Siemens electric heater user manual
Hide thumbs


This heater, including additional equipment, is develo-
ped and manufactured in conformity with the EU-
Directives on Low Voltage Devices (73/23/EEC) and on
Electromagnetic Compability (89/336/EEC).


Take great care of these instructions for use, and pass them
on to any future owner of the heater.
If the appliance is damaged, the supplier must be notified
immediately, before installation takes place.
If a fault occurs, disconnect the appliance from the mains
supply (by switching off the fuse or unscrewing it, as
The appliance must be used only for heating homes or simi-
lar places. It is suitable only for domestic use in houses or for
similar purposes in closed rooms.
In installation areas, there must be no use of substances
that could cause ignition, explosion, or that produce
vapours that could cause these effects, because of the
high temperature inside the appliance. In such cases (for
example, gluing down of floor coverings), one must ensure
in advance that the appliance has been cooled down to
room temperature.
The functional surfaces, especially the air circulation
grilles, heat up during operation. These functional surfaces
must therefore be secured so that they cannot be touched
by children or people who are ill or disabled.
Do not put any objects into the openings of the appliance - this
can lead to functional problems, and the object might catch fire.
Taking down the appliance and disconnection from the mains
supply must be done only by a suitably qualified person.
Caution! When the appliance has been connected up and
switches on automatically while you are out, danger can ari-
se. For example, a heater that in the meantime has been
covered, or had the setting changed, could start a fire.
2. Installation, clearances, connection
The heater Typ NC2 9..-1A must be installed by an authorized
and sutiably qualified person.
The wall heater must be installed horisontally only. Position
the heater in such a way that inflammable objects cannot be
set alight. You may attach the heater to wooden walls.
The minimum clearances must be maintained. The clearance
from easily inflammable articles such as curtains, upholstered
furniture, etc., is 100mm. Take special care to ensure that air
can flow freely in and out, above and below the heater.
Certain types of light vinyl (PVC) floor coverings and varnish
for parquet floors can become discoloured when subjected to
temperatures above 35° C. With such types of floor cove-
rings, it is recommended that the lower edge of the heater is
at least 150 mm above floor level.
The heater must not be screwed directly to the wall, but must
be hung in a wall bracket.
Do not install the heater below an electrical socket.
- Drill holes for the screws. The wall frame can be used as
a template.
- Screw the wall frame into place in the wall.
- Place the heater on the lower hooks of the bracket, and
allow it to lean forward until the hooks slide into the
openings on the lower edge of the heater.
- Press the mains supply cable into the plastic clips on the
wall bracket.
- Push the heater upwards so that it leans toward the
bracket, and the upper hooks slide into place.
3. Heating
3.1 Function of the service elements
Turn on switch A when the heating period starts.
Lamp B lights when the heater is emitting heat.
The thermostat dial C is for setting the desired room tempe-
rature, which will then remain constant.
Depending on where the heater is installed, it may happen
that the room temperature and the temperature shown on the
thermostat dial do not agree.
In this case we recommend that the adjustment wheel is
adjusted as follows:
Turn the heater on. Turn the thermostat dial up to the maxi-
mum (the lamp lights). Turn the thermostat dial back again
until the lamp goes out. If you can see that there is a diffe-
rence between the reading on the thermostat dial and the
room temperature, make the adjustment as follows:
Hold the adjustment wheel steady, and set the dial with the
temperature settings to the appropriate value using a small
screwdriver or something similar.
Important: Wait until the heater has been on for about 24
hours before you make this adjustment.
3.2 Lowering the temperature
For regular reduction of the temperature, you can use our
energy-saving cassette 2NC9 712 (extra accessory).
Heater Typ 2NC2 9..-1A can additionally be controlled by an
external timer.
You can start the appropriate program at the touch of a but-
ton, or set the temperature reduction period on the timer (see
the connection diagram regarding connection). The room
temperature will be lowered by up to 5° C during the tempe-
rature reduction period.
4. Important information about using the heater
NB: The heater element has been coated with a protective oil
that will evaporate the first time the heater is switched on.
This means that a harmless vapour may be released when
the heater is switched on for the first time.
For your safety, the heater is protected against overheating.
If the air circulation is obstructed, for example by something
hanging or set up in front of the air grille, the heater will cut
out automatically.
After the obstructing object has been removed, the heater
will resume normal operation after about 15 minutes.
To attain full heating power, the openings allowing air to flow
in and out must be kept free of dust. Please vacuum clean
the heater before the start of the heating season.
5. Problems in operation
If the heater is not emitting any heat, first check that it is swit-
ched on and that the thermostat dial is set to the appropriate
temperature. Then check that the automatic cut-out fuse has
not tripped. If the latter applies, contact your electrician.
Specify the E-number, which you will find on the plate indica-
ting the power (upper right of the heater).
