2.0 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 from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or in
struction concerning use of the appliance in a safe way and understand the hazards involved. Children shall
not play with the appliance. Cleaning and user maintenance shall not be made 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 original spare parts only 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) correspond 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
special duct.
Operating temperature: 0°C up to +40°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 o the main switch whenever a malfunction is detected or when cleaning.
For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring
regulations, to provide a full 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 in order to avoid a hazard.
Do not obstruct the fan or exhaust grille to ensure optimum air passage.
Ensure adequate air return into 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.
Attention: do not mount the product on the ceiling without this kit.

Motor mounted on high quality ball bearings.
Selectable minimum speed for continuous running and intermediate speed.
Option to boost from minimun speed through LS connection.
Selection of the installation type (through wall or in-room).
Selection of smart humidity control and intelligent run-on timer.
Selection of constant volume mode.
Suitable for continuous running.
The fan is double insulated: no earth connection is required.
IPX4 wall installation; IPX2 ceiling installation.

3.0 Operation
Upon power-up, the unit runs at the minimum continuous speed.
If humidistat or timer is activated, the unit runs at the intermediate speed.
If the external switch is activated, the unit runs at the maximum speed.
After the external switch is o, the unit continues to run at the intermediate speed for a period of time, then it returns
to the selected minimum speed (or to the intermediate speed in case humidistat or run-on timer operation is on).
The functionalities can be set/enabled through the Dip Switches A and B on
the electronic circuit (with disconnected from the main supply unit).

3.1 MINIMUM CONTINUOUS SPEED
Upon power-up, the unit runs at the minimum continuous speed settable from 0 to 58m3/h (i.e. from 0 to 16l/s)
by means of the switches as per table Dip Switch A.
3.2 INTERMEDIATE SPEED
The unit runs automatically at the intermediate speed settable from 29 to 72m3/h (i.e. from 8 to 20l/s) by means of the
switches as per table Dip Switch A.
The intermediate speed can be activated when either of the below conditions have been met:
- the humidistat has been activated;
- the run-on timer has been activated.
3.3 MAXIMUM SPEED
The maximum speed fixed, at 90m3/h (i.e. 25l/s) in through-wall or 72m3/h (i.e. 20l/s) in in-room installation, can be
activated through external switch, remote ambient sensor or light switch.
3.4 INSTALLATION TYPE
Based on the selected installation type, the unit scales its speed (minimum, intermediate and maximum) to obtain the
selected air flow rates.
- Through-wall installation: unit is typically mounted on an external wall or window and discharge direct to the outside.
- In-room installation: unit is typically mounted on the ceiling or internal wall which are ducted to the outside.
NOTE: the unit runs at a higher speed when In-room installation is selected.
The installation type can be selected by means of the switches as per table Dip Switch A.

3.5 CONSTANT FLOW OPERATION
When the constant flow operation in enabled, the unit speeds up or slows down depending on
the variations of the resistances caused by long length ducting or external windy conditions.
The constant flow operation can be enabled/ disabled by means of switch 1 of Dip Switch B.

3.6 HUMIDISTAT
The unit is equipped with a humidity sensor that operates in AUTO mode, i.e. the humidistat,
which records the humidity levels, triggers if there is a steep variation of the humidity and if
humidity level is over 65%. If the humidistat is activated, the unit runs at the intermediate
speed and continues to run for a fixed time of 5 minutes after the umidity level stabilizes.
The humidistat can be enabled/ disabled by means of switch 2 of Dip Switch B.
3.7 RUN-ON TIMER
The unit is equipped with a run-on timer. When the external switch is turned o, the unit
continues to run at the intermediate speed for the a period of time defined as follows:
- if the external switch is activated for less than 3 minutes, the unit does not run-on;
- if the external switch is activated for between 3 and 10 minutes, the unit runs on for
5 minutes;
- if the external switch is activated for between 10 and 20 minutes, the unit runs on for
10 minutes;
- if the external switch is activated for over 20 minutes, the unit runs on for 15 minutes.
When the time is expired, the unit returns to the minimum continuous speed.
The run-on Timer can be enabled/disabled by means of switch 3 of Dip Switch B.

8.0 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 eects on the environment and on health and promotes the recycling of the mate-
rials that make up the equipment.
Improper disposal of the product by the user may result in administrative sanctions as provided by law.
