VERA / FIBARO controllers

  • Select 'Add-device' in the Vera User Interface or press the "+" button for 2 seconds on the Vera Z-wave controller.  The orange LED will flash slowly on the controller 
  • Enable the DIP switch 1 of SRT321 thermostat (ON).
  • Rotate the selectionwheel of SRT321 untill a  “L” is displayed on the screen.
  • Press the wheel to put the z-wave thermostat in inclusion mode. A flashing “L” is displayed and then and changes to “LP”. Now you should be able to see thethermostat in the VERA or FIBARO controller
  • Only for Vera controllers : cancel “insert mode”; select the blue “Refresh” button on the top right. The message “Unit busy” will be displayed in the web console interface for a little while.
  • After inclusion, the z-wave thermostat will  appear on the console . Now it needs to be configured.
  • Select the letter “n” by rotating the wheel and press the wheel. This adjusts the room temperature and the warning message disappears.
  • Change the DIP switch # 1 setting to normal mode (OFF), remove the battery for 5 seconds and re-insert.
  • It is possible now also to locally change the temperature by turning the thermostat dial. The configuration and the change will be displayed in the VERA web interface.
  • After inclusion of the z-wave thermostat in the controller, some configuration settings have to be set in order to make it work properly in the network and report the temperature to the controller.
