Adaptation
Initial installation: press the button

The device will adapt itself to the stroke of your valve body.
To do this the valve will now be opened and closed several times to store
the end points.
In some cases this process can take a few minutes.
After successful adaptation it returns to normal mode.
Should adaptation become necessary again, e.g. if your radiator does
not cool down in the position, please press in the menu the button
ADAP until adaptation starts again.
If the mistake E2 is shown on the display place K470H onto the radiator
valve and then take the batteries out for a short time in order to execute
a reset.
