CRS 40 V2
Installation, operation and service manual M2019/02a
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.
