Optimum control requires
accurate measurements
A control operation is only as good as the measuring accuracy of the sensors which detect
the control variable (temperature, humidity, pressure, etc.) and transmit it to the controller
as an actual value. While this process hasn’t changed, the measuring technology and methods
for mounting sensors are more cutting-edge than ever before.
Legal regulations increasingly appeal for the economic use of energy. At the same time, the
indoor climate must meet stringent requirements. Both requirements can be fully met only
if all necessary measured data are available and the sensors remain absolutely reliable year
after year. Sensors thus form a key basis for optimizing energy efficiency in rooms.
Professional and high-quality products are needed to meet this goal – along with a few
practical basic rules.
This manual was written by practitioners for practitioners and has become a popular and
indispensable reference book over the last few years.

Outdoor temperature sensors
Depending on the application, place outdoor temperature
sensors as follows:
For control
The sensors should be mounted on the
outer walls with the windows of the
main living areas. However, they should
not be exposed to morning sunlight.
In case of doubt, you can mount these
sensors on the north or northwest wall.
For optimization
■ ■ Do
not expose to direct sunlight
■ ■ Do not mount on facades with a great deal of ascending heat
■ ■ Do not attach to walls in front of a chimney
■ ■ Do not mount on eaves or a balcony
■ ■ Do not place over windows
■ ■ Do no mount over ventilation shafts
■ ■ Do not paint over sensors
■ ■ Mount sensors in an accessible location
(so they can be checked)

■ ■ Avoid light sources with a high infrared component;
they distort the daylight measurement
■ ■ Make sure that the brightness sensor measures only indirect,
reflected light; direct sunlight distorts the measurement
results
■ ■ Avoid shiny surfaces that are highly reflective
■ ■ Keep in mind that thermal protection glass can influence the
daylight measurement; the tripping value will be lower

Room sensors for temperature, humidity and air quality
To ensure accurate readings, it is a good idea to keep the
following in mind during installation:
When mounting on massive walls (1)
made of steel, concrete, etc., you need to
place thermal insulation (2) between the
room sensor (3) and the wall.

Mounting guidelines for room sensors
Clearances between the cable (4) or
plastic hose and the installation pipe (5)
need to be sealed. Otherwise, inefficient
air circulation will occur, causing measuring errors.
■ ■ Mount
room sensors in the living area at a height of
approx.1.5 meters and a distance of at least 50 cm
from the nearest wall
■ ■ Do not expose to direct sunlight
■ ■ Do not mount on external walls
■ ■ Do not place in alcoves or on shelves
■ ■ Avoid placing near lamps or fans
■ ■ Avoid walls in front of radiators
■ ■ Do not mount in the immediate vicinity of doors
■ ■ Do not cover with curtains

In GAMMA instabus projects, the devices are commissioned
after installation. Once the physical addresses have been
assigned, application programs, parameters and addresses are
loaded to the devices. This can take some time, particularly in
large projects with many devices.
The LAN connection from Siemens makes it all go much faster,
saving you time and money. Just connect your notebook to the
GAMMA instabus via the IP interface and start the download.
With a LAN connection, the download takes only half as long

In GAMMA instabus projects, the devices are commissioned
after installation. First, the physical addresses must be assigned. To do this, select the device in ETS on the notebook
and press the programming key on the device. If you have
various devices at different places such as flush-mounted bus
coupling units, this can require intensive walkways. That’s the
reason why two people usually perform the commissioning.
You will need
■ ■ An
IP interface with an additional power supply or
Power-over-Ethernet, if necessary
■ ■ WLAN router
■ ■ WLAN-enabled notebook
■ ■ ETS (Version 3 or later)
You can save yourself this extra work by connecting your
notebook wirelessly to the KNX bus via WLAN. This lets you
move about freely during commissioning ‒ just take your
notebook with you to each room.

During the course of completing a building project or after
the building goes into operation, changes, such as the lighting times, are often requested. Up to now this meant making
an appointment with the customer, driving to the property,
changing the parameter settings, driving back again.
You will need
■ ■ An
IP interface, with an additional power supply or
Power-over-Ethernet, if necessary
■ ■ VPN DSL router or ISDN/analog dial-up router
■ ■ ETS (Version 3 or later)
Now you can make these changes immediately and very comfortably from your office. A LAN/Internet connection lets you
easily parameterize the installation remotely. Most buildings
already have a LAN and Internet connection. Since access is
from outside the building, a VPN DSL router or dial-up router
must be used to ensure data security.

