¼DANGER
Risk of fatal injury from electrical current.
The unit may only be installed and connected by
skilled electicians. Observe the regulations valid
in the country of use, as well as the valid KNX
guidelines.
The push-button plus with room temperature con-
trol unit (reffered to below as the push-button) gives
you four (push-button 2-gang) or eight (push-button 4-
gang) operating surfaces. The keys can be set individu-
ally to perform various functions. Furthermore a room
temperature control unit is integrated, which allows you
to control temperature in various different ways.
Functions of the push-button:
– Switching, toggling, dimming, blind control
– Szenenfunktion
– Communication and disable functions
– Time control with synchronisation, reading external
temperature, fan control
Functions of the room temperature control unit:
– Heating/cooling with 1 controller output
– Heating/cooling with seperated controller outputs
– Heating/cooling with 2 controller outputs
The push-button can directly be connected to the KNX
and is parameterised by the electrical installer via the
KNX-Tool-Software (ETS).

Getting to know the keypad
The push-buttons opposite each other can be config-
ured as either individual push-buttons or a push-button
pair. The push-buttons are programmed with various
functions depending on the pre-setting.
For 4-gang push-button only:
The 4-gang push-button is equipped with an IR receiver,
with which you can control the push-button with any IR
remote control. Pressing push-buttons 1-8 on the remote
control activates the function of the corresponding push-
button. Push-buttons 9 and 10 of the remote control have
a direct effect on display push-buttons 9 and 10.
In order for the integrated room temperature control unit
to work in the best way, you should keep in mind the fol-
lowing when selecting the right installation side:

½CAUTION
The device could become damaged.
Before removing the push-button, check whether
it is secured with protection against theft. Always
remove the protection against theft before remov-
ing the push-button.
Opening the labelling field
Creating labelled foil strips
You can also create and print corresponding foil strip
templates with any layout program.
Size specifications for foils (in mm):
Consult the operating instructions of your printer to find
out which type of foil strips you can print.
|Only use the coloured foil strips enclosed as the
base, since this ensures that the push-button
LEDs under the labelling field can shine through.
|Two versions of coloured foil strips are provided:
one with a recess in the middle for the IR receiver,
and one without a recess. If you want to control
the push-button via an IR remote control, you
have to use the coloured foil strip with recess. Al-
ways only use one of the two coloured foil strips.

When installing the push-button, the electrician defines
various settings that are necessary so you can use the
push-button correctly. Most of the explanations provided
on the following pages depend on these settings. The
electrician enters the settings in question in a table for
you (see table „pre-settings”).
|If you come across this symbol when reading,
it means that you can look up the corresponding
value in the table.
With the integrated room temperature control unit, you
can control the temperature in various different ways.
You can read and set important information on the dis-
play:
• Setpoint temperature
• Operating mode (comfort, standby, night, etc.)
• Working day/holiday
• Display mode (setpoint temperature, actual tempera-
ture, date etc.)
•Backgroundlighting
• Setting the time/switching time
Getting to know the display
You will see the following symbols on the display:
Pre-settings

Getting to know the control menu
There is a control menu for selecting the individual func-
tions of the room temperature controller.
A rocker is integrated in the cover of the display. It has
three contacts: left, centre and right. With these push-
buttons, you can access the control menu, scroll back-
wards and forwards and change individual values.
Overview of the menu structure
*Long push-button action = approx. 5 s
**Short push-button action = approx. 1 s
|If you don‘t press any push-button within a period
of about one minute, the room temperature con-
trol unit automatically returns to the standard dis-
play. The values that were set before the control
menu was opened are restored; any changes
that you may have made are not saved. Ex-
ception: The temperature is saved directly.

