Product description
The RCU consists of a communications module, a GSM
modem with an antenna (only RCU 10) and a separate
power supply unit with jack for plugging into a wall socket.
The antenna can be placed outside the enclosure.
It is possible to connect to the RCU two independent
switch functions to detect external events such as a move-
ment alarm or freezing protection.
Note that all configuration of the unit requires that a com-
puter with support for ”JAVA-applets” is connected, even
if only text messaging is going to be used.
Only RCU 10
The RCU enables operations to be controlled and moni-
tored using a computer connected to a local network or
via the Internet. The integrated GSM module also enables
control and monitoring by sending text messages from a
mobile phone. For the GSM function to work, the commu-
nications module must be equipped with a valid GSM sub-
scription. This may for example be a cash card or a special
telematics subscription.
If a SIM card is used, it must be configured
so that a PIN code is not used to obtain
connection. This can be done in a mobile
telephone or by the service provider.
NOTE!

Quick start guide
Double click on the line with your RCU in the
Netbiter window. A new window opens.
The RCU is connected to a local network:
Enter the network settings that apply to your net-
work. To obtain the necessary information concer-
ning your network settings, please contact your
network administrator.
The RCU is directly connected to the computer:
Enter the first three values from your computer’s IP
address, for example, 10.1.1. The fourth is set to
a value other than the one used in computer’s IP
address.
Example:
If the computer has the IP address 10.1.1.1 then set
the RCU address to 10.1.1.X, where X can be set
to any number between 2 and 254 (not 1, as this is
used by the computer in this example).
Complete setting by giving a valid password and
press ”Set”. The factory-set password is ”admin”.
Write down the password and keep it in a safe pla-
ce. If the password is lost the RCU must be returned

General
The RCU has a preset IP address: 10.200.1.1.
NOTE! Images and settings on the following pages may
show some difference, depending on the browser, settings
and the version of the RCU, as well as the heat pump con-
figuration.
RCU configuration software
The RCU configuration software is a PC-based program
that can be used to prepare different networkparameters
in the RCU. The program can search for RCU units on an
Ethernet network, after which the IP address, network
mask, gateway, DNS, etc. can be set. DHCP can also be
activated in the unit.
Install by running the installation program Setup-
NetBiterConfig.exe that is on the supplied CD.
System requirements
Pentium 133 MHz•
5 MB free hard disk space•
Windows 95/98/ME/NT/2000/XP•
Network card (Ethernet)•
If a different operating system than Windows is used the
configuration software can not be used. Then connect to
the RCU’s preset IP address in the web browser and use the
web interface to change the network settings. See section
“Starting” – “Logging in”.
Search for connected units
When the program starts, it will automatically search for
an RCU network connection. A list will be displayed of all
units that are found. A new search can be made by pres-
sing the “Scan” button.
A DHCP server can be started under Advanced options
(only active when Netbiter Config is running). Use this al-
ternative to find an RCU which is unintentionally set to use
DHCP in a network where DHCP servers are missing.

The preset password is ”admin”.
On pressing the “Set” button the RCU will restart, after
which the new settings will be activated.
The new settings can be tested by opening a browser and
entering the set IP address. If DHCP is activated, a new
search can be made with the program to see which IP add-
ress has been assigned to the RCU-10.
If Dynamic IP addressing is used in the local
network, the DHCP server should be con-
figured so that RCU’s MAC-ID retains the
same IP address each time.
