LK Webserver
Design
LK Webserver is used to access and control
LK Room Temperature Control ICS.2 and/or
LK Water Safety System WSS via the Internet or
a local network. The interface is suitable for cell
phones, tablets or computers and can be reached
via a website or an app for Android and Apple
IOS. Interface updates continually take place and
new functions will be available, see the latest
manual at www.lksystems.se/en.
LK Webserver continually logs the oor heating
system (temperatures, heat to/from etc.) to
enable optimization of the performance of the
oor heating systems. The logged data can be
retrieved and analyzed with LK Analyzer ICS.2
software which can be downloaded from the
LK Systems website.
Installation of the LK Webserver
The webserver can only be connected to the
LK Receiver 8 ICS.2 and LK Water Safety System
WSS. The webserver is placed near a room tem-
perature control if it is to be used for both oor
heating and water safety system. Otherwise it can
be located near a network socket and then com-
municate wirelessly with the master unit of the
water safety system.
The webserver can be installed in three differ-
ent ways:
1 Only for an LK Receiver 8 ICS.2, start the
installation at point 1 in the instructions below.
2 Using two webservers to create a wireless
bridge when an internet connection is not avail-
able near the receiver of the oor heating instal-
lation. Begin installation as shown below in
point 1 in the instructions.
3 Only for the LK Water Safety System WSS,
begin installation as shown below in point 11 in
the instructions.
1 Connecting the LK Receiver 8 ICS.2 with
LK Webserver
An example of a system with the webserver connected by cable
to the router. The webserver is connected to both the water safety
system and room temperature control ICS.2.
1. Attach the webserver with a suitable screw.
2. Switch off the power to the LK Receiver.
3. Connection is done with a three-conductor
cable (> 0.25 mm2). Connect the LK Receiver
8 ICS.2 (Master) three-pole busbar marked-
BUS with cable to the three-pole connection
of the LK Webserver marked BUS ICS.2.
Connect pole to pole, i.e. plus [+] is connect-
ed to plus [+], minus [-] to minus [-] and zero
[0] to zero [0].
BUS cable
4. Energize the LK Receiver.
5. Connect the cable from the mains adapter to
the input Power 5 V DC input on the web-
server, connect the mains adapter to a wall
socket.
6. Connect the network cable between the
webserver’s ethernet-connection and a
network socket with internet access.

2 Connecting the communication bridge
via two webservers
It is possible to create a wireless communi-
cation bridge between the receiver of the
oor heating installation and a network
socket with internet access.
An example of a system with a webserver as a communication
bridge. The webserver is connected to both the water safety sys-
tem and room temperature control ICS.2.
7. Mount the other webserver near a network
socket.
8. Connect the cable from the mains adapter to
the input Power 5 V DC input on the web-
server, connect the mains adapter to a wall
socket.
9. Connect the network cable between the
webserver’s ethernet-connection and a net-
work socket with internet access.
10. On the webserver connected to the receiver,
press and release the red button. The LED
lamp will begin to blink.
Within three minutes, press and release the
red button on the webserver connected to a
network socket.
Thecommunication bridge settings are done
in the tab Network in the webserver’s user
interface, channel 6 is normally used.
3Connecting LK Master Unit WSS with
LK Webserver
11. The LK Master unit WSS communicates
wirelessly with the webserver connected to
the network socket with internet access.
12. Connect the cable from the mains adapter to
the input Power 5 V DC input on the web-
server, connect the mains adapter to a wall
socket.
13. Connect the network cable between the
webserver’s ethernet-connection and a net-
work socket with internet access.
14. Programming the webserver is carried out
by simultaneously pressing the Open and
Timer buttons on the Master Unit for 2
seconds (the radio symbol begins ashing).
After that press and release the red button
on the webserver (the right LED ashes
red). When the connection is established,
the right LED will show a red solid light for
a few seconds.

User interface, functions
LK Webserver makes a simpler and more trans-
parent user interface to adjust system settings
via the room thermostat’s menu and installation
parameters. The LK Webserver always begins
by searching for LK Room Temperature Control
ICS.2. If the webserver is only connected to the
LK Water Safety System, the tab Water can be
clicked on as no room temperature control is
found. The webserver is cloud-based and there
may be updates of the user interface and func-
tions that becomes directly available to the user,
see the latest manual at www.lksystems.se.