Standard display
Here you see an example of the standard display:
• „Comfort“ operating mode
• Actual temperature
• Heating is active in order to reach the comfort set-
point temperature .
• is constantly displayed: The time has been syn-
chronised with the time switch (e.g. year time switch
REG-K). Clock symbol flashes: The time has not (yet)
been synchronised.
•Weekdaydisplay3= Wednesday
|Note that the display of the weekday depends on
the pre-settings. The electrician has set ,
a specific weekday to 1. In some countries the
first day of the week is not Monday, but Sunday,
for example. The other numbers have different
meanings accordingly (e.g., 2 = Monday,
3 = Tuesday etc.).
Setting the setpoint temperature
The electrician has specified three setpoint tempera-
tures ( for both heating and cooling):
• for comfort mode
• for standby mode
• for night operation
|You see the setpoint temperature of the current
operating mode. You can only change this set-
point temperature. In order to change the setpoint
temperature of another operating mode, you first
have to switch the operating mode (see „Setting
the operating mode“).
|The electrician specified , within which limits
this value can be changed (for example, within a
minimum of 16 °C up to a maximum of 26 °C). You
cannot set any value below or above these limit
values. If the electrician made the appropriate
setting , the 4-gang push-button emits a warn-
ing sound as soon as you attempt to exceed
these limit values.

number of group addresses and assignments: 254 ad-
dresses, 255 connections
Notes on this documentation
This application enables you to implement a multitude
of functions with the push-button. However, which func-
tions are possible in each individual case depends on
the KNX devices being controlled (e.g. dimming actua-
tors, switch actuators etc.). The functions described
here therefore show only the settings for this push-but-
ton.
|Many parameters and their settings are depend-
ent on the settings you have already made for oth-
er parameters. This means that some parameters
will appear or disappear and the values available
for selection will change according to settings you
have already made. These dependencies have
not been shown in the table for reasons of clarity.
All settings are always shown.
|Configurable times (staircase timer, ON delay,
OFF delay, cyclic intervals etc.) are set via the
base and factor parameters. The actual time is giv-
en by the multiplication of the two values. Exam-
ple: Base = 1 second * factor = 3 gives 3 seconds.
|The bold values in a table are the values set dur-
ing factory configuration.
Before you start, specify certain basic settings on the
"General" tab. You can specify the following:
• Whether the operational LED switches off or displays
that the device is operating.
• Whether a push-button emits a sound when activated.
• Which remote control IR range (infrared range) the
push-buttons react to.
• How the date and time are received.
• Whether and how the time is sent cyclically to the bus.
• How long the push-button's start-up delay should be
after bus voltage recovery.
General settings for date and time
Here you set whether the date and time are received by
two communication objects (3 byte each) or by only one
communication object. In the latter case, there is an
8byteobjectavailable.
If you send the time cyclically to the bus, you either have
an output object with 3 byte or one with 8 byte, depend-
ing on which format you selected.
For further details about time control, synchronisation
and the master-slave function, see the "Time control"
chapter.

Setting the display
Start-up delay
The start-up delay is the time delay between the bus
voltage recovery and the device's functional start. Set a
time after which the current values can be read by other
KNX devices.
Communication objects
You can select the following communication objects:
Here, you set the display options and display functions:
• You can disable the control menu so that the menu
buttons cannot be used to make further changes to
the settings.
• You use the display mode to specify which values you
want to display on the basic display (actual tempera-
ture, setpoint temperature, time, date, external tem-
perature and fan speed). You can display these
values either individually or in alternation. You can
also set the display rhythm for alternating displays.
The display mode can also be set using the control
menu on the push-button.
• For the weekday display, you can set day "1". This
means that the first weekday can be defined as: Fri-
day, Saturday, Sunday or Monday. Each weekday is
then shown in the display with a different number ac-
cordingly.
• Time format and unit of temperature display (Celsius/
Fahrenheit).
• The background lighting on the display can either be
switched off or on at all times, or can be switched on
during operation. You can also set the persistence pe-
riod and the brightness of the background lighting.
|The parameters for the background illumination
and display mode can be changed using the menu
buttons on the push-button (see operating instruc-
tions).
If you use room temperature control ("Control general"
tab), additional possible settings appear:
• You can specify whether or not the operation mode
can be changed when the frost or heat protection op-
eration mode is activated.
• "Access menu setpoint temperature/operation mode
directly" Here, you specify which operation mode you
want to select with a short push of a button on the
menu buttons. You can choose between the control
menu "Set setpoint temperature" or "Set operation
mode".
• On the display, a symbol can show either the current
controller status or whether heating or cooling is acti-
vated.

