  • The switch must not be connected to any mains. It is powered directly from the DALI line.
  • The DALI line is not SELV. It must be treated like LV mains and treated with the same precautions and wiring regulations.


By default the zc-rotary is configured to have 3 control device instances corresponding to rotate clockwise, rotate counter clockwise and push. The push instance supports both long and short press functions. Actual function is dependant on the configuration of DALI-2 application controllers connected to the DALI line.

With the zencontrol control system the rotary is ideal for tunable white control.

  • Rotate Left / Right – Brightness Up and Down
  • Short Press – On/Off
  • Long Press – Warmer / Cooler
