1. INTRODUCTION
The central readings CRS 40 is used for wireless reading of data transmitted by radio heat cost indicators E
ITN 30 and radio modules for water meters E RM 30. The system is wireless, so except for the power supply
of 230 V (and possible connection to the Internet), its installation does not require any cables.
1.1. SYSTEM CONCEPTION
Our aim has always been to make the administration and service of the system as easy as possible. The
system therefore requires minimum of user actions via graphic interface. During normal operation, the
system itself processes and saves the data. Only when some problem occurs (broken electronic seal,
excessive back flow at water meter, or when heat cost allocator or radio module is not read), it automatically
an nounces error by e mail – and you can solve the situation immediately. You can also backup the data to
your computer from time to time .
1.2. SYSTEM TOPOLOGY
Reading network consists of one control unit B and several collecting units A. These units are automatically
configured to wireless network with star topology during installation. Every collecting unit A has direct radio
contact with control unit B. Communication in the whole reading network is managed by control unit, where
data are processed and stored. Control unit can be also connected to Internet. In this case it is possible to
access the data from standard browser, or to gain reading results and possible error logs by e mail.
When installing the system in smaller buildings where all read units E ITN 30 and E RM 30 can be covered
only by one collecting unit, it is possible to use unit C (independent concentrator). This unit can read the data
from heat cost allocators and radio modules, as well as to be connected to Internet.

1.3. ADVANTAGES OF THE SYSTEM
The biggest problem during the process of heat cost or water consumption billing can be incomplete data as
ratio is calculated. This can be caused by meter or allocator manipulation, its intentional damage or failure.
Situation is also complicated by changes in prices of energy or water during the year. Another problem can
arise when people move and forget to record the consumption. Time consuming inter readings or
consumption estimation must be made from these reasons in order to determine the values at specified date.
Billing company risks the reclamations and conflicts with flat users.
Thanks to the installation of Central reading system, you can get the information about heat and water
consumption every day in a year. Any errors or manipulations is quickly identified and effective correction can
be made. Also reduction of number of manipulations can be expected – tenants will learn that their
unauthorized handling are quickly revealed and brings nothing to them, only payment of service cost to put
heat cost allocators and water meters back to perfect condition.
You can also offer to your customers additional statistics and information about consumption due to big
amount of actual data. Many problems (connected e.g. with excessive consumption) can be solved already
during billing period .

3. DESCRIPTION OF THE EQUIPMENT
3.1. GENERAL DESCRIPTION OF THE EQUIPMENT
CRS 40 is a system for centralized remote reading of radio heat cost allocators (E 30 ITN) and radio
modules for water meters (E RM 30) operating in the 868 MHz ISM band. Reading network consists of one
or more collecting units A (concentrator) and one central unit B (coordinator) for coordinating meter reading
networks and sending data over the Internet (Ethernet, optional WiFi or GSM) to the remote operator. The
control unit B also serves to adjust the readings (error messages, schedule of readings and possibly base
plan). All elements of the meter reading networks communicate via wireless network. Units of the reading
network are powered from the network of low voltage of 230 V. The readings of heat cost allocators and radio
water meters are performed with daily periodicity. Users log into the system from personal computer or
mobile device via an encrypted connection using a simple web GUI. The automatic transfer of data from the
meter reading network can be done using e mail or synchronization script. CRS 40 is designed for indoor
environment (installation in residential buildings).
3.1.1. Unit type A (collecting unit the concentrator)
A unit is designed to collect data from radio transmitting devices (heat cost allocators and radio modules) and
have them forwarded to the control unit B. Unit B (coordinator) further evaluates the data, stores and
transmits possibly over the Internet. Unit A consists of a plastic box, power supply (NZCC1101), radio module
(RFCC1101) and panel antennas attached from the inner side to the cover box.
3.1.2. Unit B (Control Unit Coordinator)
The control unit B manages a group of A units, receives data, evaluates, stores, and eventually sends via the
Internet.
Unit B consists of a box, power supply (adapter), radio module (RFCC1101), panel antenna mounted on the
inner side of the lid and the module box miniature computers (OLIMEX A20).