Use signal function
The signal function enables the push-button to display
various states to you by means of:
• The bell symbol in the display
• Flashing status LEDs or
• Acoustically
The following states can be displayed:
• The specified limits for setpoint adjustment have not
been reached or have been exceeded.
• The preconfigured value of the actual temperature
has not been reached or has been exceeded.
The acoustic signalling ends after a parameterised time
(1 to 254 seconds) or once the actual temperature is
back within the set range.
When a signal is issued, a "1" is transmitted to the bus
via the "Feedback object output", and a "0" is transmit-
ted at the end. The "Feedback object input" can (for ex-
ample) be set to "1" by another sensor and the push-
button reacts as parameterised.
|With the setting "Acoustic signal stops - after a pa-
rameterised time", the acoustic signal only sounds
for the parameterised duration. However, the visu-
al display continues until the signal ends. You can
acknowledge the signal by pressing a menu but-
ton. It is also possible to acknowledge the signal if
an alarm is triggered via the feedback object.
|With the setting "Acoustic signal stops - if actual
temp. is within limits again", the signal cannot be
acknowledged. The acoustic and visual signalling
remain until the actual temperature is back within
the parameterised limits. It is not possible to ac-
knowledge the signal when the alarm is triggered
via the feedback object.

Push-button information
Communication objects
You can select the following communication objects:
On the “Push-button info” tab you can see which push-
button names in ETS correspond to which push-but-
tons on the device. The names assigned cannot be
changed.
Each time the button is pressed, the 1-bit object type
first inverts the object value and then transmits it to the
bus, in other words making a “0” into a “1”. If the same
button is pressed again, the “1” turns back into a “0”.
The device is thus switched on and off alternately. This
switching behaviour is called “toggling”.
For 1-byte object types, you can set two values, which
are transmitted alternately after each press of the but-
ton.
An update or change to the object values is possible via
the bus when another sensor switches the actuator
(e.g. via a two-way circuit or a central command). To
prevent “incorrect” toggling, the state of the actuator
(“1” or “0”) must be tracked in the push-button. To do
this, connect the group address of the second sensor to
the switch/value object of the push-button.
Two objects (1 bit / 1 byte) can also be transmitted in
any combination when the push-button is pressed.
Status indication
The status LED can:
• Be switched on or off continuously.
• Light up when pressed (for a long period), and go out
when released.
•Flash.
• Display the status of the switch/value object. When
the 1 byte object type is used, the LED lights up if val-
ue 1 is greater than zero.
• Display the status of the status feedback object.

Dimming
Communication objects
You can select the following communication objects: You can use the dimming function for the following:
• Dim brighter and darker using one push-button (sin-
gle-button dimming)
• Either dim brighter or darker. You need a second
push-button to dim in the other direction (two-button
dimming).
Status indication
The status LED can:
• Display the status of the switch object
• Light up when pressed (for a long period), and go out
when released
• Be on or off continuously
•Flash
• Display the status of the status feedback object
Common parameters for single-button and two-
button dimming
You can use the corresponding push-button to switch
the light on or off (brief press) or dim it (longer press, the
exact period can be parameterised). When switching
takes place, an ON/OFF telegram is sent via the switch
object. When dimming, dimming up or dimming down is
carried out via the 4-bit dimming object; the parameters
for the dimming steps can be set. You can also transmit
the relevant dimming step cyclically for a period of time
which can be set as required.

