1. A GENERAL DESCRIPTION OF THE SENSOR CEN-
TRE STATION
The COMPUTHERM S100 Wi-Fi sensor centre is able to provide continu-
ous information on environmental data (air temperature, humidity, noise
level, luminous intensity) at the place of installation via the Internet, and,
based on measured and set values, is able to control the paired COM-
PUTHERM S200 socket and/or S300 thermostat via a Wi-Fi network.
The apparatus can easily be connected to a Wi-Fi network and paired
with a COMPUTHERM S200 and/or S300 device by means of a smart-
phone. Naturally, environmental parameters can be monitored and set-
tings can be modied by a smartphone.
We o󰀨er the installation of the COMPUTHERM S100 Wi-Fi sensor cen-
tre to those who wish to monitor environmental parameters at the place
of installation and to control their COMPUTHERM S200 socket and/or
S300 thermostat based on the temperature/humidity measured in an-
other room via wireless means. For example, with the installation of the
COMPUTHERM S100 Wi-Fi sensor centre a boiler connected to a COM-
PUTHERM S200 socket in the basement of a house can be easily con-
trolled by the temperature measured in the sitting room upstairs or freez-

5. USE OF THE SENSOR CENTRE AND APPLICATION,
A DESCRIPTION OF FUNCTIONS AND SERVICES
Once you have successfully established a connection between the sen-
sor centre and the Wi-Fi network selected (which must have the Internet
access) and connected the sensor centre to your user account, you can
check the sensor informations freely from a distance via the mobile ap-
plication.
To reach the device log into your user account in the application with your
user name (phone number/e-mail address) and your password. By means
of the menu items that can be opened at the top of the main screen of the
application you can arrange the devices into groups („Group”) then you can
select those you wish to see together on the main screen.
The settings of the user account and the application can be modied and
the application can be updated in settings menu. You can return to the
main menu with the icon showing four squares .
The Andoid application has a widget functionality, with which the basic func-

- 14 -
tionalities of the devices connected to the user account can be accessed
directly from the home screen of the Android device.
The sensor centre will continue its pre-set function even in the absence of
the Internet access. Besides, it will continue its pre-set function after the
power is restored following a mains supply failure (power outage), except
if the Internet is not accessible any longer when power supply is restored.
If, for any reasons, in the future you intend to use you apparatus through
another Wi-Fi network or from another user account then rst you have
to remove it from this account with “Delete” or using the icon then put
the sensor centre into service again by means of the steps described in
Chapter 4.
Attention! In the setting menu of the device the software of the sensor
centre can also be updated. For proper operation please check regularly
whether a software update is available and always use the latest version!
The sensor centre has the following functions and services:
a) Manual ON/OFF control with the help of the switch located on the
power supply cable of the apparatus.
b) The apparatus can be set by pressing „...” then „Setting” button.
Now you can change the name of the apparatus and update the

- 15 -
software. To ensure proper operation check regularly whether any
software update is available and always use the latest version!
c) Usage of the “Share” function
You can share the device with other user accounts (e.g. those of
family members/colleagues) by tapping the „Share” button. Shar-
ing requires that the other party also registers a user account,
enters into this account and stays online while sharing steps are
carried out.
d) Coordinated control of several devices with function „Scene”:
Coordinated control of the devices connected to your user account
can be done with function „Scene”. You can manually control sev-
eral devices simultaneously or, based on pre-set parameters,
turn on/o󰀨 one or more COMPUTHERM Wi-Fi devices that are not
equipped with temperature sensor (e.g. COMPUTHERM S200 Wi-
Fi sockets) with the help of the COMPUTHERM S300 Wi-Fi ther-
mostat as a master device.
The „Scene” function is accessible from the main screen of the
application by tapping icon „...” then menu item „Scene”. After en-
tering into this function you can create a new switch command by
tapping the „+” button at the bottom of the screen, and previous
settings also appear on this screen.

- 16 -
The creation of the switch command is composed of four steps:
1. A name should be given to the switch command (e.g. Turn on the heat-
ing or Turn o󰀨 the heating)
2. After tapping the „+” button located beside menu item „When it meets”
you have to select the type of the switch command: manual start-up
(„Tap to run”) or control from the master device („Master device”).
3. When „Master device” control is chosen, the program o󰀨ers the
device(s) connected to the user account (e.g. the COMPUTHERM S100
Wi-Fi sensor centre), out of which one should be chosen to be a mas-
ter device. Then out of the parameters o󰀨ered for control you have to
choose the one (e.g. temperature) based on which you intend to con-
trol the other device (e.g. a COMPUTHERM S200 socket). Finally, you
have to give the condition belonging to the parameter (e.g. „≤ 21 °C” or
„≥ 22 °C”) then tap the „OK” button to conrm the settings.
4. After conrming the parameters having been set, by tapping the „+”
button located beside menu item (Execute) you can choose the type
of switch („ON” or „OFF”) to be performed when the pre-set value is
reached on the selected device(s) (e.g. a COMPUTHERM S200 socket).

- 17 -
Attention!
Function „Scene” is only in operation when each of the two or more devices
connected to the function have the Internet access.
The active „Scene” function overwrites the manual switch commands therefore
you have to delete or modify the settings of the „Scene” function if you wish
to control, either on the spot or remotely, e.g. a COMPUTHERM S200 socket
controlled by the „Scene” function from a COMPUTHERM S100 sensor centre.
6. PRACTICAL ADVICES
Problems with the Wi-Fi connection
If you are not able to control the device through the Internet because it cannot be
reached through the application, then the connection between the device and the
server has been broken. This can have multiple reasons.
In most of the cases it is caused by the Wi-Fi router. It is practical to restart the
routers from time to time by disconnecting them from the mains voltage for 2
minutes. In most cases the problems can be xed by this. If the devices still
cannot be controlled after a couple of seconds, then you should try to reconnect
the device to the Wi-Fi network, as described in Section 4.2. If you nished the
connecting steps successfully but the device still cannot be controlled, then you

- 18 -
should reset the router to the factory default settings, because it is possible that
some settings of the router do not allow the device to connect to the internet.
The use of the application
The phone/tablet application is under constant development. It is advised to up-
date it to the latest version, as the user experience is continuously enhanced and
there can be new functionalities available in the new versions.
