► The wireless actuator is now ready for the "teach in" process.
NOTE
The "push rod" (see illustr. above) may be extended before installation - for instance
if the actuator has been mounted onto a radiator before.
The installation position can be restored ("push rod" retracted) by pressing the
"teach in"/adjustment button for at least 2 seconds. The info LED will flash green
quickly five times after this "adjustment run".
Press the "teach in"/adjustment button for at least 2 seconds before removing the
actuator so that the "push rod" is retracted.
