The controllers and push-buttons of the KNX eTR series are switch size and flexible in installation. The clear design language provides quick and easy access to building technology. The real glass surface is elegant, hygienic and durable at the same time.
The controllers and buttons can be installed on the wall with or without a switch box. The size is approximately 82 mm × 82 mm and has a mounting depth of approx. 12 mm, making it similar to a normal switch. The colours deep black RAL 9005 and signal white RAL 9003 match many current furnishing styles. A temperature sensor is integrated in all devices of the eTR series so that no further sensors need to be installed for room temperature control.
All devices of the eTR series are supplied via the KNX bus voltage, therefore only the KNX TP cable is required for connection.
The individual feel-good temperature can be easily set with the heating controllers KNX eTR 101 and KNX eTR 201/202 Sunblind. The target temperature is displayed in illuminated digits and can be changed using the intuitively understandable “Plus” and “Minus” buttons.
In addition, the 201 and 202 models have up/down touch buttons for positioning sunblinds and darkening.
Functions of the KNX eTR series:
PI control of heating and air conditioning
The temperature PI controller in the application can be used to control single- and two-stage heating and cooling systems, including combined systems with switchover between heating and cooling. The reference here is always the comparison between the measured actual temperature and the desired target temperature.
Practical extra: The area function
The double and four-gang versions of KNX eTR M and KNX eTR MultiTouch have an additional switching function when touching several fields. All you need to do is wipe over the button or briefly place your hand on it to trigger a scene or switch on the light, for example.
The touch buttons KNX eTR M1, M2 and M4 are flexibly programmable. For example as a light switch, for dimming, to move shading up and down or to call up scenes. With an integrated sensor, they unobtrusively detect the temperature on site.
Printed icons show immediately that the KNX eTR MultiTouch push-button is used to adjust light, temperature and shading. An integrated sensor invisibly detects the room temperature.
