Caution!
Material damage caused by frost!
If you do not ensure adequate prost protec-
tion for your heating installation in winter,
this can result in damage to the building and
to the heating installation.
In winter, make sure that adequate frost
protection is maintained.
Operating the heating system in set-back mode
Reduce
the room temperature at night and in your absence.
The simplest and most reliable way is to reduce the
room temperature by means of the controller with indi-
vidually selectable timer programmes.
Target room temperature
Set the target room temperature only as high as would
be necessary for your comfort level. An extra degree
would mean increased energy consumption of about
6%. Adjust the room temperature according to the pur-
pose of use of the room. For example, normally,
bedrooms or seldom used rooms are heated to 20 °C.
Uniform heating
Often, in an apartment with central heating, only one
room is heated. Adjacent rooms are also heated without
regulation by the enclosing surfaces of the room, i.e.
walls, doors, windows, roofs and floors, which means
that an unwanted loss of thermal energy occurs. The
capacity of the heating element of this one heated room
is obviously not enough for such an operating mode.
Consequently, the room can not be heated satisfactorily
and an uncomfortable feeling of coolness prevails (the
same effect is produced when doors between heated or
unheated or slightly
heated rooms remain open).
This is false economy: The heating is in operation and
still the room temperature is not comfortably warm.
Greater heating comfort and a more practical operating
mode is achieved when all rooms in an apartment are
heated uniformly and in accordance with their usage.
Thermostatic valves and room thermostats
Thermostatic valves on all radiators maintain the room
temperature exactly once set. You can adjust the room
temperature to suit your individual requirements and
ensure economical operation of your heating installation
using the thermostatic valves in combination with a
weather-compensated controller.
This is how a thermostatic valve works: When the room
temperature rises above the value set on the sensor
head, the thermostatic valve closes automatically. When
the room temperature falls below the set value, the
thermostatic valve opens once more.

Do not obstruct the controller
Do not obstruct your controller with furniture, curtains
or other objects. It must be able to detect the circula-
ting room air without hindrance. Covered thermostatic
valves can be fitted with remote sensors and thus conti-
nue to work.
Installation of a weather-controlled heating control-
ler
Weather compensators regulate the heating supply tem-
perature according to the outside temperature. Thus it
is ensured that heat in excess of what is required at the
moment is not generated. In addition, desired heating
and set-back phases (e.g. at night) are automatically tur-
ned on and off by using integrated time programmes.
Weather compensators combined with thermostat val-
ves are the most economical form of heating regulation.
Ventilating residential spaces
During the heating period, open windows only for venti-
lation and not for temperature regulation. A brief,
forced change of air is more effective and energy-saving
than windows that are kept open for a long time. Close
all the thermostatic valves in the room during ventila-
tion.
These measures guarantee adequate air circulation
without unnecessary loss of energy and cooling off.
