CAUTION
Bi-stable relays are used in the device, which may result in incorrect load control due to an undefined relay state on delivery!

There is a risk that the connected drive motors are destroyed.
During start-up, you must make sure that all relay contacts are open before switching on the load by applying the KNX bus voltage. Observe the start-up sequence:

  1. Switch on the KNX bus voltage.
  1. Wait approx. 10 s.
  1. Connect the load circuit.