Dimming
Single-button dimming
You can dim both lighter and darker and also switch
both on and off using a single push-button.
The current switching or dimming direction is always
dependent on the previous action, i.e. if switched off, a
brief push of the button will switch the light on and vice
versa, and if the light has been dimmed up, prolonged
operation of the push-button will dim the light down
again. On release after prolonged actuation, a stop tel-
egram will be transmitted via the 4-bit dimming object,
thus terminating the dimming procedure in the dimming
actuator.
An update or change to the object value is possible via
the bus when another sensor switches or dims the ac-
tuator (e.g. via a two-way circuit or a central command).
To prevent “incorrect” switching/dimming activity, the
state of the actuator must be tracked in the push-button.
To do this, connect the group address of the second
sensor to the switch/dimming object of the push-button.
A single command is sufficient to cycle through the dim-
ming range. This dimming procedure can be used for
most applications. The other possible dimming steps
(1/2 - 1/64 brighter or darker) dim brighter or darker by
the selected step. For example, if the step is set to 1/4,
you would need to push the button for a prolonged pe-
riod four times in succession to dim from minimum to
maximum brightness.
Two-button dimming
You can dim either lighter or darker and switch either on
or off with a single push-button. A second push-button
for the opposite direction must be parameterised.
You can specify whether a stop telegram is to be trans-
mitted when the push-button is released. If you have
enabled the transmission of a stop telegram, a stop tel-
egram will be transmitted via the 4-bit dimming object
when the push-button is released after prolonged actu-
ation, thus terminating the dimming procedure in the
dimming actuator.
A single command is sufficient to cycle through the dim-
ming range. This dimming procedure can be used for
most applications. The other possible dimming steps
(1/2 - 1/64 brighter or darker) dim brighter or darker by
the selected step. For example, if the step is set to 1/4,
you would need to push the button for a prolonged pe-
riod four times in succession to dim from minimum to
maximum brightness.

Blind control
You can use the blind control function to do the follow-
ing:
• Raise the blinds/adjust the slats using a single push-
button and lower the blinds/adjust the slats using a
second push-button (two-button blind operation).
• Move the blind using an individual push-button and
adjust the slats (single-button blind operation).
• Move the blind to a pre-specified position.
• Move the blind back and forth between two previously
specified positions.
Status indication
The status LED can:
•Flash
• Light up when pressed, and go out when released
• Be on or off continuously
• Display the status of the status feedback object
Two-button blind operation
You can either raise or lower the blind with a single
push-button.
When the corresponding push-button is pressed for a
short time, a stop/step telegram is transmitted; when
the push-button is pressed for a longer period (the ex-
act period can be parameterised), a movement tele-
gram is transmitted. With this function, you must
parameterise a second push-button with the corre-
sponding settings for blind movement in the opposite
direction. Both push-buttons must be given the same
group addresses.
Single-button blind operation
You can both ra i s e and lower the blind with a single
push-button.
The current direction of movement of the blind, or the
direction of the slat adjustment, always depends on the
previous action, i.e. when the blind has just been low-
ered, it will be raised the next time the push-button is
activated for a long period (the exact period can be pa-
rameterised).
When a stop/step telegram has been transmitted to ad-
just the slats, a stop/step telegram for the same direc-
tion of movement can be generated by pressing the
push-button again, as long as this subsequent push-
button action is carried out within a set time period
(which can be parameterised). If that time period has
elapsed, the direction of rotation of the slats will change
when the push-button is pressed briefly.
The push-button can receive telegrams via the stop/
step and movement object, and can generate corre-
sponding telegrams when the push-button is pressed,
according to the values received. An update or change
to the object values is possible via the bus when anoth-
er sensor switches the actuator (e.g. via a two-way cir-
cuit or a central command). To prevent “incorrect”
movement, the state of the actuator must be tracked in
the push-button. To do this, connect the group address
of the second sensor to the stop/step and movement
object of the push-button.

