The push-button comfort is plugged onto a flush-mounted
bus coupling unit (flush-mounted BCU). The push-buttons
of the device can be programmed for the following
functions: switching, dimming, blind/shutter control, value
transmitter, light-scene recall, forced guidance and
control. Push-button assignment is free and fixed in the
project.
Depending on the preset functions, a press on any of the
push-buttons sends telegrams to the instabus EIB which
trigger switching, dimming or blind/shutter functions, recall
or store light-scenes and set dimming, brightness or
temperature values in the respective actuators.

Value transmitter: readjustment by long push-button press
If a value transmitter has been parameterized, the value to be transmitted can be readjusted by a long puah-button
press (> 5 s). In this case, the current value is increased by the parameterized interval and transmitted. After
releasing the push-button, the value last transmitted remains stored. During the next long push-button press, the
value is readjusted in the opposite direction.
Depending on parametrization, the status LED shows a different behaviour during value readjustment (see below):

Operating levels
In operating level 1, each push-button can be assigned any of the functions switching / toggle, dimming,
blind/shutter, forced guidance, value transmitter/light-scene extension or control. In operating level 2, the lefthand
and the righthand push-button column is assigned a function from among the push-button functions of operating
level 1.
Operating level 1:
•per push-button one function from among:
switching / toggle, dimming, blind/shutter, forced guidance,
value transmitter/light-scene extension or control
Operating level 2:
•upper push-button colum #4 push-buttons
with the same function
•lower push-button colum#4 push-buttons with the
same function
•function to be selected from the functions of level 1
e.g. 4-gang:
e.g. 4-gang:
Switching-over between operating levels is ensured by a separate object "Operating level". The polarity of this object
can be programmed. In the 4-gang type, switching over can additionally be effected locally on the push-button itself
(see next page).
Operating level 2 can be permanently activated (e.g. switch-back to operating level 1 manually or via object) or, as
an alternative, remain activated for a parameterized time. The switch-over mode is determined by the "Switch-over"
parameter.

Manual switch-over between the two operating levels
The push-button comfort 4-gang can be switched by means of a 3-push-button actuation (push-buttons 1+5+8) and
push-button code between the two operating levels (the "Operating level switch-over" parameter must then be set to
"manual" or "via object and manual").
The operating level switch-over is effected by means of the 3-push-button actuation for approx. 3 s and by entry of
the parameterized push-button code. The following illustration shows manual switching from operating level 1 to
operating level 2. Switching back to operating level 1 is analogous with the first procedure.

Remarks:
•The function of the operation LED (green) for an active operating level 1 is parameterized on parameter card
"General", whereas the function of the operation LED for an active operating level 2 is parameterized on parameter
card "Operating level".
•If the "Switch-over" parameter is set to "Switch-over to level 2 for a time interval", the push-button comfort switches
back automatically to operating level 1 after the preset time.

Push-button-lock by code
This function requires that local disabling of the push-button (4-gang only) has been enabled beforehand in the "Lock
function?" parameter.
The push-buttons are locked by the so-called 3-push-button actuation (push-buttons 2+6+7) for about 3 s and by
entry of the parameterized push-button code. A push-button (when locked) can be unlocked by means of the same
push-button actuation and the current code. The following illustration shows the push-button-lock procedure.

Changing the push-button code
The push-button code is parameterized in the ETS and can be changed in the push-button comfort 4-gang by local
manual operation.
Push-button code change by local operation of the push-button must have been enabled beforehand in the ETS in
the "Local adjustmet of push-button code" parameter.
The push-button code is changed by means of the so-called "3-push-button actuation, i.e. pressing 2+6+7 for at least
8 s followed by the entry of the old push-button code. This is confirmed by all 8 status LEDs flashing at the same
time. The new code can be entered thereafter.
The following illustration shows how to change the push-button code:

"Forced guidance" function
By means of the 2-bit forced-switching object, it is possible, for instance, to force the switching channel of a switching
actuator independent of the switching object into a certain switching position.
The 2-bit telegram controls the states shown in the table below:
Bit 1 Bit 0 Forced guidance Actuator state
0 0 OFF Value of switching object
0 1 OFF Value of switching object
1 0 ON OFF
1 1 ON ON
Bit 1 of the forced guidance object enables forced guidance and bit 0 determines the switching state the actuator is
to adopt. When forced guidance is inactive (bit 1 = 0), bit 0 is irrelevant and the switching channel is controlled by the
switching object of the actuator.

Push-button 1: "Dimming" function parameterized
Function of push-button Operation with two buttons:
brighter (ON)
Operation with two buttons:
darker (OFF)
Operation with one button:
brighter/darker (TOGGLE)
A short push-button-press triggers an ON
telegram, a long push-button-press triggers a
dimming telegram (brighter).
A short push-button-press triggers an OFF
telegram, a long push-button-press triggers a
dimming telegram (darker).
The internally stored is reverted with a short
push-button-press. If the the stored state is
ON (OFF), an OFF (ON) telegram is
triggered. After a long push-button-press, a
"darker" telegram is transmitted after a
"brighter" telegram and vice versa.

DOWN
default: push-buttons 2, 4, 6, 8
TOGGLE
A short push-button-press triggers a STEP
telegram (UP), a long push-button-press
triggers a MOVE telegram (UP).
A short push-button-press triggers a STEP
telegram (DOWN), a long push-button-press
triggers a MOVE telegram (DOWN).
With this setting, the internally stored moving
direction is followed up viathe bus and
switched over after each long-time operation
(MOVE). If a STEP telegram is transmitted by
a short push-button-press, this STEP
command always has the opposite direction
of the last MOVE command. Several
successive STEP telegrams always have the
same direction.

T1
Pressing the push-button sends a STEP and
starts time T1. If the push-button is released
within T1, no further telegram will be
transmitted. This STEP serves the purpose
of stopping a continuous run.
If the push-buttons is held depressed for
longer than T1 a MOVE is transmitted
automatically after the end of T1 and time T2
is started. If the push-button is then released
again within T2, a STEP is transmitted. This
function is used for slat adjustment (T2). T2
should correspond to the time needed for a
slat rotation through 180°.

No adjustment with long push-button-press
possible.
If the push-button is held depressed for at

After releasing of the push-button, the value
last transmitted remains stored. A new long
