• This convector has a double water protection level: IPX0 when
used as portable and IPX4 when wall-mounted. Respect the re-
gulations of the country concerned about its use in different en-
vironments. It can therefore be used in bathrooms or other areas
subject to humidity AS LONG AS IT IS NOT INSTALLED WITHIN
THE PERIMETER OF BATH TUBS OR SHOWERS. This means
that it cannot be installed in the areas marked as VOLUME 1 in

• The convector can also be used as a portable product by purchasing the wheels supplied separately.
• To x the wheels:
- check the correct orientation as shown in gure 7;
- x each of the 2 supports with the wheels using the screws provided as shown in gure 8. The screws can
be xed by hand and do not require any tool.

5. turning on and oFF
The product is powered by an electromechanical on / off button. Switching off the product pressing this button causes
the power supply to the electronic board to be interrupted and the current time and day to be canceled. We recommend
using it only if you do not use the product for a long time and instead use the on / stand-by button on the control panel
in the event of a short operating interruption of the device. This way you will not lose the adjustment settings previously
entered.
When switched on, the convector activates the last mode used before switching off or power failure. The time is reset
at 12:00 and the day of the week on Monday.
ON - OFF
Use the Power / Stand-by button to turn the convector on and off without losing the stored time.

7. sPecial Functions
By pressing button it is possible to select one of the following 3 special functions:
RESET function
By activating this function all the settings are restored to the initial facto-
ry value. The comfort temperature is set to 19.0 ° C, the preset program
is the one described in the appropriate section and the open window
detection function is deactivated.
5"
To RESET press the button for at least 5 seconds.
The convector is automatically set in Comfort mode.
OPEN WINDOW DETECTION function
This function allows to identify the opening of a window and to automa-
tically set the Antifreeze operation mode.
If a sharp reduction of the ambient temperature is detected during the
normal operation of the product, the antifreeze mode is automatically
activated to reduce energy wastes. The window symbol and the anti-
freeze symbol ash to indicate that the function is activated.
The restoration of normal operation is not automatic but is obtained by
pressing any of the 5 buttons of the product.
The correct functioning of this function may depend on the po-
sitioning of the product in the room, the presence of drafts, the
external temperature and the window opening time.
Activate the function by pressing the button.
The window symbol lights up on the display.
Deactivate the function by pressing the button.
The window symbol turns off on the display.

24
LOCK function

are locked.
5" Deactivate the function by pressing the and
buttons simultaneously for at least 5 seconds.
The key symbol turns off, the buttons work again.
8. teMPerature control
The electronic temperature control is based on the value that the user assigns to the COMFORT temperature.
The temperature values for the Comfort-1, Comfort-2, Eco and Antifreeze modes are automatically calculated and can
not be directly modied by the user. The reference temperature is always indicated on the display together with the
symbol representing the selected operating mode.
NOTE: The temperature measured by the sensor inside the product always indicates the ambient temperature in the
immediate vicinity of the product and may differ from the temperature measured with other instruments in other areas
of the room. This difference may depend on various factors, such as:
- The installation position: some areas of the room may be affected by currents or warm air pockets that can change
the sensor measurement;
- The installation on an external perimeter wall, which is normally colder than internal walls, may result in a lower tem-
perature measurement than the actual room temperature;
- Unstable conditions: each evaluation must be made under stable operating conditions. For this reason the Comfort
temperature should not be changed before 60 minutes have elapsed since the previous modication. In fact, it is not
possible to assess whether the room temperature is correctly maintained by the product if the temperature level is
continuously modied in a short period of time.
If the difference between the set temperature and the ambient temperature is detected in stability conditions, calculate
this difference and then increase or decrease the comfort temperature level on the product of the exact calculated
difference value.
