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. I
NSTALLATION
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 ceiling) when the power supply is off. Otherwise
the electronic components can be damaged.
Warning!
Before plugging in the charging cord to microprocessor, make sure to plug in backup 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.
