Note:
Units A are equipped with battery supply for the installation purposes (finding the ideal location and
coverage verification). Battery supply is only intended for installation and once the installation is
finished, it should be connected to the mains. The time required for coverage verification may be
different in each object and cannot be calculated in advanced.
Note:
Before the installation of the A units, please check that the DIP switch is set the same on the B unit
and all A units in one reading network (see Picture 4: Schematics of the radio module RFCC1101)
For more information, please check chapter 6.2. Configuration of multiple overlapping networks.

INISHING
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.
