Starting heating

f Use the rocker switch to select one of the following operating
modes:
- Standard operation
- Operation with the time switch
Standard operation
The temperature is infinitely adjustable. The appliance switches
off as soon as the selected room temperature has been reached.
f Turn the temperature selector clockwise to the required
setting.
Operation with the time switch
The 24-hour time switch has 96 time segments. Every hour is di-
vided into 4 time segments of 15 minutes. The time switch has to
be reset when commissioning the appliance and after any power
interruption. To do this, turn the time switch clockwise until the
marker arrow points to the current time.
To select the required heating time, proceed as follows:
Press down the time segments around the circumference. Red
markings will become visible, indicating the preselected heating
time at which the appliance automatically starts to heat. If the
required room temperature has been reached during the heat-up
time, the appliance switches off. It starts again if there is a further
heat demand and will continue doing so until the selected heating
time has elapsed. This process is repeated daily. The heating time
can be adjusted at any time if required by pressing time segments
up or down.
5.2

Stopping heating / Frost protection

f Turn the temperature selector fully anti-clockwise.
In this setting, frost protection is only ensured if the rocker switch
is positioned for "Standard operation". The heater starts automati-
cally if the room temperature drops below the frost protection
temperature.

6.1 Starting heating
f Turn the temperature selector clockwise to the required
setting.
The temperature is infinitely adjustable. The appliance switches
off as soon as the selected room temperature has been reached.
You can use the rocker switch to choose between the following
two outputs with matched fan motor speed:
Base heating stage
Set the rocker switch to "I". Provided that the appliance has been
switched on via the temperature selector, it will heat with an
output of 1000 W at the slow fan stage.
Note
Never operate the appliance at standard heating stage I,
if the room where the appliance has been installed has
cooled down severely.
f If the room has cooled down severely, switch the ap-
pliance to rapid heating stage II in order to ensure
normal appliance operation.
Quick heating stage
Set the rocker switch to "II". Provided that the appliance has been
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.
