Description of application and parametersApplication "2-button blind"KNX Technical Reference Manual 1473-1-8905 / 2CKA001473B8905 │6210.15 Application "2-button blind"NOTEThe application is valid for the following parts of the device:■ Button 1 / rocker 1■ Button 3 / rocker 2Via the application "2-button blind", blind movement and/or slats adjustment commands can besent to connected blind actuators with a short or long actuation of the button. A short buttonpress always triggers a travel command and a long button press always triggers a slatsadjustment or stop command. In each case, the "2-button blind" application makes a separateset of parameters and communication objects available for the right or left side of the button.This thus facilitates controlling a blind using one side of the button and assigning a "buttonorientated" function to the other side of the button. The control always remembers the lastaction performed on the side of the button that is assigned with the "2-button blind" application.For example: If a blind was lowered and halted at half height via a long press of the button, thena renewed short press of the button will raise the blind.10.15.1 General parameters - Time for long operationOptions: 00.300 ... 03,000A differentiation can be made between a short or long operation of the button. With a shortoperation of the button, the next level forward is switched to in each case. With a longoperation, the first level is activated. Thus with a long button press a jump back from everyposition to the first level is possible, without having to run through the remaining levels.Via the "Duration of long operation", the time is specified from which a long button press isrecognised and the object values are reset. The first level must be set again with a press of thebutton. Any time from 0.3 to 3 seconds can be set. A typical value after which a jump-back tolevel 1 is made is 0.4 s.10.15.2 General parameters - Object typeOptions: 1 bit1 byte 0 - 100%Via the parameter object type, you can specify whether the blind control occurs via two 1-bit ortwo 1-byte communication objects "Move" and "Adjust".If 1-byte was selected as object type, the communication objects can be connected with 1-byteposition objects from blind actuators. For example: One side of the button could lower the blindto 50% with slats closed 50%, while the other button side can lower the blind to 80% with slatsclosed 100%.
