Your appliance is a central heating radiator with a built-in forced convection
function. When this function is activated, this quiet, compact and easy-to-use
appliance provides additional airflow to maximise heat output.
Your radiator is equipped with a number of three-speed fans to boost heat
output. The control panel is used to operate the fans only. It does not control
the independent water circuit within the radiator; this is managed by the
water supply device.
The radiator has two operating modes: Heat Mode, for which a low-tem-
perature water supply can be used, or Refresh Mode, which requires a
source of cold water. In this case, you must ensure that your cold water
supply is at a sufficient temperature to avoid water condensation on the
surface of the radiator (see section 2.3).

5General&Warning
This appliance is not intended for use by persons (including children)
with impaired physical, sensory or mental capacities, or by persons lacking
in experience or knowledge, unless they are supervised by, or have received
prior instruction in using the appliance from, a person responsible for
their safety. Children must be supervised to ensure that they do not play
with the appliance.
Radiators must be used for the purpose for which they are intended and
not as a table, chair, toy, ladder, etc. and as specified in the user and service
instructions supplied with the appliance.
Caution: To avoid overheating,
do not cover the heating appliance.
Caution: Do not sit on the heating
appliance.
Protect the radiator from splashing
water and ensure that small objects
do not fall inside it. This can disrupt or
even damage the fans.
Warning

1.1 Positioning the appliance
To get the most out of your appliance and enjoy the highest standards of
comfort, we recommend that you install the appliance near places of high
heat loss (windows, doors, etc.) wherever possible. Use mounting screws
suitable for your wall.
Important: this radiator must be installed with the fan control panel
positioned topside.
Ensure that the bottom of the radiator is positioned at least 10 cm from
the floor.

7Installing your appliance
1.2 Connecting the appliance
The technical specifications of your appliance are shown on the nameplate,
which is located on the side of the appliance towards the bottom. Please take
note of these before installing the appliance.
When connecting the appliance to the mains, you must ensure that:
voltage and power are as specified on the nameplate
standard colour coding is used
– brown: live
– blue or grey: neutral
– green/yellow: earth (only for a Class1 product)
Note: the flexible cable supplied with the appliance is designed to be
connected to the mains via a plug or a junction box (according to local
standards).
1.3 Radiator installation restrictions
This appliance must be installed in accordance with applicable standards
and good practice in the country concerned.
Important: the radiator must not be exposed to intense or prolonged
ambient humidity (from a shower, swimming pool, etc.).
IP: level of protection against ingress of
water

2.1 The radiator functions
The built-in control panel (see opposite) has the following functions:
Turn the forced convection function ON/OFF. Press the ON/OFF button (2)
to enable or disable the fans. The green LED (1) is illuminated when the fans
are switched on.
Select fan speed (LEDs, 4). Press the button (3) repeatedly to select:
Level 1: low speed (the left-hand LED lights up)
Level 2: medium speed (the middle LED lights up)
Level 3: high speed (the right-hand LED lights up). The fans will start at
high speed (boost) and revert to level 1 automatically after one hour.
Note: each time the required room temperature is reached, your water
supply (boiler or heat pump) will stop supplying hot/cold water to your
appliance.
To save energy, the sensors in your appliance will detect this and switch
the fans off automatically, whatever fan speed you have selected.
The LED corresponding to the selected speed will remain ON even if the fans
are OFF (see Appendix for more information about fan operation logic.).
2. Using your appliance
GB

9Using your appliance
Filter alarm
The red LED (5) will light up periodically to remind you to clean the airflow
filter at the bottom of the appliance (see section 3.2).
Sensor alarm
The same red LED (5) will blink in the event of a sensor fault. If so, further
action is required: contact your installer or dealer (see section 4).
Lights OFF mode
For your convenience, particularly where the appliance is installed in a
bedroom, all LED warning lights will go out automatically after 10 minutes
with no intervention required on your part.
This mode affects the LEDs only and has no impact on radiator or fan
operation. Press any button to exit this mode and restore normal LED
functioning.

Automatic Heat/Refresh Mode selection
A sensor inside your radiator monitors the temperature of the hot/cold water
supply. Another sensor measures the ambient temperature in your room.
Heat Mode is selected automatically if the water temperature rises above
the minimum Heat Mode temperature:
≥25ºC
Refresh Mode is selected automatically if the water temperature drops
below the maximum Refresh Mode temperature:
≤21ºC
Note: no action by the user is required to switch between these 2 modes:
Note: in all cases, a minimum gap of 2ºC between water temperature
inside your appliance and ambient temperature in your room is required for
fan operation.

11Using your appliance
2.2 Recommendations for Heat Mode
Maximum water temperature in your appliance
To ensure optimum service life of the components of your appliance, the
temperature of your water supply should be limited to a maximum of 75ºC.
Thermostatic valve (optional, not included)
In heating-only installation, it is possible to add a thermostatic valve to
control the flow of water and thereby the ambient temperature in your room.
2.3 Recommendations for Refresh Mode
Minimum water temperature in your appliance
Condensation may form if the temperature of the cold water used with
your appliance is too low. Be aware that your appliance is not equipped
with any condensation recovery gutter or similar.
Depending on the temperature and pressure in your room, water conden-
sation may develop, and possibly cause corrosion of your radiator and
damage to its built-in fans.
A water supply device with dew point management capability (such as
a Zehnder ComfoBox) will automatically regulate water temperature inside
your appliance with reference to ambient temperature to allow optimum
functioning.
Thermostatic valve
A thermostatic valve must not be used when the appliance is installed to
provide both heating and Refreshing.
≤75ºC

12 Taking care of your appliance
3.1 Standard maintenance operations
Before carrying out any maintenance operation on your appliance, ensure
that it is switched off. High-quality materials and surface treatment protect
your appliance against corrosion and impacts.
To maximise the service life of your appliance, we recommend you take
the following precautions:
Never use abrasive or corrosive products on the outer surfaces
of the appliance; use tepid soapy water.
Use a dry cloth, without solvent, to clean the forced convection
control panel.
3.2 Cleaning the airflow filter
The alarm LED (5) lights up to indicate that you need to clean the filter at
the bottom of your appliance, which will become clogged with dust over time.
You can use a vacuum cleaner with the filter still in place, or remove the
filter from its housing completely by pulling the filter locks forwards as shown
above (steps 1 to 3). The filter may be washed with water, but to avoid
damage we highly recommend that you do not put it in the dishwasher.
After cleaning, replace the filter by performing steps1 to 3 in reverse order
and fasten the locks. Press the ON/OFF button (2) for 4 seconds to deactivate
the alarm LED (5) (step 4).

13In case of fault
If the fans stop working, check that your appliance is properly connected
to an appropriate power supply (see section1.2).
The alarm LED (5) lights up when a fault is detected and goes out when
the fault is cleared (see section 2.1). If the LED remains on, further action is
required: contact your installer or dealer.
Note: if the power cable is damaged, for safety reasons it must be replaced
by the manufacturer, the manufacturer’s after-sales service department or a
similarly qualified person.