Moving the blind to a pre-specified position
If the blind actuator is capable of moving to specific po-
sition, you can use this function to specify one or two
positions to which the blind can be moved using 1 byte
position values with a push-button action. The position
values can be set in steps between 0% and 100%, or in-
finitely from 0-255.
When moving to a position, the set value for the blind
position and the slat position is transmitted using a
short (or long) push-button action.
To address two positions, enter the required blind posi-
tion and slat position for both. Position value 1 is trans-
mitted with a short push-button action, while position
value 2 is transmitted with a long push-button action.
No movement or stop/step objects exist with these set
parameters.
Communication objects
You can select the following communication objects:
With this edge function you can transmit one or two ob-
jects simultaneously, and select the size of the objects
required as needed (1 bit, 2 bit priority control, 4 bit or
1 byte in steps or infinitely). A distinction is made be-
tween the normal edge function and the extended edge
function:
• With the normal edge function, you can specify which
actions should be carried out when a push-button is
pressed, and which should be carried out when a
push-button is released.
• With the extended edge function you can also param-
eterise different actions to take place upon short and
long operation of the push-button.

Normal edge function
With the normal edge function, you can specify which
actions should be carried out when a push-button is
pressed, and which should be carried out when a push-
button is released. These actions could include:
• Send 1 or 0 (with 1 bit)
• Send value 1 or value 2 (with 2 bit, 4 bit or 1 byte):
You can enter two values and set whether and how
they are to be transmitted.
• Object sends its value:
The object transmits the value which it currently has.
Therefore you can, for example, transmit a value with
the sending group address which was previously re-
ceived via another group address.
• Toggle:
The current object value is inverted and then transmit-
ted. The device is thus switched on/off alternately or
transmitted value 1/value 2 (toggling). The value can
be modified via the bus.
• No action
The values available to you are 1 bit, 2 bit (priority con-
trol), 4 bit, 1 byte in steps or infinitely.

Principle of the edge function
Using the following diagrams, you can see how the
edge function behaves when edges rise or fall.
The settings for “Action on operation / Action at release”
are shown directly above each diagram.
Extended edge function
With the extended edge function, you have a wider
range of functions available. For example, you can set
different actions for short and long presses of a push-
button, both for when the push-button is pressed and
for when it is released. You can also set a cycle time
which can be parameterised for each object.
|When parameterising, bear in mind that you need
to set all four types of push-button operation
(short/long press, pressing and releasing the but-
ton) in order to ensure that the push-button func-
tions as required.
|In order to read the object values, you may need to
set the Read flags manually.
The following activation sequence chart shows the
phases into which the pulse edge function is divided:

