7 Start-up
7.1 Simple operator functions using
connected pushbutton
The actuator can be operated immediately using an
external pushbutton (no teach-in required) for checking
that the electrical installation is correct. Existing
pushbuttons can continue to be used.
A short press of the pushbutton switches the load
on and off. A long press of the pushbutton has two
functions:
• If this occurs within the first 5 minutes of
switching on the mains voltage, teach-in mode
is activated.
• If a long pushbutton press occurs after these
5 minutes, dimming takes place. The dimming
direction changes with each pushbutton press.
7.2 Teaching-in
Please read this entire section before starting
the teach-in procedure.
HomeMatic components have to be taught in to each
other in order to communicate.
To execute the teach-in procedure, both of the devices
to be linked must be in teach-in mode.
The actuator does not have a special teach-in button.
To teach in the actuator, connect a suitable voltage-
stable pushbutton to the pushbutton input (see
Installation section). To teach in the actuator, press
and hold down the pushbutton for about 4 seconds
within the first 5 minutes of switching on the mains
voltage.
