LK Webserver ICS.2
Design
LK Webserver ICS.2 is used to access and control
LK Room Temperature Control ICS.2 from your
mobile phone, tablet or computer. An intuitive
interface makes it easy to monitor, manage and
control all the functions of the underoor heating
system.
All control operations are made using standard
websites, which means that the system works
with virtually all the current market systems
such as smartphones, tablets or computers with
associated operating systems and web browsers
such as, Android, iPhone, iPad, Windows Phone,
Windows PC, Mac, Linux, Firefox, Safari, Internet
Explorer, and others.
LK Webserver ICS.2 continuously logs the under-
oor heating system (temperature, heat on/off,
etc.) making it possible to optimise system per-
formance. The logs can be collected and analysed
using the LK Analyzer ICS.2 software which you
can download from LK System's website.
Initial start-up/installation of the web server typ-
ically requires a PC with the Windows OS, read
more in the instructions below.
LK Webserver ICS.2 connects to the LK Receiver
8 ICS.2.
User interface, functions
LK Webserver ICS.2 provides a simpler and more
transparent user interface than if you make sys-
tem settings via the room thermostat menu and
setting parameters.
Menu tab Thermostats
The Thermostats tab gives you an overview of the
system's receivers and the connected room ther-
mostats. The names of thermostats and receivers
can be changed to names of your choice, by way
of suggestion use the room name/room number.

Connection – with access from the local network
System example with the web server cable connected to the router.
Several LK Receivers ICS.2 can communicate in the system. The
web server is connected to the master receiver. Other receivers
become slaves and communicate wirelessly with the master unit.
1. Connections are made using a three-core
cable (min cable area 0.25 mm²) from LK
Receiver 8 ICS.2 three-pole bus connector
marked BUS to LK Webserver ICS.2's three-
pole connector marked BUS ICS.2. Connect
pole to pole i.e. to ensure that plus [+] is
connected to plus [+], minus [-] to minus [-]
and zero [0] to [0].
In a system with multiple receivers (max. 8 pcs.)
these are installed in your own network with
wireless communication between the devices.
All shared information is communicated to the
system's master unit. LK Webserver ICS.2 is
connected to the master unit. Keep in mind
that only LK's 8-channel receiver LK Receiver
8 ICS.2 can be a master unit. In an installation
with multiple receivers, an optional receiver is
selected as the master. Read more about this in
the manual for the LK Room Temperature Con-
trol ICS.2. If possible, select the receiver that is
closest to the building's Internet connection as
the master unit.
In a system with only one LK Receiver 8 ICS.2,
this represents the master unit.
2. Connect a standard network cable (CAT 5) be-
tween the web server's Ethernet connector and
any available LAN port at the router/modem.
3. Connect the power adapter to a 230V AC
wall outlet and its power cable to the web
server's Power 5V DC input.
4. Connect a PC with Windows to your local
network.
Initial start-up requires a PC with Windows.
After completion of the installation, any computer,
smartphone or tablet with any operating system can
be used to control the system.
5. Enter the address that is pre-printed on the
web server that is connected to the router,
see image below. In this case, http://af301.
A dialog box will then appear. Enter Us-
ername and Password here. Username and
Password are pre-printed on the web server.

6. Once the program is open, select the
Network tab.
7. Note the addresses under the heading
How to connect.
You can use these addresses to connect to the web
server via the Internet or locally. There are now
two addresses to choose from for a local connec-
tion. The shorter address can only be used on PCs
with the Windows operating system.
Bear in mind that the Internet address needs time
to be registered online. It can take up to 72 hours
before the address is registered, but this is nor-
mally signicantly faster.