3.4. INTERNET CONNECTION OPTIONS
To make of the advantages of central reading system CRS 40, it is necessary to connect the reading network
to the Internet. The CRS unit B therefore contains an integrated standard RJ45 Ethernet interface. Using this
interface, it can be connected directly into the domestic cabling structure (type CAT5 or higher cable with
RJ45 connector). It is also possible to use a Wi Fi USB power adapter or GSM modem.
The control unit B waits for assignment of the dynamic IP address V4 through protocol DHCP, which is
commonly used for this purpose. When the unit is required to use the address assigned by the Internet
provider, it must be specified in the Settings (more in chapter 10.5 System parameters setting).
Possible means of connecting to the Internet:
•via Ethernet network
•via Wi Fi network (Wi Fi USB adaptor must be used)
•via mobile network (USB GSM modem must be used)
Using various connection methods depends on the circumstances of a particular apartment building. If in
doubt, contact your Internet provider.
If the computer is correctly connected to the Internet and set up, it automatically initiates an encrypted
connection and allows connection with the control computer.
For more information, see chapter 5.1. Installing the unit B.
3.5. METHOD OF USE OR DISPOSAL

4. SPREADING OF RADIO WAVES
Central reading system 40 CRS works with wireless data transmission using radio waves. For proper
installation and operation of the system it is helpful to learn at least the basics of radio wave spreading.
4.1. PROPAGATION OF ELECTROMAGNETIC FIELDS
In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves of the electromagnetic field,
propagating (radiating) through space The speed of these waves in the air is close the speed of light.
Characteristic quantity is wavelength, which is approx. 35 cm at 868 MHz frequency.
Wave can band around obstacles in its way only when its wavelength is much bigger that the size of the
obstacle. Reflection and refraction happens Reflection and refraction of waves occurs at the interface
between two dielectric permittivity different environments. Part of the waves reflects, part breaks. The angle
of reflection equals to the angle of incidence. The reflection occurs even on perfectly conductive surface
(metal) because the electromagnetic radiation does not propagates in it.
In the structure of the apartment house there is a large quantity of various obstacles that have negative effect
on propagation of electromagnetic waves. It is especially any metals (arming, elevator shafts, railings, metal
foils etc.) through which the electromagnetic waves do not pass, only reflects. Also, the construction of
buldings (walls, ceilings) significantly dampens the electromagnetic waves. Therefore the propagation of the
electromagnetic walls in such buildings is rather complicated and is individual for each building.
4.2. POSSIBLE OBSTACLES TO PROPAGATION OF THE ELECTROMAGNETIC WAVES IN THE APARTMENT BUILDING
The number and placement of the repeater units must be adjusted individually for each object. Most common
obstacles are the following:
•Wired elevator shafts
•Metal sheets
•Metallic layer on windows
•Aluminum blinds
•Metal furnishing
•Large parts of furniture
•Shielding caused by electrical appliances (TV, audio, washing machine, dishwasher …)
•Equipment working permanently in 868 MHz range (baby monitor, weather station)
•Radio hobbyist

