4.3.3 Operating modes
Comfort mode
As soon as the selected room temperature is reached, it is con-
stantly maintained at this selected temperature through periodic
heating. The output of the appliance must correspond at least to
the required heat demand of the room.
If several appliances are installed in a single room, the setting
at the temperature selector on each appliance can be different.
Note
To avoid excessive power consumption when windows
are open, switch the appliance off while airing.
ECO mode (night setback)
On this setting the comfort temperature set at the temperature
selector is automatically reduced by 3 °C.
Frost protection
In this position, the temperature controller switches heating on
automatically if the room temperature drops below the frost pro-
tection temperature.
Automatic
If the appliance is connected to an optional control device, you
can use this to operate it. Depending on the setting of the control
device, the appliance heats at certain times of the day in comfort,
ECO or frost protection mode.
If the appliance is not connected to a control device, the appliance
heats in comfort mode.
4.4 Limiting the temperature selector
(CNS U | CNS UE)
Using the two pins fitted to the back of the control casing, you
can fix the temperature selector at a certain setting or limit the
temperature setting range.

If a pale brownish discolouration appears on the appliance
casing, wipe it off with a damp cloth.
f
f
Clean the appliance when cold with ordinary cleaning prod-
ucts. Avoid abrasive or corrosive cleaning products.
Note
As part of regular maintenance, we recommend also
having the control components checked. The safety and
control components should be checked by a contractor
no more than ten years after commissioning.
6. What to do if...
... the appliance does not heat up:
f
f
Check the temperature set at the appliance and the MCB/fuse
in your fuse box.
The appliance has a safety temperature controller that shuts the
appliance down if it overheats. After the cause has been removed
(for example air outlet or inlet apertures covered) and the appli-
ance has cooled down for a few minutes, operation starts again.
If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your enquiry, please provide the serial
