For you and for the environment
The ideal room climate just the way you want it: room automation systems from
SAUTER let you easily control the various different systems for heating, cooling,
lighting, shading and ventilation. You can adapt the control and regulation
processes to suit the activities taking place in the building during the day and
at night. This means that you can reduce your energy consumption, costs and
CO
2
emissions whilst enjoying the ultimate in convenience and well-being.
SAUTER creates ideal conditions in every room
In offices, hospitals, museums, schools or any other type of building, SAUTER
adapts room automation to the specific room usage for every customer and
every construction project. The result is the creation of comprehensive, tailor-
made solutions based on long-standing experience in room automation.
Experienced specialists will provide full support right from the planning phase,
and SAUTER continues to help you to optimise your energy requirements even
after the room automation system has been put into service. The SAUTER
ECO
10
programme is a package that was developed specially for this purpo-
se, reflecting SAUTER’s dual responsibility: low costs for its customers and low
emissions for the environment.
I want to make savings, but not at the
expense of convenience. Which is why I’ve chosen
room automation from SAUTER.

A change in room temperature of
1°C influences the energy consump-
tion for heating/cooling by 6% and
reduces CO
2
emissions by around
2 kg of CO
2
per square metre of
the energy reference area. For ex-
ample, a medium-sized school with
about 25 classrooms would redu-
ce its emissions by approximately
3,200 kg of CO
2
per annum.

How intelligent room automation works.
Demand-led control for your rooms.
Rising energy costs make energy-efficient buildings all the more attractive.
Extensive savings potentials are now attainable thanks to modern room automa-
tion. For instance, demand-led technology can achieve reductions of between
30% and 70% compared to standard consumption levels. This calls for a room
automation system that automatically controls heating/cooling, lighting, shading
and ventilation. How does that work? Very simply, thanks to SAUTER.
Sensors and actuators
Sensors for temperature, brightness, occupancy and CO
2
detect the main indoor
conditions and enable the room automation station to control, for example, the
heating and cooling valves, the lighting, the blinds and the ventilation dampers
very accurately indeed.

Example of use
Room functions

Two examples of general functions are time programmes and occupancy
detection (functions that are adaptable to actual room usage)

Brightness concept, e.g.: dimming the lights when daylight is sufficient; tem-
porary lighting depending on room utilisation rates; blind control to protect
against glare; and scenario control for predefined room usage purposes

Two examples of functions for controlling the indoor climate are window
monitoring and the control of sun blinds to support temperature control

Demand-led room ventilation
Control
Room operating units from SAUTER can control the room automatically or crea-
te customised preferences at the touch of a button.
Design
Whether wired or wireless, the visual appearance of the control elements can,
of course, be adapted to match the interior design of the room.
Communication
The room automation station communicates with the primary plant and provides
information on energy requirements, which ensures that the energy provision is
controlled according to demand (load-dependent control of inlet temperature).
6
Perfectly combined
In choosing room operating units from SAUTER, you get an ideal combination
of technology and design. You can apply functions to two, four or six buttons
and have information on room temperature, setpoint, time or date available at
a glance. You can label the units with text and symbols as you wish, and there
are no limitations to installation or use. The units are mounted with the help of a
frame which, thanks to its standard inner dimensions of 55 x 55 mm, can come
either from the SAUTER range or from the range of light switches from a third-
party manufacturer. Therefore, the room operating units can be easily matched
to the decor, and even unusual design requirements can be met.
Functions
Depending on their type, the room operating units have the following functions:

Temperature measurement

Room setpoint adjustment

Setting of operating mode

Fan control

Control of lighting installations with dimming function

Control of window blinds

Display functions: occupancy mode, fan speed, date/time, various actual
values
Room operating units from SAUTER –
as varied as your rooms.
7
Wireless room operating units
Wireless room operating units from SAUTER enable you to control a wide
range of functions easily and intuitively from a central location. Miniature solar
cells provide the operating units with energy, so no batteries are required.
The installation of wireless components is simple and cost-effective, since there
are no cables to lay. The units can be fitted using adhesives or screws, making
them suitable for use in modern glass or concrete structures, and in historical
buildings. Furthermore, their design can be matched to the decor.

Flexibility is never a problem thanks to intelligent oom management.
The ability to respond quickly to changes in room usage is important in buil-
dings with flexible room utilisation, such as offices or shopping centres. In
contrast to a room-orientated concept, where room usage is fixed and devices
are installed room by room, a flexible concept is based on room segments,
which is unaffected by how the floor space is subsequently used.
The advantage of this concept is the ability to adapt all of the room’s techni-
cal functions quickly and cost-effectively to changes in the room layout. The
adaptation process itself can be carried out during normal operations with no
interruption to the system. In addition to room and field devices, the EY-modulo
automation station also contains function modules that are specifically desig-
ned to facilitate changes in room usage and the associated demands on air-
conditioning, lighting and shading. Therefore, full flexibility with regard to room
management is guaranteed.
Easy and convenient: rapid adaptation
to changes in room usage.

Boost your energy efficiency with
room automation.
European Standard EN 15232
European Standard EN 15232 has set the bar with regard to building automa-
tion (BA) for many years. The objective is to improve the energy efficiency of
buildings. The directive categorises buildings in classes A to D based on their
level of automation and assigns functions to buildings that must be controlled by
their respective automation system. Class C is defined as the standard.
BA efficiency factors are assigned to each class; these factors relate to total
energy consumption and indicate the savings potential that could be achieved
through building automation. Using class C as a basis, the directive describes
around fifty measures to increase energy efficiency so as to attain energy
classes B and A. Advancement to a higher efficiency class is possible only if
room automation is integrated in the building automation system. For instance,
a class C building automation system for regulating the air flow at room level
requires a fixed time programme, whereas a class B system is based on
occupancy and class A is demand-led. Savings of up to 30 per cent could be
achieved by implementing the necessary measures to upgrade a class C buil-
ding automation system in an office block to class B in conjunction with those
measures that could be implemented in accordance with class A.