When retrieving large numbers of data points cyclically for
visualization in large projects, it can take a long time to update
the values.
Use your LAN as the main and backbone line and connect your
PC for visualization to the LAN. This makes visualization up to
200 times faster ‒ and you can monitor larger numbers of data
points. You no longer need any data concentrators, and the
data volume is also no longer important.

Property 3
Some distributed properties need to be checked regularly for
certain conditions and maintained accordingly. Such checks
include the fill levels of oil tanks in distributed apartment
buildings or the operating hours of electrical consumers.
You will need
■ ■ IP
interface, 1x per property, with an additional power
supply or Power-over-Ethernet, if necessary
■ ■ IPAS ComBridge Studio visualization software
■ ■ ETS (Version 3 or later)
These states can now be reported centrally to any location,
eliminating the need for cyclical inspection walkthroughs.
Instead, maintenance is carried out precisely when needed,
e.g., refilling the oil tanks. You can even select the best time
to do this, for example, when oil prices are lowest.

Ballasts with a DALI interface are used in lighting controls,
e.g., to report lamp failure. The switch/dimmer actuator now
makes it possible to completely replace DALI devices with
GAMMA instabus devices without any knowledge of DALI or
DALI commissioning procedures.
The switch/dimmer actuator switches and dims eight independent groups of fluorescent lamps with dimmable ballasts and
DALI interfaces. Up to eight DALI ballasts can be connected to
each of the eight channels.

The range is limited by wall materials that block free-field
propagation (300 m):
■ ■ Wood, plaster, uncoated glass, no metal
0 – 10%
■ ■ Brick, press boards
5 – 35%
■ ■ Ferro concrete
10 – 90%
An adequate range reserve ensures robust and reliable installation in the building.

Recommendations based on practical experience:
■ ■ > 30 m under excellent conditions: large free space, optimal
antenna design and good antenna positions
■ ■ Planning reliability with furnishings and people in the room,
through up to 5 plasterboard drywalls or 2 brick/gas concrete
walls:
> 20 m for transmitter and receiver with good antenna
design and good antenna positions
> 10 m
• for receivers built into a wall or corner of a room
• for small receivers with internal antennas
• if receivers are mounted on metal together with switches
• if wire antennas are located near metal
• in a narrow hallway
■ ■ Vertical penetration of 1 ‒ 2 ceilings, depending on the
reinforcement and antenna designs

■ ■ Important
Based on experience with practical applications, unfavorable
conditions and all typical shortcomings must be planned for.
Planning a range radius of 10 ‒ 12 m provides adequate
safety – even if common changes to the ambient conditions
are made later on (lightweight walls, furnishings, people in
the room, etc.) Due to the reserve, one meter more or less
hardly matters when it comes to positioning the gateway as
well as during later execution.
factors that reduce the radio range:
–M
etal partitions or hollow walls with fiberglass insulation
on metal foil
–F
alse ceilings with panels made of metal or carbon fiber
–S
teel furnishings or metal-coated glass
–S
witch mounted on a metal wall
(typically 30% loss in range)
– Use of metallic switch plate series
(typically 30% loss in range)
■ ■ Fire walls, elevator shafts, stairwells and supply areas should
be regarded as barriers.
■ ■ Barriers can be removed from the radio shadow by
repositioning the transmitting and/or receiving antenna –
or by using a repeater.

Tip 6
An extremely robust wireless system can be created by
implementing a redundant radio reception path. This can
be achieved by programming two adjacent wireless gateways
for parallel reception of a wireless transmitter.
Even with careful planning, range tests using a field strength
test instrument should be carried out on site during installation.
Unfavorable conditions can be improved by suitably repositioning
the device (antennas) or by using a repeater.

Safety extra-low voltage
VPN
VPNs (Virtual Private Networks) are used to set
up a secure subnetwork over an open, unprotected
network (Internet, radio network), in which the
communication is protected against monitoring
and access by external users. This is done by
“tunneling” the data traffic over a VPN server,
where the connections must be authenticated
during setup, and by simultaneously encrypting
the data.
WLAN
Wireless Local Area Network, e.g. a local radio
network.
