This fan heater features a presence sensor and an automatic power management function.
The presence sensor allows a reduced energy consumption, lowering automatically the ambient temperature when no
presence is detected in the room for at least 10 minutes. Once someone is detected, Windy comes automatically back
to the set comfort temperature. The automatic electronic power selection, instead, manages the consumption through
an accurate and comfortable regulation keeping constant the selected temperature - according to what has previously
been set on the electronic thermostat.

GB
The product can be used choosing between 4 different operating modes:
- ANTI-FREEZE
- PROGRAMMED
- AUTOMATIC
- BASIC
Anti-freeze mode
The thermostat is set to keep 7 ± 3 ° C. The function is activated manually or automatically when no presence in the
room is detected for at least 36 hours. In this case, as soon as a presence is detected again, the product will automa-
tically set the automatic mode.
Programmed mode
The product can be programmed by selecting, for each day of the week, which of the 5 preset proles you want to use.
During all the operating time in programmed mode, the presence sensor is deactivated so that the product can correctly
follow the temperature prole set by the user.
In Programmed mode there is also a special function - which can be activated at the user's choice - allowing the detec-
tion of the eventual opening of a window and switching to the Anti-freeze mode to minimize energy waste.
Automatic Mode
The product is set to work at a comfort temperature whenever someone is detected in the room. Should no one be
detected in the room for at least TEN minutes, the heater will automatically set the Eco mode (3,5°C less than the set
Comfort temperature). Should no one be detected in the room for more than 36 hours, the heater will automatically set
the Anti-freeze mode (7°C). In case someone should be detected again for at least 2 minutes, the product will automa-
tically increase the temperature to the comfort level.
In automatic mode is also available a special feature, which is activated at user’s choice, which allows to detect the
possible opening of a window and to switch to the Anti-freeze mode to minimize energy waste.
Basic Mode
The product works in Comfort mode. The presence detection is disabled and doesn't affect the set temperature as in
Automatic mode.
In Automatic mode is also available a special feature, which is activated at user’s choice, which allows to detect the
possible opening of a window and to switch to Anti-freeze mode to minimize energy waste.
6. using the Fan heater
MAIN ON/OFF SWITCH
(placed on the left side of the product)
The power supply of the product is controlled by an electromechanical ON/OFF switch. Switching off the fan heater will
cut off the power to the electronic board causing - after 30 minutes of power supply absence - the loss of every stored
information. We recommend to use this switch only when you are not using the product for long periods. Instead, it is
possible to use the on/stand-by key for any short-term interruption, so that no stored setting will get lost.
At rst use of the product or in case of over 30 minutes power loss, when the product turns on the display shows 00:00
and begins counting the time starting from this value.
Should no adjustment be made within 15min after power up, the product will automatically switch to Anti-
freeze mode with the lighting up of the corresponding LED light.

SELECTION BUTTONS
Selection buttons are used within the menus to display and/or set the several customizable parameters as shown in
the various sections of this manual.
You can check the set Comfort temperature at any time by pressing a single time the or key. A further pression
will modify the set temperature.
Note: The temperature measured by the inner sensor of the product is representative of the ambient temperature
nearby it and it may differ from the temperature measured using other instruments in other areas of the room. That
difference may depend on many factors including, for example:
- the installation position: some areas of the room may be affected by drafts or hot air sacs that modify the sensor
measurement;
- an external wall xation: it may imply a temperature measurement lower than the real room temperature;
- an excessive towels load on the support bar may obstruct the airow. As a result the sensor may measure a tempe-
rature higher than the real room temperature;
- unstable conditions: any evaluation must be done in stable working conditions. For this purpose Comfort temperature
should be changed only 60min after a previous change. In fact, it is not possible to evaluate if the room temperatu-
re is correctly maintained by the product when the Comfort temperature gets repeatedly changed in a short time.
If the difference between set temperature and room temperature is detected in stable working conditions, measure the
difference and then increase or decrease the comfort temperature on the product of the exact measured difference
value.
OK BUTTON
The OK button is used in the various menus to conrm the chosen settings.
BOOST BUTTON
The Boost button allows to activate the timed operation for 15 minutes at maximum power without the thermostat
control. During this operation the display shows alternately the word "BooS" and the remaining time. At the end of this
forced operation, the fan heater returns to the previous operating mode.
7. troubleshooting
• In the event of overheating, the safety device on the appliance automatically disabled the heating elements and
motor. In this case:
-Turn off the fan heater and allow it to cool down for about 15/20 minutes.
- Make sure the dust lter is not totally obstructed and clean if necessary. Remember to put it back again
afterwards.
- Eliminate any other possible reasons for overheating (e.g.: obstructions in front of the air inlet/outlet grilles,
build-ups of dirt).
-Turn on the fan heater again and check its correct functioning.
• If the touch control commands are blocked or don't answer properly to digital pressure, turn off the heater for at
least 30sec using the electromechanic switch on the left side of the heater. Then turn on the heater using the
same switch.
