2. Function of the storage heater

General description
A storage heater stores the heat it needs for the next
day in its storage core, usually over night. This means
that electrical energy is saved at a time when the elec-
tricity distribution grids run by the energy suppliers
are not fully utilised.
In certain regions, the storage heater can be set so
that additional heat is stored at defined times of the
day. The majority of the energy is usually charged and
stored over night, however.
When the storage heater is in operation, cracking
noises can sometimes be heard. This is completely
normal and is due to temperature changes in the stor-
age core.
First heat up
As with all new devices, new materials in the heating
device can give off a slight odour in the first days of
operation.
Please ensure that there is sufficient ventilation.
Thermal storage
The quantity of thermal energy (charge) stored in the
heating device core is determined by the load control-
ler integrated in the device. The user has several op-
tions for operating the load controller:
Weather-dependent charging with central charge
control
Room-dependent charging
Manual charge reduction
Weather-dependent charging
For this, a central charge control device is fitted in the
distribution with outside temperature recording
(weather sensor).
In this configuration, the charge quantity is deter-
mined based on the user entries and the weather con-
ditions.
Manual charge reduction
This enables the user to adjust the charge quantity in
10% increments if no central charge control is pres-
ent.
In this configuration, the heating device charges the
percentage value set by the user as a maximum, re-
gardless of the weather and room conditions.
Room-dependent charging
If this mode is activated, the charge electronics calcu-
lates the charge quantity based on the room temper-
ature conditions to fulfil the heat consumption of the
user as effectively as possible.
EN-6
Heat output
The room temperature control takes place via the
room temperature controller integrated in the heating
device as standard, but can also take place via a room
temperature controller mounted externally.
The room temperature controller is a separate item
which is not included in the scope of supply of the
product.
The desired configuration is set up by the installer.
The quantity of thermal energy output by the storage
heater is regulated automatically by the room temper-
ature controller. If the room temperature falls below
the set value, the room temperature controller
switches the fan of the storage heater on automati-
cally. The heating device also has other options. The
most important options are outlined briefly below:
Timer week program
Time-dependent specification of comfort and energy
saving mode. The desired room temperature can be
set in comfort mode. In energy saving mode, the room
temperature set for comfort mode is lowered auto-
matically.
Auxiliary heating (optional)
If the stored charge is not sufficient to heat the room
up to the desired temperature, the AUXILIARY HEAT-
ING function provides additional heat.
NOTE
This function can only be used in conjunction with the
AUXILIARY HEATING accessory.
Open window detection
The room heating device is equipped with a monitor-
ing function that detects whether unnecessary en-
ergy is being consumed due to an open window. In
this case, the heating device reduces the heat output.
Adaptive startup
This function guarantees that the set room tempera-
ture is achieved exactly at the start of comfort mode.