Connection with a communication bridge
– with access from local network
System example with two web servers that communicate wirelessly
between each other where one is tasked to serve as a communication
bridge. Several LK Receivers ICS.2 may be installed in the system.
The web server is connected to the master receiver. Other receivers
become slaves and communicate wirelessly with the master unit.
LK Webserver ICS.2 can also be used as a wireless
communications bridge. This wireless communi-
cations bridge function is used when the Internet
is unavailable in the property at the underoor
heating installation's receiver. A wireless commu-
nication can then be established between two LK
Webservers ICS.2. The rst web server is installed
at the underoor heating installation's receiver
and the other at the building's Internet connection.
The web server located at the receiver will now
operate as a wireless communications bridge to
the web server with an Internet connection.
Connection and learning are carried out according
to the specifications below:
Connection:
1. Connections are made using a three-core
cable (min cable area 0.25 mm2) from LK
Receiver 8 ICS.2 three-pole bus connector
marked BUS to LK Webserver ICS.2's three-
pole connector marked BUS ICS.2. Connect
pole to pole i.e. to ensure that plus [+] is
connected to plus [+], minus [-] to minus [-]
and zero [0] to [0]. This unit will now oper-
ate as a wireless communications bridge in
relation to the other web server that is to be
located at the property's router/modem.
2. Connect the power adapter to a 230V AC
wall outlet and its power cable to the Web
server's Power 5 V DC input.
3. Connect the other web server to the proper-
ty's router/modem. Use a standard network
cable between the web server's Ethernet
connector and any available LAN port at
the router/modem.
4. Connect the power adapter to a 230V AC
wall outlet and its power cable to the web
server's Power input 5 V DC.
Establish wireless communication between the
web server units:
1. Connect a PC with Windows to your local
network.
Initial start-up requires a PC with Windows. After
completion of the installation, any computer, smart-
phone or tablet with any operating system can be
used to control the system.
2. Enter the address that is pre-printed on the
web server that is connected to the router,
see image below. In this case, http://af301. A
dialog box will now appear where you enter

6. On the web server no. 2 that is connected
to the receiver, press and release the red
button. The LED light starts ashing.
7. Within three minutes, press and release the
red button on web server no. 1 that is connect-
ed to the router/modem. The connection is
established and the LED lamps stop ashing.
8. Reload the program page on your Windows
PC. This is best done by pressing the Net-
work tab once. The program will now tell
you that the wireless connection is estab-
lished. This can now be seen in the Wireless
connection section where at the bottom you
will see that, Wireless connection is ON.
9. Once the wireless communication between the
web server units has been established, proceed
to How to connect under the network tab.
Note the addresses under How to connect.
You can use these addresses to connect to the web
server via the Internet or locally. There are now
two addresses to choose from for a local connec-
tion. The shorter address can only be used on PCs
with the Windows operating system.
Bear in mind that the Internet address needs time
to be registered online. Note that it may take up
to 72 hours before it is registered, but normally
this is a lot quicker.
Access from the Internet, in general
Your web server is factory congured for access
via the Internet by UPnP being enabled and that
port 8080 is the default. This can be seen in the
Network section under the Network tab.
If port 8080 were to be occupied by other equip-
ment, you can select a different port between 1
and 65535.
Under Network the DHCP will normally always
be unchecked. This is the default from the factory.
Access via the Internet requires that your router supports
UPnP and that this function is enabled. It is normal that
UPnP is enabled at the factory, but some routers require
this function to be enabled manually. See the manual for
your specic router or contact the manufacturer/Internet
service provider.
In some exceptional cases, the LK Webserver ICS.2 is
not compatible with the router's UPnP function. In this
case, you must manually open a port that points to the
web server's IP address, port 80. See the manufacturer's
manual/instructions for more details. In principle, the
following steps must be performed:
1. Identify the web server's local IP address by connecting to
the address at the top of the label using a Windows PC. Now
click “Network”, and read the “IP address” under “System
Info”. NOTE: Do not use the “External IP address”.
2. Log into the router and nd “Port forwarding”.
3. Select a port, such as 8080 and set “port forward” from port
8080 to port 80 on the web server's IP address.
4. Save the settings on the router.

Resetting the web server
The web server can be reset to factory settings.
A reset will clear any specied passwords, all
names of thermostats and all log data. The pass-
word that appears on the web server's label will
then apply. The web server can be reset as follows.
• Unplug the power cord to the device.
• Hold the red button Reset/Mating in.
• Reconnect the power cord but continue to hold
the red button in.
• Release the red button after 10 seconds.
Dynamic DNS
Private individuals are normally assigned a dy-
namic IP number from their Internet service
provider. You need to know this IP number in
order to reach LK Webserver ICS.2 over the inter-
net. The IP number can sometimes change, this
may happen especially if you disable your rout-
er for a while. To make it easier to access your
web server, LK Systems provides a free service
called Dynamic DNS, which makes it possible
to reach the web server via a URL instead of an
IP address. This address is written on the second
line of the web server's label (e.g. http://af301.
lkics.net:8080). LK Systems will provide this ser-
vice for around ve years from the date of man-
ufacture of LK Webserver ICS.2. However, when
the service has ended, you can still reach the web
server, but in this case via the external IP-address
(e.g. http://123.456.789.123:8080). The external
IP address to be used can be found at the bottom
of the Networktab.
Password
It is possible to change the password from your
pre-set one to a password of your choice.
Please note, be sure to choose a strong password
preferably containing a combination of upper-
case and lowercase letters and numbers.
If the web server is reset to the factory default, the
password will return to the original one given to
the device.