5. INSTALLATION IN THE APARTMENT HOUSE
As the radio signal spreading inside the residential building depends on many factors (see chapter 4: Radio
waves transmission), the radio contact with more distant devices is largely random and can not
be predicted completely in advance. For this reason, we recommend to install the system in the period of
more frequent transmission of read devices. It is the month following the beginning of billing period (once per
year) in year versions, or first three days after beginning of billing period day (every month) in month
versions.
The radio signal range of the radio modules for water meters is considerably larger than that of heat cost
allocators.
If the billing period is different for radio modules and heat cost allocator, we recommend to follow the billing
period of heat cost allocators.
When installing the system outside of the period of more frequent transmission, installation verification (i.e.
receiving the data from all heat cost allocators / radio modules) will probably take a longer time.
Installation duration can not be calculated in advance. The best choice is to make a “test” installation for
every building type where you can find out the best location of collecting units to cover the whole building.
The installation duration should be similar in similar buildings. For recommended installation positions in the
most common types of buildings, see chapter 12. Installation methods.
5.1. INSTALLATION OF CONTROL UNIT B
At first, find a suitable place for unit B installation (with connection to the Internet and power supply). As the
unit B contains communication software and it is used also for the saving of read data, it is recommended to
install it in the secured place (without the risk of theft). The control unit B must be also in the radio range of
all collecting units A. For recommended installation positions in the most common types of buildings, see
chapter 12. Installation methods.
Connect unit B via Ethernet cable to laptop. IP address of this laptop must be set to 169.254.123.x and
the net mask to 255.255.255.0 (see your operating system manual for more information how to set it). Then
connect to unit B using standard web browser – just enter IP address 169.254.123.123 to address line. Set
the basic parameters for remote access in <Settings> mainly the reading network name, login and
password. It is recommended to load the reading plan (necessary for system work) also in this moment. For
more information, see chapter 10. Description of graphic user interface.
Connect the unit B using Ethernet cable (RJ45 connector) directly to the Internet in residential building, to
GPRS/3G router, Wi Fi appliance or ADSL modem. The unit B expects automatic allocation of IP address
and other network configuration from local DHCP server. Allocated IP address may not be public. Static IP
address – if used – must be entered in Settings (see chapter 10.5 Setting of system parameters). Connection
to Internet is finished now. Contact your Internet provider for details of Internet access.
Mount the unit to desired place.
Warning!
Manipulate with open unit only (e.g. installation on eiling) when the power supply is off. Otherwise
the ele troni omponents an be damaged.
Warning!
Before plugging in the harging ord to mi ropro essor, make sure to plug in ba kup battery first.
Connect the unit to electric. Connection of device to electrical power network or its
maintenance can be done only by staff qualified in accordance with local legislation.

GREEN (radio module) flashes Obtaining data from the units A
5.2. INSTALLATION OF COLLECTING UNITS A
It is recommended to place one collecting unit A to every entrance of residential building. Theoretically, the
building can be covered with smaller quantity of collecting units. There can be a problem to read the data
from some read devices (radio modules for water meters and heat cost allocators) in such case. As a result,
the read device can be interpreted as missing even when it is okay and functional.
For more information about recommended installation positions in the most common types of buildings, see
chapter 13. Installation methods.
Connection of collecting unit A to control unit B must be verified at the installation site (indicated by red LED
switching off on the radio module RFCC1101 after power supply connection). It is also recommended that
unit A receives the data from read devices (radio modules, heat cost allocator). Data receiving is indicated by
green LED blinking (approx. 1 min.).
If collecting unit A is not connected to control unit B after power supply connection, try to restart unit A using
RESET button on the radio module printed circuit board (see Illustration 4: Layout of the radio module
RFCC1101).
After the actual installation of units A, it is appropriate to connect to unit B and verify successful
communication. Click to <Units A> link on main page. Here you can find the list of connected collecting units
A ,including the time from last communication with control unit B, signal strength and number of connections.
For more information, see chapter 10.4 List of units A connected to reading network.

Note:
Units A are equipped with battery supply for the installation purposes (finding the ideal lo ation and
overage verifi ation). Battery supply is only intended for installation and on e the installation is
finished, it should be onne ted to the mains. The time required for overage verifi ation may be
different in ea h obje t and annot be al ulated in advan ed.
Note:
Before the installation of the A units, please he k that the DIP swit h is set the same on the B unit
and all A units in one reading network (see Pi ture 4: S hemati s of the radio module RFCC1101)
For more information, please he k hapter 6.2. Configuration of multiple overlapping networks.

