OPERATION

EQUIPMENT DESCRIPTION

3. Equipment description

Properties

Electrically generated heat is stored with this appliance. The electrical heat is generated when the power supply utility enables the supply of cheaper off-peak power. The times when this supply is enabled depend on the relevant power supply utility. The times when it is enabled are predominantly at night. Subject to the required room temperature, the stored heat is transferred to the room as hot air via a fan, and partially via the appliance surface.

OPERATION

CLEANING, CARE AND MAINTENANCE

4.3 Factory settings

4.3.1 Heat store

The degree of heat storage (charge) is set via the charge controller (adjustable with rotary selector 3). For this, a difference must be made between the operation of appliances with or without a central, weather-compensated charge control system. The weather-compensated charge control system is located in the control panel.

If a central, weather-compensated charge control system is not installed, set the charge controller as follows:

Setting to stage 1 corresponds to approx. 1/3 of full charging (spring/autumn).

Setting to stage 2 corresponds to approx. 2/3 of full charging (mild winter days).

Setting to stage 3 corresponds to full charging (winter days). Setting to stage 0 corresponds to no charging. Once you have familiarised yourself with the appliance, you will

be able to ﬁnd the correct setting as appropriate. If a central, weather-compensated charge control system is

installed, set the charge controller to stage 3. The weathercompensated charge control system then provides the correct charge. For differentiated control of individual appliances, you can also manually match the charge volume to the charge controller, if a charge control system is installed.

5. Cleaning, care and maintenance

If a pale brownish discolouration appears on the appliance casing, wipe this off as soo n as possible with a damp cloth and hot soapy water. Clean the appliance when cold with ordinary cleaning products. Avoid abrasive or corrosive cleaning products. Never spray cleaning product into the air slot.

5.1 Cleaning the ﬂuff ﬁlter

Important information Clean the ﬂuff ﬁlter in the air inlet grille regularly. This will ensure trouble-free discharging of the appliance. If a ﬂuff ﬁlter is added, switch OFF the fan.

To clean the ﬂuff ﬁlter, proceed as follows:

»Remove the air inlet grille from the catch springs by pulling

forwards at the bottom, and release it from the upper locking device by lifting slightly.

Removing the air inlet grille

ENGLISH

Please read carefully. Observe the instructions of the charge control system or group control unit.

4.3.2 Heat transfer

The heat transfer (discharge) is regulated via a room thermostat, either mounted on the wall or integrated inside the appliance. This is available from Stiebel Eltron as a special accessory.

Set the required room temperature at the room thermostat, which then automatically regulates the heat transfer via the fan, so the set room temperature is constantly maintained.

Please read carefully. If you will be away for several days during a very cold period, we recommend leaving the room thermostat switched on, to maintain a room temperature of e.g. 10 °C, so the building or room does not cool down (frost protection).

»Push the ﬂuff ﬁlter out of the grille, e.g. with a screwdriver, and

clean it with a brush, vacuum cleaner or similar.

INSTALLATION

SAFETY

7. Safety

7.1 Country-speciﬁc safety information

All required steps to complete commissioning must be carried out by a qualiﬁed contractor. During this process, these installation instructions must be observed.

We guarantee trouble-free function and operational reliability only if the original accessories and spare parts intended for the appliance are used.

7.2 Instructions, standards and regulations

Risk of damage. Observe the type plate. The speciﬁed voltage must

match the mains voltage. Size the equipment according to the rated consumption

of the appliances.

Note Observe the Building and Garage Regulations [or local regulations].

Danger of electrocution! All electrical connection and installation work must be conducted in accordance with VDE regulations (DINVDE0100) [or local regulations], the rules of your local power supply utility and relevant national and local regulations.

been removed by the contractor, by pressing the button in the centre of the high limit safety cut-out.

Cutaway

ENGLISH

Danger of electrocution! Connection to the power supply is only possible as a permanent connection.

The appliance must be able to be separated from the mains power supply by an isolator that disconnects all poles with at least 3 mm contact separation.

Important information Secure the appliance to the wall or ﬂoor in such a way as to ensure stability.

8.2 Factory settings

The appliance connection is wired to the maximum output (100%). If jumpers at the terminals are moved or removed, the connected load can be matched.

8.3 Design operation

The storage blocks are heated via the heating elements between the rows of storage blocks. The charge can be inﬁnitely adjusted with the charge controller. The start and duration of the charge time are set by the local power supply utility.

Two integral protective thermostats and a high limit safety cut-out prevent the appliance overheating. The protective thermostats switch back on automatically, but the high limit safety cut-out must be switched back on after the cause of the fault has

The stored heat is transferred via a fan, and partially also via the appliance surface. For this, the room air is drawn in by the fan through the air inlet grille, and released through the air ducts in the storage blocks, which heats it. Before the hot air produced in this way is released via the air outlet grille, it is mixed with cooler room air via two mixing air dampers, so the expelled air does not exceed the highest permissible temperature. The position of the mixing air damper, and thus the mixing ratio of the air, is regulated via a bi-metal controller.
