alkalin batteries, note that you cannot use rechargeable batteries).

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.