A description of the most important actions is given be-
low:
• Sends [value]:
Transmits the current value and stops a cyclical trans-
mission.
• Sends [value] immediately and then cyclically:
If no cycle time is running, [value] is transmitted imme-
diately and a new cycle time is started. If a cycle time
is already running, it is interrupted, [value] is transmit-
ted and a new cycle time is started.
• Sends [value] only cyclically:
If no cycle time is running, [value] is transmitted imme-
diately and a new cycle time is started. If a cycle time
is already running, it is not interrupted; [value] is
transmitted after the current cycle time has elapsed,
and a new cycle time is started.
• Sets object value to [value] (readable only)
[value] is written into the object and is not transmitted.
Any active cycle time is terminated.
• Toggles:
Compares the current object value with [value]. If both
are the same, value 1 or value 2 is transmitted. If they
are different, [value] is transmitted.
• Toggles, sends immediately, then cyclically:
If no cycle time is running, the value is toggled (see
“toggles”), transmitted immediately, and a new cycle
time is started. If a cycle time is already running, it is
interrupted, the toggled value is transmitted and a
new cycle time is started. Subsequently, the value
which has already been toggled is always transmitted
cyclically.
• Toggles, only sends cyclically:
If no cycle time is running, the toggled value is trans-
mitted immediately and a new cycle time is started. If
a cycle time is already running, it is not interrupted;
the toggled value is transmitted after the current cycle
time has elapsed, and a new cycle time is started.
Subsequently, the value which has already been tog-
gled is always transmitted cyclically.
• Toggles and is not sent:
The toggled value is written into the object and is not
transmitted. Any active cycle time is terminated.
• Toggles cyclically, sends immediately, then cyclically:
If no cycle time is running, the value is toggled (see
“toggles”), transmitted immediately, and a new cycle
time is started. If a cycle time is already running, it is
interrupted, the toggled value is transmitted and a
new cycle time is started. Subsequently, it is always
toggled cyclically and the new value is transmitted.
• Toggles cyclically, only sends cyclically:
If no cycle time is running, the toggled value is trans-
mitted immediately and a new cycle time is started. If
a cycle time is already running, it is not interrupted;
the toggled value is transmitted after the current cycle
time has elapsed, and a new cycle time is started.
Subsequently, it is always toggled cyclically and the
new value is transmitted.
• Toggles cyclically and is not sent:
The toggled value is written into the object and is not
transmitted. Subsequently, it is always toggled cycli-
cally and the new value is written into the object.
• Sends its value:
The current object value is transmitted. Any active cy-
cle time is terminated.
• Sends its value immediately and then cyclically:
If no cycle time is running, the current object value is
transmitted immediately and a new cycle time is start-
ed. If a cycle time is already running, it is interrupted,
the current object value is transmitted and a new cycle
time is started. Subsequently, the current object value
is always transmitted cyclically.
• Cyclically increase the current object value by [value]:
If no cycle time is running, [value] is added to the cur-
rent object value, the object value is transmitted, and
a new cycle time is started. If a cycle time is already
running, it is not interrupted; the current object value
with [value] added is transmitted and a new cycle time
is started.
• Reduce the current object value by [value] cyclically:
If no cycle time is running, [value] is subtracted from
the current object value, the object value is transmit-
ted, and a new cycle time is started. If a cycle time is
already running, it is not interrupted; the current ob-
ject value with [value] subtracted is transmitted and a
new cycle time is started.
• Sends [value A] and after a cycle time [value B]:
[value A] is transmitted immediately, and [value B] is
transmitted after one cycle time, regardless of wheth-
er a cycle time is already running or not (staircase
lighting timer function).
• None (stops cyclical sending):
No action is carried out, and any active cycle time is
stopped.
•Nochange:
The current action remains unchanged (e.g. “sends
value 1, then value 2 after a cycle time”).
• None (stop after current cycle time):
No action is currently carried out, but any active cycle
time is not stopped. It runs through until the end, and
then transmits the corresponding value.

Sending edge commands - 1 bit, 2 bit (priority), 4 bit, 1 byte
Examples of use for the edge function
The following activation sequence chart shows the
phases into which the pulse edge function is divided:
Staircase lighting function with cleaning light
function
With a brief press of a push-button, the switch actuator
switches on the light. A long press of the push-button
extends the staircase lighting function (= cleaning light
function) until a second long press of the button switch-
es off the actuator. The switch actuator requires a stair-
case lighting function and a disable function for this
function.
Short and long staircase timer
You can use this function to produce a brief and a long
staircase lighting time with the push-button. The switch
actuator requires no staircase lighting function for this
request.
With a brief press of the push-button, the switch actua-
tor switches on the light, and after a parameterised cy-
cle time (e.g. 3 minutes), it switches it back off again.
With a long press of the push-button, the same function
is carried out, but with a longer cycle time (e.g. 6 min-
utes).
Number of objects = 2 (object A/B)
Object A/B = 1 bit
Object A: Action on release before the long operating time has
elapsed = Sends 1
Object B: Action on achieving the long operating time = Toggles

object of the switch actuator.

