2 Operation
Each channel can be switched on and off independently of all parameters using the buttons on
the device. A status LED displays the current switching status.
All bus telegrams are ignored with manual operation switched on (manual button) and the
channels are to be operated exclusively via the buttons.
Once the bus voltage has been connected or after a bus reset, it might take a few seconds until the
relays switch.

Object 0 Switch object, threshold as a percentage, threshold 0..255,
threshold EIS 5 (DPT 9.xxx), threshold 0..65535
Input object: this object activates the set channel function (see parameter: Channel function).
The set channel function can either be activated via 1-bit telegram or by exceeding a threshold
(8- or 16-bit telegram).
function via
Exceeding the
threshold
Object 1: Logic input in AND gate, in OR gate, in XOR gate
Only available if link is activated (Configuration options parameter page).
Forms a logical link together with the input object to activate the channel function.
Object 2: Block
Blocks the channel function.
Responses to setting and cancelling the block can be configured if the block function has been
activated (Configuration options parameter page).
Object 3: Call up/save scene
Only available if the scene function has been activated (Configuration options parameter page).
This object can be used to save and subsequently call up scenes.
Saving stores the channel status.
It does not matter how this status is produced (whether via switch commands, central objects or
the buttons on the device).
The saved status is restored when it is called up.
All scene numbers from 1 to 64 are supported.
Each channel can participate in up to 8 scenes.

Object 4: Block scenes = 1, enable scenes = 1
Blocks the scene function with a 1 or a 0 depending on the configuration.
As long as it is blocked, scenes cannot be saved or called up.
Object 5: On/Off feedback
Reports the current channel status.
The status can also be inverted depending on configuration.
Object 6: Time to next service, operating hours feedback
Only available if the hour counter function is activated
(Configuration options parameter page).
Reports, depending on selected Type of hour counter (Hour counter and service parameter
page), either the remaining period to the next service or the current status of the hour counter.
Object 7: Service required
Only available if the hour counter function has been activated (Configuration options parameter
page) and Type of hour counter = Counter for time to next service.
Reports if the next service is due.
0 = not due
1 = service is due.
Object 8: Switching with priority, reset service, reset operating hours

Switch actuators RM 4 H, RM 8 H
switching on 2 relays if several are activated at the
same time.
The shortest delay is achieved by using the Central
switching object.
When switching on via individual telegrams (1
telegram per channel), the bus running times and the
sequential processing of commands cause an
additional delay.
This can help avoid high current peaks when devices

5.2 Temperature-controlled domestic water heating
Task:
The domestic water temperature must be maintained at a minimum of 50 °C using a heating
element.
The water temperature is measured using a remote sensor (e.g. order no. 9070321).
The sensor is connected to a TA 4 S input and the temperature value is sent to the bus.
Channel C1 receives the domestic water temperature via a threshold object and switches the
heating element to relay output.

6.1 The scenes
6.1.1 Principle
The current status of a channel, or a complete
device can be stored and retrieved later at any time via the scene function.
Each channel can participate simultaneously in up to 8 scenes.
Scene numbers 1 to 64 are permitted.
Permission is required to access scenes for the relevant channel via parameter.
See Activate scenes parameter and Scenes parameter page.
The current status is allocated to the appropriate scene number when a scene is saved.
The previously saved status is restored when a scene number is called up.
This allows a FIX system to be easily and conveniently integrated into any chosen user scene.
The scenes are permanently stored and remain intact even after the application has been
downloaded again.
See All channel scene statuses parameter on the Scenes parameter page.

6.1.3 Teach-in scenes without telegrams
Instead of defining scenes individually by telegram, this can be done in advance in the ETS.
This merely requires setting the All channel scene statuses parameter (Scenes parameter page)
to overwrite at download.
Accordingly, the required status can be selected for each of the 8 possible scene numbers in a
channel (= Status after download parameter).
The scenes are programmed into the device after the download has been completed.
Later changes via teach in telegrams are possible if required and they can be permitted or
blocked via a parameter.
6.2 Conversion of percentages to hexadecimal and decimal
values
0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
All values from 00 to FF hex. (0 to 255 dec.) are valid.
