Description
The push button is designed for the GRMS (Guest Room Management System) in hotels. It has touch-sensitive buttons, with which functions in the KNX building bus system can be called. With the KNX eTR DND/MUR Switch, guests in their rooms can select the service request ‘Do Not Disturb’ (DND = Do Not Disturb) or ‘Clean room’ (MUR = Make Up Room) service options.
A temperature sensor is integrated into the push button. An external temperature reading can be received via the bus and processed with its own data to create a total temperature (mixed value). Either binary contacts such as push buttons and window contacts or analogue T-NTC temperature sensors can be connected to 2 inputs. Communication objects can be linked via AND and OR logic gates.
The counterpart to the KNX eTR DND/MUR Switch is the KNX eTR DND/MUR Signal/Bell, which is installed outside the room.
Functions
- Button for ‘Do Not Disturb’ and ‘Make Up Room’ function
- Temperature measurements. Mixed value from own measured value and external values (proportion can be set by percentage), output of minimum and maximum values
- 2 inputs for binary contacts or T-NTC temperature sensor
- 2 AND and 2 OR logic gates each with 4 inputs. 8 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output from each gate can be configured optionally as 1-bit or 2 x 8-bit
- Configuration is made using the KNX software as of ETS 5