Switching the light on/off permanently, or switch-
ing off after a cycle time has elapsed
With a brief press of a push-button, the switch actuator
switches the light on or off permanently. With a long
press of a push-button, the light switches on, and after
a parameterised cycle time (e.g. 6 minutes), it switches
back off again. Due to the cycle time in the push-button
which can be parameterised, the switch actuator re-
quires no staircase lighting function for this function.
Electronic protection against theft
This example will show you how to program electronic
theft protection for the push-button. It is activated by a
brief push-button action and then transmits cyclically.
As soon as the push-button is forcibly separated from
the bus, this can be reported or an alarm can be trig-
gered.
Effect lighting
This example shows you how to program effect lighting,
for example for a display window. A long push-button
action switches between two different lighting scenes.
A short push-button action stops the toggling and trans-
mits a scene which switches off everything. The scene
module of the push-button is used to retrieve the scene.
Communication objects
You can select the following communication objects:
Number of objects = 2 (object A/B)
Object A/B = 1 bit
Object A: Action on release before the long operating time has
elapsed = toggles
Object B: Action on achieving the long operating interval = sends 1
and after a cycle time 0.
Action on release after achieving the long operating time
= no change.
Cycle time = e.g. 6 minutes.
Connect object A and object B with the switch object of the switch ac-
tuator.
Number of objects = 1 (object A)
Object A = 1 bit
Object A: Action on release before the long operating time has
elapsed = Sends 1 immediately and then cyclically.
Action on achieving the long operating time = No change.
Action on release after achieving the long operating time
= No change.
Cycle time = e.g. 10 minutes.
Connect object A with an object that listens cyclically for telegrams
(e.g. a safety object). The monitoring time set on the safety object
must be longer than the cycle time of the push-button. If the safety
object receives no telegrams from the push-button during this time,
a reaction which can be parameterised is activated (e.g. channel is
switched on).

Push-button, 4-gang plus with room temperature control unit and IR receiver
Multifunction with RTCU and FanCoil 1817/1.0
Sending edge commands - 2 byte
With this edge function, you can send a 2-byte object in
floating point format or in integer format (with or without
sign). A distinction is made between the normal edge
function and the extended edge function:
• With the normal edge function, you can specify which
actions should be carried out when a push-button is
pressed, and which should be carried out when a
push-button is released.
• With the extended edge function, you can also set the
actions before and after the long button actuation pe-
riod is completed.
Status indication
The status LED can:
• Be switched on or off continuously.
• Light up when pressed (for a long period), and go out
when released.
• Flash.
• Display the status of the status feedback object.
Normal edge function
With the normal edge function, you can specify which
actions should be carried out when a push-button is
pressed, and which should be carried out when a push-
button is released. These actions could include:
• Send value 1 or value 2:
You can specify two values and set whether and how
they are to be transmitted.
• Object sends its value:
The object transmits the value which it currently has.
Therefore you can, for example, transmit a value with
the sending group address which was previously re-
ceived via another group address.
•Noaction
Available values are the floating point value or integer
values with/without sign.

Extended edge function
With the extended edge function, you have a wider
range of functions available. For example, you can set
different actions for short and long presses of a push-
button, both for when the push-button is pressed and
for when it is released. You can also set a cycle time
which can be parameterised for the object.
|When parameterising, bear in mind that you need
to set all four types of push-button operation
(short/long press, pressing and releasing the but-
ton) in order to ensure that the push-button func-
tions as required.
|In order to read the object values, you may need to
set the Read flags manually.
The following activation sequence chart shows the
phases into which the pulse edge function is divided:
A description of the actions is given below:
• Sends [value]:
Transmits the current value and stops a cyclical trans-
mission.
• Sends [value] immediately and then cyclically:
If no cycle time is running, [value] is transmitted imme-
diately and a new cycle time is started. If a cycle time
is already running, it is interrupted, [value] is transmit-
ted and a new cycle time is started.
• Sends [value] only cyclically:
If no cycle time is running, [value] is transmitted imme-
diately and a new cycle time is started. If a cycle time
is already running, it is not interrupted; [value] is
transmitted after the current cycle time has elapsed,
and a new cycle time is started.
• Sets object value to [value] (readable only)
[value] is written into the object and is not transmitted.
Any active cycle time is terminated.
• Sends its value:
The current object value is transmitted. Any active cy-
cle time is terminated.
• Sends [value A] and after cycle time [value B]:
[value A] is transmitted immediately, and [value B] is
transmitted after one cycle time, regardless of wheth-
er a cycle time is already running or not (staircase
lighting timer function).
• None (stops cyclical sending):
No action is carried out, and any active cycle time is
stopped.
•Nochange:
The current action remains unchanged (e.g. “sends
value 1, then value 2 after a cycle time”).
