1. General information
1.1 Description of the unit
WTW-WAND-RC is a decentralized, ductless ventilation unit with heat recovery, intended for residential
buildings Also referred to us “push & pull”, WAND-mounted or single-room unit. 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 WAND.
The unit should operate continuously, and only 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.
1.2 How to use this manual
Read this manual carefully before using the product and keep it in a safe place for reference.
This manual is intended as a reference book by which qualified installers can install the WTW-WAND unit and
alloptional device as well. This device must be used according to its purpose. Make sure you have read and
understood the manual before you install and/or use the device. Please be informed that we are constantly
working on development and improvement of our products hence minor differences between this document
and your unit are possible.
1.3 Admonitions

User Manual
WTW-WAND-RC
• 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 as well as 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: -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 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/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.

The unit is supplied with an infrared remote controller (K) as standard, as well as its support base (L) which
can be WAND mounted. A magnet keeps the controller attached to the base.
The controller is equipped with an LCD display to visualise the setting to be transferred to the unit. Everytime
the button is pressed, the remote controller sends data to the unit. The acoustic signal confirms that the data
was recieved. The transmission is unidirectional, which means that the remote controller can not read data
from the unit. The IR receiver (J image pag.15) is placed on the left side of the ventilation unit: it is recom-
mended to point the controller towards the receiver when any setting needs to be transfered.
One remote controller can control more units.
NOTE!
To activate the remote controller it is necessary to insert two AAA type batteries (not sup-
plied).

Smart humidity control
When the humidity sensor detects a quick
variation of the Relative Humidity level, the
running speed automatically increases to the
next higher speed. After 10 minutes from the
last quick RH variation, the unit returns running
at the selected speed. The smart humidity
control is active if the airflow direction is set on
alternate or extract only: if speed 5 has been
selected, no speed increase happens. To disable
this functionality, press the button for 5
seconds: on the top side of the LCD display the
symbol is shown.

Antifrost
This functionality prevents frost building up on
the heat exchanger due to extremely cold air.
When it is activated, the unit runs in extract

Acoustic signal
Any time a setting is transferred from the
controller to the unit, a short acoustic signal
is emitted. This can be deactivated by pressing
the button for 7 seconds, after when a
green led flashes to indicate that the acoustic
signal is off. To reactivate the acoustic signal
repeat the same operation for 7 seconds until
the led becomes green and an acoustic signal
is emitted.

4.3 BACK UP button
In case the remote controller gets lost or the batteries are dead, the device can be controller, to a limited
extent, using the BACK UP button. You can choose speed 1 or 3 and turn off the heat recovery unit. (C image
pag.15). The airflow direction is always alternate and the operation mode (either comfort or efficiency) is the
last selected from the remote controller.

5. Synchronisation of a number of units
It is possible to synchronized up to 10 units contemporaneously, through wire (2 pole twisted pair type,
max 30m length) so to have mode and inversion time synchronized. When the unit is switched on for the
first time, the rotation direction of each unit (clockwise or anti-clockwise) is automatically established. Other
functionalities like speed, smart humidity control and boost, continue to be controlled independently on
each single unit.
Conditions and scenarios during synchronization process:
1. Each device must have been turned on independently. Turning on one device will NOT turn on the other
synchronized units.
2. The fan speed is set on each unit independently.
3. The change between Alternate / Extract / Intake modes is independent for each unit. If, for example,
only in one unit the intake mode is turned on, the other units will continue to operate in alternate mode.
4. The change of the COMFORT / EFFICIENCY modes is synchronized, i.e. a change of mode in one unit results
in a change to all units.

6. Maintenance
Maintenance can be carried out by the user as indicated in page 28.
7. 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.