5.3. FINISHING AND VERIFYING OF THE INSTALLATION
After finishing the installation of units A and B, it is necessary to verify the correct function or reading
network. This can be done either at installation place using laptop connected directly to unit B or at office
using Internet connection (if you have already set access rights during unit B installation).
First, you should finish the setting. Set the NTP server that serves for exact time acquiring. Then, it is
essential to load the reading plan. If you upload a new plan to unit B, system is restarted automatically and
starts to check the read devices readability. We recommend to load also base of plan for easier orientation in
reports.
For more information about setting, see chapter Setting of system parameters
First step of system is reading network time synchronization. Control unit B tries to connect the set NTP
server and to get the exact time. If the NTP server is not set or set incorrectly, the system tries to connect to
some public NTP servers that are set in software by default. If the time is not obtained from NTP server (can
be caused by disconnection of unit B from Internet, or by blocking of some ports by provider), unit B get the
time from radio packets transmitted by heat cost allocators and radio modules. This way of time
synchronization is less exact and it takes a longer time.
During the time synchronization you can get the exact information by clicking to <Log> link. The displayed
messages are intended for service purpose only.
When installation verification is finished, unit B starts to receiving via units A the data from heat cost
allocators and radio modules for water meters. This data are compared with reading plan (i.e. list of devices
installed in particular building). You can watch the installation progress in a table (Illustation 6: Installation
progress). You can also open the list of devices that are already read or still not read by clicking to blue
numbers.

Illustration 5: Time synchronization of the readin network
CRS 40 V2
Installation, operation and service manual M2019/02a
The time required for installation verification can be different based on the building type and its parameters
and can not be calculated in advance. Generally, two different situations can occur:
1. Received data are complete, it means all allocators and radio modules for water meters
were read. Units A can be fasten to the finally place using 4 screws and wall plugs.
Disconnect the batteries and connect the unit A to electrical network 230 V. Note:
connection of power supply NZCC1101 to electrical power network is secured by one
fuse, connection of wires according to label (N, L) must be kept (L is secured). Connection of device
to electrical power network or its maintenance can be done only by staff qualified in accordance with
local legislation.
2. System does not find all read devices from reading plan. To solve the situation, proceed step by
step and find the cause:
a) Check the plan first, i.e. if all mentioned units are really installed and repair the reading plan
if necessary. If some read devices should be removed from the reading plan, you can add
them to “List of ignored read devices”.
b) Check if the missing devices really transmit the data. The best way how to do it is to use
mobile reading unit RFU 35 with panel antenna to make reading from another place. If you
can read heat cost allocator or radio module for water meter using RFU 35, try to find new
position for unit A. After change of unit A location, restart unit B (by new upload of reading
plan). If heat cost allocators or radio modules for water meters can not be read even with
mobile radio reading unit RFU 35, it is necessary to check it on site.

6. READING NETWORK
6.1. RF MAC READING NETWORK ADDRESS
Every produced unit of Central reading system CRS 40 is equipped with unique identification number of radio
module RFCC1101, so called RF MAC address. You can find this number on unit identification label. First
two groups of digits are unique for particular customer, next two identify particular unit.
There can be situations, when more billing companies provide their services in one housing estate (or even
in one large building). To avoid situations like that e.g. unit A of one billing company would connect to reading
network of another one, sameness of first two groups of digits is checked during connection establishment.
Warning
Only units with the same first four digits from RF MAC address (see Illustration 6: I Identifi ation
label of the unit B, Illustration 5: Identifi ation label of the unit A) an be used in one reading
network.
Units with different initial four digits of RF MAC address are not establish connection even when the setting
of DIP switch is the same. For more information, see chapter Configuration of multiple overlapping network.
6.2. CONFIGURATION OF MULTIPLE OVERLAPPING NETWORK
Mainly in the housing estate, it can happen that installation of more
reading networks in close buildings (or even in one building) is
necessary. Only installation of multiple reading networks of one
billing company with the same first four digits of RF MAC address
(see chapter 6.1. RF MAC Reading network address ) is described
in this chapter. Installation of more reading networks of more billing
companies does not require any further setting (see Illustration 8:
Overlapping networks of two billing companies).
To avoid connection of unit A to another reading network (i.e. to
another unit B), it is necessary to distinguish between such
networks.
Distinguishing between reading networks is done by DIP switch on
radio module RFCC1101 (see Picture 4: Schematics of the radio
module RFCC1101 and Illustration 7: Detail of the DIP switch). DIP
switches are set to position OFF OFF OFF OFF (0 0 0 0) by
default.
It is possible to use default configuration of DIP switch when installing the first reading network. When
installing next reading network, it is necessary to change DIP switch to another configuration on both control
unit B and all collecting units A. 15 combinations can be used, configuration ON ON ON ON (1 1 1 1) is
reserved by the manufacturer.

