    • The device does not contain any parts that can be replaced or repaired by the user. • The manufacturer of the VAV unit (OEM) is responsible for ensuring that the VRP-M- controller is installed and set correctly as well as for the overall precision of the VAV unit. If replacement devices are ordered, they are configured by the OEM at the factory according to the installed system.

  • Page 15: Connection Of The Vrp-M-Tool

    MP connection (terminal 4). A level converter is required for communication, e.g.: ZIP-RS232. Conventional operation (PP) VRP-M runs with a locally connected reference signal (0 ... 10 V on connection 3). VRP-M detects that there is no tool connected and switches back to the connected analogue reference signal automatically after 120 s.

  • Page 16: Bus Operation

    2...8 s, depending on the number of connected bus users and integrated sensors. The local VRP-M control function is not affected by the cycle time. The cycle time of the MP-Bus must always be taken into account, however, when selecting setpoints via the MP-Bus.
  • Page 17 Bus fail function Last setpoint The VRP-M saves the current setpoint, i.e. the last setpoint to have been received from a bus master (VRP-M-Tool, UK24LON). If the MP network fails, the connected VRP-M detects this and retains this setpoint until it receives a new one from the MP master.
  • Page 18 – VAV-Compact NMV-D2-MP Product Information – Bus and communication systems section Addressing If the VRP-M system solution is integrated in a bus system, each connected VRP-M must be assigned an MP address in the range 1 ... 8. Procedure – Start the addressing procedure on the MP-Bus master with the VRP-M-Tool, UK24LON, etc.
