Button interface, 8-gang Komfort for KNX

Features

• According to the variant, two, four or eight independent channels that operate as inputs or as outputs depending on the ETS parameterisation.
• Common reference potential for all channels.
• Outputs: Connection of LED. Short-circuit-proof, protected against overload and polarity reversal. Parallel switching of outputs possible, for consumers with higher current requirements
• Inputs: Pulse current to prevent contact contamination due to formation of an oxide layer on the connected contacts.
• Channels can be activated and deactivated individually.
• Adjacent activated channels can be combined.

Possible parameterisation depending on the selected channel function

• Contact type can be set.
• Switching: Command when pressed and/or released can be set (No reaction; Switch on; Switch off; Switch over).
• Forced setting: Command when pressed and/or released can be set (No reaction; Forced active, Switch on; Forced active, Switch off; Forced inactive).
• Dimming and colour temperature: The command when pressed, time between switching and dimming, dimming in different steps, telegram repetition if pressed for a long time and sending of a stop telegram at the end of pressing can be set.
• Blind/shutter/awning/roof window: Command when pressed and command sequence can be set.
• Value transmitter: Data point type, value range and value can be set. As an option, the value adjustment can be activated by pressing and holding the button.
• Scene auxiliary unit: Scene number can be retrieved or switched by briefly pressing the button. If the button is pressed and held, the memory function is executed as an option.
• Short and long button press: Up to two telegrams can be sent to the KNX by pressing a button. The transmission behaviour can be set and the time for short and long actuation can be adjusted. The mode of operation of the channels can be set separately.
• Room temperature controller operating point: The mode of operation (operating mode switch-over, forced operating mode switch-over, presence function and target temperature adjustment) can be set.
• Behaviour after bus voltage recovery can be set.
• Disable function can be set.
• Cyclic transmission can be set.
• Channel function “Door/window status”: When door or window contacts are used, the different window or door statuses can be evaluated (open, closed, tilted, locked, unlocked).
• Evaluation of a leakage/condensation sensor.
• Temperature measurement by connected sensor possible.
• Temperature measurement can be supplemented by external value via bus. Measured values can be weighted and calibrated.

Pulse meter

• Metering interval can be set.
• Number of pulses required at the input per reported meter pulse can be parameterised on the KNX.
• The number of meter pulses required for a meter status change can be parameterised.
• Each channel contains a main meter and an intermediate meter.
• Main and intermediate meters can be set separately as up or down meters.
• Start and end values of the meters can be specified via parameters or communication objects.
• Meter status can be queried via the KNX or transmitted automatically.
• Response after the meter has timed out can be parameterised.
• The pulse meter can be reset via the KNX (meter reset).

Logic functions

• The device has 8 internal logic functions.
• Invert input.
• Logic gate with up to 4 inputs: AND, OR, exclusive OR, inverted AND, inverted OR, inverted exclusive OR, AND with return.
• 1-bit to 1-byte converter with input filter, blocking object and specification of output values.
• Blocking element with filter and time functions and blocking object.
• Comparator for values with 9 different input data formats and many comparison operations.
• Limit value switch with hysteresis with upper and lower threshold values for 9 different input data formats. Including specification of the 1-bit output values.
• The logic functions have their own KNX communication objects and can process telegrams from the button interface or other bus devices.
