Installation of radiator valve
Battery installation
1. Unscrew and pull out the back.
2. Insert the batteries according to the correct polarity. (2 x AA
alkalin batteries, note that you cannot use rechargeable batteries).
3. After inserting the batteries, the current temperature will be
displayed, and the installation symbol will appear.
4. Now screw the cap back on. Make sure that the word TOP on the
back matches the line before screwing it on.

Installation on the heating
First, you must make sure that the radiator knob fits your heating
system. The standard size of thermostatic shut-off valves is
M30 X 1.5. That is the size of the washer of the SF50RV. To find out,
check the brand of your thermostatic valve. You can then look up the
dimensions on the internet. If the radiator knob does not fit your valve,
we recommend that you order an adapter to convert your valve to
M30 x 1.5.
You can use your thermostat button in just a few steps. After the
thermostat has been installed, it will automatically be in manual mode.
1. To install the radiator thermostat on the heater, press the display of
the radiator button for 3 seconds.
2. Finally, a screen containing F11 appears, and the installation light
begins to flicker. At the same time, the thermostat will vibrate
slightly.
3. The thermostat is now ready to be screwed onto the heater. Turn it
with the mounting ring on the heater and make sure that the screen
is turned the right way.
4. Press the radiator thermostat again and F12 will be displayed. After
about 10 seconds, the installation icon will disappear, and the
current temperature will be displayed. The installation is now
complete.

In order to limit the influence of the heat of the heater on the radiator
thermostat, we recommend installing the knob as follows.

Installation on the app
Linking the radiator valve with the app is very simple and takes little
time.
1. First of all, the ELRO Connects 2.0 app must be opened.
2. Tap the "+" in the top right corner.
3. Selet the radiator thermostat.
4. Press the display of the radiator thermostat 3 times in quick
succession. The K2 will let you know once the radiator thermostat
has been installed correctly.
The system is now ready for use. However, it takes between 2 and 8
hours before the system is fully acclimatized. This depends on the size of
the room.

Different modes
The radiator thermostat has 3 different modes: Automatic, Manual and
Antifreeze mode. By pressing once on the display or by adjusting it in the
app, you can switch between the different modes.
Automatic mode
Set timers
1. Tap on the icon of the thermostat in the device list.
2. Click on the clock symbol in the left bottom of the screen.
3. Then you will see an empty list and press +
4. Here you can then set the temperature, time and days for your
timer.
5. You can add as many timers as you like here. Press < to go back.
6. Then press save to save the changed settings.
If the radiator thermostat is in
automatic mode, the radiator
thermostat will automatically jump to
the set temperature. You must set
timers for this in the app. The
temperature will then be adjusted to
your wishes at a selected time. The
routines can therefore be set up
entirely according to your own taste.

-11-
Manual mode
Anti-freeze mode
The temperature will not change
automatically. You can turn the
display yourself to adjust the
temperature. You can also adjust
the temperature in the app.
When the radiator button is in this
mode, it will behave just like a
normal radiator thermostat.
If you are away from home for a
long time, you can switch on
this mode to prevent your pipes
from freezing. You can choose a
temperature between 5-15
degrees.

-12-
Adjust temperature
The temperature can be set in several ways, locally and remotely.
Adjusting temperature locally
When the thermostat is in standby mode, you can adjust the
temperature by turning the knob. Make sure that you press the display
first.
Adjusting temperature in the app
The temperature settings are available in all modes, so you can adjust
them at any time. You can adjust the temperature by using the slider.
1. Press the radiator thermostat in the device list.
2. Pres the cog wheel in the right bottom corner.
3. Select manual or timer mode and adjust the temperature
accordingly.
4. Finally, press the save button. After 10 seconds the settings will be
completely processed.

Functionality
Child lock
The child lock prevents the temperature from being adjusted when the
thermostat knob is turned. When this function is enabled, no settings
can be made via the radiator knob itself. This is to prevent children from
playing with the thermostat. The child lock can be switched on and off
both via the app and via the radiator button itself.
Enabling child lock via the radiator valve
If the radiator valve is pressed for a long time, you can switch the child
safety lock on and off. Please note that the child safety lock can only be
switched on after the installation.
1. Press the button for more than 3 seconds.
2. A padlock icon will appear on the screen to indicate that the
parental control feature is enabled. If you repeat step 1, the parental
control system is deactivated.

-15-
Enable child lock via the app
The child lock can be turned on and off via the app, as shown in the
images below.
1. Select the radiator valve from the device list.
2. Go to settings in the bottom right corner.
3. Select ‘Child lock’ and save your settings

-16-
Open window detection
When this function is enabled, the smart radiator valve will detect when
a window is open. When the temperature drops 3-5 degrees in the
room within 5 to 10 minutes, the radiator valve will stop heating. If this
is the case, the heater will not heat for 30 minutes. After this half hour,
the heating will start again, regardless of whether the window is open or
not. This function can only be switched on and off via the app. This
function prevents heat loss.
You turn on this function by following these steps:
1. Select the radiator valve from the device list.
2. Go to settings in the bottom right corner.
3. Select ‘Open window detection’ and save your settings

-17-
Valve detection
Also called error recognition. When this function is on, errors related to
heating a room will be detected. An error message is given when:
1. Heating the room to the desired temperature takes longer than 2
hours.
2. If the temperature in the room is 2 degrees higher than the set
temperature for more than 1 hour.
3. If the temperature in the room is 3 degrees higher than the set
temperature.
If one of these 3 things happens you will get a notification in the app.
This function is also only controllable from the app.
1. Select the radiator valve in the device list.
2. Go to settings in the bottom right corner.
3. Select “Valve inspection” and save your settings