Warning! DIP swit h onfiguration ON-ON-ON-ON is intended only for manufa turer test purpose. It
must not be used in everyday operation. Su h units are not fun tional.
The situation shown in Illustration 8: Overlapping networks of two billing companies is only illustrative. In
practice, the range of radio equipment, especially in the building, has no circular shape (see chapter 4.
Spreading of radio waves).
Warning!
If two reading networks with the same first four digits of RF MAC address and the same
onfiguration of DIP swit hes would be started up, newly installed network will not work. It will be
ne essary to restart units B of both reading networks after hanging the DIP swit hes onfiguration

7. FIRMWARE UPDATES
Firmware is computer program specific for particular device and it is integral part of electronic appliance
(Central reading system CRS 40). Firmware is programmed to internal memory of processor in radio module
RFCC1101 and it is de facto part of the hardware.
It can be appropriate to update firmware in some cases (e.g. add a new read device or change of
communication protocol used in reading network).
Warning!

DESCRIPTION PROBLEM INDICATION RECOMMENDED SOLUTION
Collecting unit A can
not establish the radio
contact with control
unit B
Red LED on radio
module of unit A lights
even after restart
The system is designed for remote communication. If
units A and B equipped with antenna are located in
close proximity, receiver is “overload”. Pla e the
olle ting unit A further from ontrol unit B.
Collecting unit A is too far from control unit B or barrier
impermeable for 868 MHz radio waves is located
between them. Pla e olle ting unit A loser to the
ontrol unit B.
Check that DIP switch configuration is the same at both
unit A and B. If not, hange DIP swit h to the same
onfiguration. For more information, see chapter 6.2.
Configuration of multiple overlapping network.
Check that DIP switch configuration is the same at both
unit A and B. If not, hange DIP swit h to the same
onfiguration. For more information, see chapter 6.2.
Configuration of multiple overlapping network.
Check that DIP switch is not in ON ON ON ON
configuration neither at unit A not unit B. This layout is
reserved for test mode and must not be used. If
onfiguration ON-ON-ON-ON is used, hange it. For
more information, see chapter 6.2. Configuration of
multiple overlapping network.
Check that the B unit works correctly.
Connection of
collecting unit A and
control unit B is
unstable
Red LED blinks
irregularly at unit A
Connection is unstable if units are close to their limits
(too far or too close). Solve it as described above.
Pla e olle ting unit A loser (or further) to ontrol
unit B.
Red LED blinks
regularly at unit A
Power supply is not sufficient. It can be caused by weak
batteries or by power supply failure (unit is switched on
but restarted when tried to transmit). Change the
batteries or he k the onne tion to ele tri al
network.
Collecting unit A or
control unit B does not
work
Both LED on radio
module are switched off
even after disconnecting
and connecting of power
supply
Power supply malfunction. Battery voltage must be at
least 2,2 V. Change the batteries or he k the
onne tion to ele tri al network.
Unit malfunction. Send it to manufa turer to repair.
Control unit does not
contain any data from
read devices
There are no data on
the main page
Verify that red LED is off in units A (units are connected)
and green LED blinks in irregular interval of minutes
(data receiving indication). If the unit A does not receive
any data, there are displayed no data at unit B.
Check that unit A is not connected to another reading
network (see chapter 6.2. Configuration of multiple
overlapping network).
