New Saia®PCD7L79xN room controller for «Perfect Fit» automation
With lean room automation, buildings operations
are greener and more economical. They are greener
because CO
2
emissions are reduced owing to lower
energy consumption. They are more economical be-
cause lower energy consumption means lower oper-
ating costs and simple and flexible lean automation
requires fewer staff.
Two factors in building technique can influence en-
ergy consumption:
–
the equipment of the building: Reducing energy
demand through efficient automation and control
–
operation of the building: The reduction of energy
consumption, by ensuring that each individual
room only uses as much energy as is required, can
be achieved through the monitoring, optimization
and communication of system components.
Potential savings in energy costs
From the perspective of room automation, saving
energy means avoiding waste. Cooling or heating
with the window open, having lights switched on
when there is plentiful daylight, and air condition-
ing unused rooms are examples of wasted energy. If
this waste can be eliminated using a suitable room
automation system, energy consumption is reduced
by up to 60 per cent, without limiting the comfort or
security of the rooms being used.
Additional increase in productivity through
room automation
The user is at the centre of room automation, which
should ensure maximum added value and maximum
comfort. Efficient single-room control gives offices,
classrooms, hotel rooms and shops optimal room
conditions in terms of comfort and cosiness. This can
be customized for the user or for typical use. The key
parameters of lighting, temperature and air quality
are controlled by the room automation system.
Saia®Room control system effects
The greatest potential for saving energy
is in the field of networked room auto-
mation and its parameters of use. The
PCD7.L6xx and PCD7.L79xN room control
families ensure optimal synergy between
HVAC, lighting and shading thanks to ex-
cellent networking functions.
More energy efficiency, without loss of comfort.
Fewer qualified personnel, less CO
2
emissions and lower operating costs.
What does that have to do with room control?
What does lean mean in terms of room automation?

The multiple settings of PCD7.L79xN ensure that the
optimal balance is achieved between energy saving
and comfort. This ensures that energy consumption
is reduced significantly, while increasing user com-
fort.
Simple commissioning
The new compact PCD7.L79xN room
controllers are suitable for standard
applications, where the emphasis is
on good value for money, for example,
heating and cooling applications with
combinations of radiators, floor heating
and integrated cooling systems.
The room controller’s integral software
modules have parameters that can easily
be set for the most diverse application
areas by means of the automation sys-
tem’s integral function blocks (FBoxes).
That makes changeover simple, quick
and safe. Since no programming knowl-
edge is needed, fewer qualified person-
nel are needed during commissioning
and servicing.
Cost-saving installation and easy
replacement
The compact room controller is fitted
directly onto the wall, so that no terminal
box is needed. Wiring and installation is
simple, saving additional instal-
lation costs. Thanks to the
pluggable housing
(
electronics) on
the base plate,
the devices can
be easily replaced
without the need
for costly and error-
prone rewiring.
A diverse range of applications
The application program for various types of
facility are predefined in the controller and can be
activated via the configuration settings.
Serviceability thanks to a
base plate with pluggable
terminal boxes
