0 Introduction
A continuous running, low energy, ultra-quiet, alternate flow supply and extract fan with
heat retention for use in habitable areas such as living rooms, bedrooms, dining rooms,
basements and hallways.
The unit provides ventilation and reduces indoor air pollutants and humidity levels. The
unit is ideal for tackling problems associated with condensation dampness such as mould
growth.
It is recommended that two units are installed in pair: when one unit is pulling, the other
is pushing.
Pair of units can be installed in the same room or in different rooms (i.e. living room and
bedroom). The unit is suitable for installation on an outside wall.
The unit should operate continuously, and only be stopped for maintenance or service.
When heat exchange is not useful (for example in mid-seasons when indoor and outdoor
temperatures are similar), or when heat exchange is not recommended (for example with
the option “summer free cooling”), it is recommended to set the unit in “extract-only” or
“intake-only” mode and NOT to switch it off.

2.0 Safety
The following information must be read carefully to ensure safe installation and
operation of the unit.
2.1 General Safety
✓The device should not be used for applications other than those specified in this
manual.
✓After removing the product from its packaging, verify its condition. In case of
doubt, contact a qualified technician. Do not leave packaging within the reach of
small children or people with disabilities.
✓Do not touch the appliance with wet or damp hands/feet.
✓This appliance can be used by children aged 8 years old and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of
the appliance in a safe way and understand the hazards involved. Children should
not play with the appliance. Cleaning and user maintenance should not be
performed by children without supervision.
✓Do not use the product in the presence of flammable vapours, such as alcohol,
insecticides, gasoline, etc.
✓If any abnormalities in operation are detected, disconnect the device from the
mains supply and contact a qualified technician immediately. Use only original
spare parts for repairs.
✓The electrical system to which the device is connected must comply with
regulations.
✓Before connecting the product to the power supply or the power outlet, ensure
that:
❖the data plate (voltage and frequency) corresponds to those of the
electrical mains
❖the electrical power supply/socket is adequate for maximum device power.
If not, contact a qualified technician.
✓The device should not be used as an activator for water heaters, stoves, etc., nor
should it discharge into hot air/fume vent ducts deriving from any type of
combustion unit. It must expel air outside via its own duct.
✓Operating temperature: -20°C up to +50°C.
✓The device is designed to extract clean air only, i.e. without grease, soot, chemical
or corrosive agents, or flammable or explosive mixtures.
✓Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
✓Do not immerse the device or its parts in water or other liquids.
✓Turn off the main switch whenever a malfunction is detected or when cleaning.
✓For installation an omni polar switch should be incorporated in the fixed
wiring, in accordance with the wiring regulations, to provide a full

5/19
disconnection under overvoltage category III conditions (contact opening
distance equal to or greater than 3mm).
✓If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons to avoid a hazard.
✓Do not obstruct the fan or exhaust grille to ensure optimum air passage.
✓Ensure adequate air return/discharge into/from the room in compliance with
existing regulations in order to ensure proper device operation.
✓If the environment in which the product is installed also houses a fuel-
operating device (water heater, methane stove etc., that is not a “sealed
chamber” type), it is essential to ensure adequate air intake, to ensure good
combustion and proper equipment operation.
✓Install the product so that the impeller is not accessible from the air outlet side
as verified by contact with the Test Finger (test probe “B” of the norm EN61032)
in compliance with the current safety regulations.
2.2 Responsibility of the Installer
✓Correct Installation, balancing and commissioning of the unit.
✓Compliance to requirements and local additional rules.
✓Explanation of the ventilation system to the user.
✓Warning for the user, to check or replace the air filters on time.
2.3 Responsibility of the Occupant
✓To ensure maintenance of the ventilation unit on a regular basis. Filters should be
checked, cleaned or replace every 6 months. Details can be found on page 15
(maintenance).
✓To ensure that the fan is operating. The aircycle ONE ventilation units are designed
to operate 24/7.

4.0 Operation
In both versions, the unit extracts air out for 70 seconds, then it supplies air in for the
same time. When heated air is pulled (extracted) from inside the room, it warms up the
heat exchanger; when the cold air is pushed (supplied) in the room, it gets preheated,
recovering most of thermal energy which would be otherwise lost in the ventilation
process.
The unit runs at the speed selected by activating the switches “S1”, “S2” and “S3” of the Air
Controller (accessory fig. 57). The same functionality can be achieved with Air Controller
or with 3 switches.
S3 switch activates the “Free cooling“ (Bypass) mode, which stops alternate flow and
keeps the fan in “extract-only” or “intake-only” mode, to avoid the heat exchange when
necessary. To set the “extract-only” mode or “intake-only”, place the integral jumpers as
per fig. 20A-20B. The front cover LED indicates when the Free cooling mode is on.
An automatic “Boost”mode can be achieved through a dedicated switch or room sensors
like humidity sensor, CO2 sensor, PIR sensor, connecting such switch in parallel to the S2
switch.
Wiring diagram of one unit: fig. 18A.
Wiring diagram with ambient sensors: fig.18B-18C.
Wiring diagram of two or more units: fig. 18D.
WARNING:
Ensure that the electric wiring to L and N is done correctly; an incorrect connection will
lead to malfunction or permanent damage of the fan.
4.1 Synchronisation
When the units are installed in pair, they must be synchronised so that when one unit is
extracting, the other is supplying, and viceversa (fig. 18E-18F-18G). This is achieved by
setting the dedicated jumper (fig. 20A-20B).
RESET OF THE SYNCHRONISATION
OPTION 1: If two or more units are connected under the same main switch, to reset the
synchronisation, the main switch must be switched first OFF and then ON to reactivate
(fig. 31).

9/19
OPTION 2: If two or more units are not connected under the same main switch, to reset
the synchronisation, press at the same time the black pin of each unit (fig. 33) for at least
3 seconds.
If two or more units are controlled by means of the same controller (Air Controller or
similar), they always operate in a synchronised way.Wiring diagram as per fig. 18D
4.2 Jumper positions
Intergal jumper set in position A (fig. 20A) means “extract-only” mode. Intergal jumper set
in position B (fig. 20B) means “intake-only” mode.
The jumper position defines both the air-flow direction when the unit is activated for the
first time (for the synchronisation) and the air-flow direction of the free- cooling mode.
4.3 Disposal and recycling
Information on disposal of units at the end of life.
This product complies with EU Directive 2002/96/EC.
The symbol of the crossed-out dustbin indicates that this product must be collected
separately from other waste at the end of its life. The user must, therefore, dispose of the
product in question at suitable electronic and electro-technical waste disposal collection
centres, or else send the product back to the retailer when purchasing a new, equivalent
type device.
Separate collection of decommissioned equipment for recycling, treatment and
environmentally compatible disposal helps to prevent negative effects on the
environment and on health and promotes the recycling of the materials that make up the
equipment.
Improper disposal of the product by the user may result in administrative
sanctions as provided by law.
