Extended Product Information

FAQs

Can this actuator dim my lights?

No, this is a switch actuator designed for on/off functionality, not dimming.

Is this device compatible with KNX systems?

This device is specifically designed for the Free@home bus system protocol.

What is the maximum load per channel?

Each individual channel is rated for up to 16A.

Does it require a separate power supply?

It operates on 230V AC, which is typically provided by your main electrical distribution board.

Can I operate the switches if the smart home system fails?

Yes, the device includes physical manual override buttons for each channel.

What does the IP20 rating mean?

It means the device is protected against solid objects larger than 12.5mm but has no protection against liquids; it must stay dry.

Troubleshooting

Channel does not respond to bus command

Check the status LED on the unit. If the LED is off, verify the bus connection and address the device via the Free@home system software.

Load will not turn on despite manual trigger

Check the external circuit breaker to ensure the load is receiving power and verify that the relay is properly wired to the output.

Device is not visible in the system interface

Verify that the bus line is correctly terminated and that the device is receiving 230V AC power.
