cooled down severely.
f If the room has cooled down severely, switch the f
appliance to rapid heating stage II in order to ensure
normal appliance operation.
Quick heating stage

switched on via the temperature selector, it will heat with an
output of 2000 W at the quick fan stage.
Select the powerful quick heating stage if you need to heat up a
cold room rapidly to the selected temperature. Afterwards, set the
rocker switch back to stage "I".
Once the preselected room temperature has been reached, the
appliance switches off. The appliance then starts and stops heating
as necessary to keep the room temperature constant.

10. Troubleshooting

If the appliance does not heat, 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 heating contractor. To
facilitate and speed up your enquiry, please provide the serial
number from the type plate (000000-0000-000000).
