Description of functions
Rocker
The function rocker is to be used if push-buttons are connected to the binary input. Depending
on whether a push-button or rocker is used, this must be set in "Devices, scenes and groups" in
the System Access Point. There select the corresponding binary input to then combine two
channels for the connection of a rocker under "Settings - channel selection".
Notice
Channels can only be coupled as long as they have not been allocated to other
ABB-free@home
Switching of (light) electric circuits
If the rocker function is used in connection with a switch actuator for switching a lamp, for
example, the "Control element" function is to be selected. When connecting a rocker to binary
input BI-F-2.0.x2, the rocker connected to channel A (binary input) activates the channel
allocated to the switch actuator, and the rocker connected to channel B (binary input)
deactivates the channel allocated to the switch actuator. This equally applies to channel
coupling A+B or C+D of 4gang binary input BI-F-4.0.x2 or BI-M-4.0.x.
Switching and dimming of lamps
If a single or double push-button connected to a binary input is to be used together with a
dimmer to dim a lamp, the "Dimming sensor" function is to be selected for the binary input. For a
single push-button, dimming brighter or darker is carried out with an alternating long press of
the push-button rocker. A brief press switches the lamp on or off. With a double push-button the
long press of the rocker(s) connected to channel (coupling channels A+B for BI-F-2.0.x2) or
channels A and C (coupling A+B and C+D for BI-F-4.0.x2) causes the light to become brighter.
A brief press is used to switch the lamp to be dimmed on. Dimming darker is carried out with a
long press of the rocker(s) connected to channel B (BI-F-2.0.x2) or channels B and D (for BI-F-
4.0.x2 or BI-M-4.0.x). A brief press of these rockers is used to switch the lamp to be dimmed off
(compare the previous section).
Operating blinds
The operation of blinds can be carried out via single or double push-buttons. When using a
single push-button, long button actuations lead alternately to an upward or downward
movement of the blind, the roller blind or the awning. A brief press of the push-button during a
movement leads to a stop. After a movement has been stopped, further brief presses of the
push-button cause the slats to be adjusted opposite to the direction of the previous movement.
When using double push-buttons, a long press of the rocker(s) connected to channel A
(coupling of channels A+B for (BI-F-2.0.x2) or channels A and C (coupling A+B and C+D for (BI-
F-4.0.x2 or BI-M-4.0.x) causes the blind(s) to move up, and a brief press to a stop and the
upward movement of the slats. The downward movement or adjustment of the slats in a
downward direction is carried out analogous with the rocker(s) connected to channel B (BI-F-
2.0.x2) or to cannels B and D (for BI-F-4.0.x2 or BI-M-4.0.x).
