Page 3: General Information
General Information Kristal is a complete line of capacitive keypads designed to control KNX devices. The keypads are available in the format 80mm x 80mm for installation in round connector blocks (BX-qx) or in the format 120mm x 80mm for installation in Italian connector blocks Model 503 (BX-Rx). Both models are available in the White (W) and Black (B) colour options. Here below are the products' identification codes: BX-Q02B 2-control model 80x80, Black BX-Q02W 2-control model 80x80, White BX-Q04B... -
Page 4: Product Features
Product Features The buttons interface is powered via the Konnex bus and does not need any additional power supplies. The keypads have BLUE backlighting behind each control and WHITE backlighting all along their transparent edges to illuminate the wall. Both are controllable with suitable ETS communication objects. The device is equipped with a buzzer, also programmable via ETS, in order to offer the best acoustic feedback. The interface is also equipped with a proximity sensor to turn on as the user's hand moves closer. The IP20 casing is designed for installation inside connector blocks intended to accept conventional push-buttons. -
Page 5: Ets Library
ETS Library The ETS Library features a number of parameters used to characterise the operation of each control of our keypad. The parameters are conveniently divided into pages for the configuration of each control, with an added main page for the selection of which device type should be installed. 3.1 General Parameters Below is the General parameters page reached by activating the ETS control Edit Parameters. This ETS library is applicable to a number of products which differ in shape, colour and above all, number of controls. Therefore, it is first of all necessary to correctly select the number of available keys on the device that you are installing, so that the Library can... - Page 6 Parameters are listed here below that may affect the general operation of the device. The first relates to the enabling of the Buzzer to ensure an acoustic feedback response when a control is activated. The buzzer can be turned off by enabling the Always off function.
- Page 7 3.2 Key1, Key 2, Key3, …Key12 Below is the image typically opening the key configuration dedicated page. The first parameter, Mode, is the most important one and determines the mode of operation of the corresponding key. There are 6 different modes of operation that will be described below - including the possibility of disabling the control.
- Page 8 Finally, it is possible to activate the Long press function mode. This allows two events to be managed with each input: the short press event to activate a certain KNX control, or the long press event to activate another KNX control.

Page 9: Switching Mode
In the event that Contact type is normally closed, the operation logic that we have just described is completely reversed. The Switching mode exposes an extremely simple 1 bit communication object to transmit controls to the other KNX devices. - Page 10 The performance of the button interface changes when the Long press function is enabled. If the long press control is not expected, the KNX telegram is sent immediately, as soon the pressure applied on the button is felt (rising edge).

Like in the previous case, Contact type is the property that determines with which event the notification of telegrams on the KNX bus is synchronised. If Contact type is defined as normally open (standard) the datum is sent on the rising edge, therefore it is worth 1 when the contact closes and 0 when the contact opens. -
Page 12: Dimmer Mode
3.2.3 Dimmer Mode This is the function suitable for adjusting the brightness of a dimmable light. The Dimmer function is one of the modes that automatically enables the use of a Long press function to have a second control available. The Short control is used to switch the light on and off and enables a 1bit communication object named Switching;... - Page 13 After obtaining the desired brightness we will be able to release the button by automatically causing the sending of the dimming STOP control. Like in all previous cases, the Contact type property defined as Normally closed will determine the reversal of the operation logic. The effectiveness of the adjustment depends above all on the speed with which the dimmer changes the brightness and is a parameter generally settable from the actuator.

Page 14: Scene Mode
Therefore every time that a short press is applied the configured scene will be recalled. To store a new scene consists in sending a byte to the KNX bus with value (ID + 64). Sending the memory storage control is assigned to the Long function. -
Page 15: Blind - Shutter Mode
3.2.5 Blind - Shutter Mode This is the function that allows control over the shutters and blinds actuators. The main feature of a shutter/blind control is the fact that it is actuated via two different group addresses: the first to control the shutter movement, and the second to control the shutter stop and the venetian blind movement. - Page 16 The movement control can be programmed both to raise the roller shutter (UP = 0) and to lower it (DOWN = 1). When a given movement is assigned to an input, it should be borne in mind that two inputs are required to ensure full actuator control: one to raise and the other to lower the roller shutter.
