Optimum control requiresaccurate 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 hasnt 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, theindoor 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

Mounting guidelines for outdoor temperature sensors

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)

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

Always attach the sensors to the coldest

wall of the building (normally on the

north side). They should not be exposed

to morning sunlight. The sensors are best

placed in the middle of the building or in

the heating zone but at least 2.5 meters

above the ground.

Motion detectors

Mounting guidelines for motion detectors in a room

Do not expose motion detectors to direct sunlight Make sure that the sensors cannot be affected by air

turbulences, e.g., do not install them near fan heaters Fluorescent and incandescent lamps in the detection zone

must be placed at least 1 3 meters away from the sensor Mount the motion detector laterally to the direction of

walking

Mounting guidelines for motion detectors on a building

Do not expose motion detectors to direct sunlight Avoid potential sources of interference, such as nearby hot

air flows; mount below and not above a luminaire Make sure that there are no shrubs or trees in the detection

zone of the motion detector Do not mount on moving supports such as poles

Presence detectors (incl. brightness sensors)

Mounting guidelines for presence detectors

Make sure that the workplace is right in the detection zone

of the presence detector without any obstacles such as

shelves, plants, glass walls, etc. blocking the detector Keep in mind that moving machines, plants and animals in

the detection zone will be interpreted as movement Avoid sources of rapid changes in temperature or light, such

as fans, incandescent or halogen lamps; air flows and light

in the detection zone simulate movement Mount at least 50 cm away from cables and radiators

Mounting guidelines for presence detectors with

brightness sensors

Avoid light sources that switch on or off, such as TVs,

in the detection zone; they simulate movement 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

Mounting guidelines for room sensors

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

To ensure accurate readings, it is a good idea to keep the

following in mind during installation:

Clearances between the cable (4) or

plastic hose and the installation pipe (5)

need to be sealed. Otherwise, inefficient

air circulation will occur, causing mea-

suring errors.

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.

In building control, open communication is important. It allows

easy and secure integration of third-party systems on all levels.

Support for multiple open standards ensures communication

and facilitates efficient engineering. It also makes system

maintenance and interoperability easier, thereby providing

greater investment protection.

Siemens therefore supports different communication protocols

in building automation without limiting this to proprietary

protocols or a single standard.

As a result, a wide range of communicating devices can be

used. They form the basis for energy-efficient room and

building automation.

Commissioning a KNX/Ethernet system (LAN)

In GAMMA instabusprojects, 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 instabusvia the IP interface and start the download.

With a LAN connection, the download takes only half as long

as it does with USB.

Benefits

Convenient planning, configuration, commissioning and

diagnosis with ETS (Version 3 or later) Simply connect your notebook and start the download The download is twice as fast, which substantially shortens

the commissioning time

Follow these steps

Connect the IP interface to the KNX bus Connect the notebook to the IP interface using the Ethernet

crossover cable

Start the download

You will need

Commissioning a KNX/Ethernet system (WLAN)

In GAMMA instabusprojects, the devices are commissioned

after installation. First, the physical addresses must be as-

signed. 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. Thats the

reason why two people usually perform the commissioning.

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.

Benefits

Coupling KNX lines via Ethernet (LAN)

The new KNXnet/IP standard enables KNX telegrams to be

transmitted via Ethernet (LAN), which leads to new appli-

cations and solutions.

Existing network infrastructure and technologies are used

to transmit KNX data over longer distances.

Connections between buildings and between floors can

be clearly and easily implemented with KNXnet/IP.

Benefits

Remote access to KNX via the Internet (DSL)

During the course of completing a building project or after

the building goes into operation, changes, such as the light-

ing 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.

Now you can make these changes immediately and very com-

fortably 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.

Benefits

Change parameters quickly

Save driving time and costs High data security Flexibility boosts your image in the customers eyes

Follow these steps

Connect the IP interface to the KNX bus Connect the IP interface to the LAN Configure the VPN DSL router or dial-up router

KNX visualization via Ethernet (LAN)

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.

Remote visualization serves best for managing multiple prop-

erties at the same time and checking parameters as cooling

temperature, fan failure or temperature and humidity.

Follow these steps

Connect one IP interface to KNX for each property Connect the IP interface to the LAN Configure the IP interface via the Internet/intranet for

accessibility Define the IP interface in the visualization or ETS software

Monitoring properties with KNX via Ethernet (LAN)

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.

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.

Benefits

Central status messages for distributed properties

Less maintenance required Optimization of maintenance costs

Using DALI luminaires with easy KNX commissioning

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 instabusdevices without any knowledge of DALI or

DALI commissioning procedures.

The switch/dimmer actuator switches and dims eight indepen-

dent groups of fluorescent lamps with dimmable ballasts and

DALI interfaces. Up to eight DALI ballasts can be connected to

each of the eight channels.

Wireless remote control (KNX/EnOcean)

In some areas of a building, cables are not wanted. In other

cases, laying cables is too labor-intensive or not possible at all.

Maintenance-free switches and room devices based on the

open EnOcean communication standard are the ideal solution

for these applications.

Benefits

Battery-free and thus environmentally friendly and

maintenance-free Communication via open standard Can be easily glued/screwed to any surfaces Can be upgraded without new cables

Can be connected to GAMMA instabus: KNX via KNX/

EnOcean gateway

Follow these steps

Connect the KNX/EnOcean gateway to the KNX bus

Configure and program the KNX/EnOcean gateway in ETS Program the EnOcean devices

You will need

KNX/EnOcean gateway Further EnOcean devices, depending on the application

Lighting/sun protection applications: EnOcean wall trans-

mitter with energy generation at the press of a button

HVAC applications: room operator units with solar cells

Range planning for EnOcean wireless systems

Tip 1

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%

Tx: Transmitter, Rx: Receiver

Tx Rx

Tip 2

An adequate range reserve ensures robust and reliable installa-

tion 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

Tip 3

Important factors that reduce the radio range:

Metal partitions or hollow walls with fiberglass insulationon metal foil

False ceilings with panels made of metal or carbon fiber

Steel furnishings or metal-coated glass

Switch 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 4

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.

Tip 5

An extremely robust wireless system can be created by

implementing a redundant radio reception path. This canbe achieved by programming two adjacent wireless gateways

for parallel reception of a wireless transmitter.

Tip 6

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.

protocol on the Internet.

PMR Private Mobile Radio is a radio application for

the layperson. It is assigned the UHF ultra-high

frequency band (446.000 446.100 MHz).

PoE Power-over-Ethernet (PoE) refers to a method

for supplying power to network-enabled devices

over the 8-wire Ethernet cable.

SELV 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 authenticatedduring setup, and by simultaneously encrypting

the data.

WLAN Wireless Local Area Network, e.g. a local radio

network.
