Frequently Asked Questions - WGCXR121AS HAGER

What is the Hager WGCXR121AS used for?

The Hager WGCXR121AS is a KNX actuator for controlling lighting, blinds, or small loads in home automation systems. It provides 4 relay outputs for switching or shutter control.

How do I power the WGCXR121AS?

It is powered via the KNX bus (29 V DC SELV). No external power supply is needed. The bus voltage is provided by a KNX power supply unit installed in the distribution board.

Can I use this actuator for dimming?

No, the WGCXR121AS is a switching actuator with relay outputs. It cannot directly dim lights. For dimming, use a KNX dimming actuator or add a dimming module.

What is the maximum load per output?

Each relay output can switch up to 16 A at 250 V AC resistive load. For inductive loads (e.g., motors), ensure a power factor ≥ 0.6 and reduce load accordingly.

How do I program the WGCXR121AS?

The device is programmed using ETS software (Engineering Tool Software) from the KNX Association. Connect via a KNX interface, assign physical address, and configure parameters.

Is the WGCXR121AS compatible with Hager tebis systems?

Yes, it is fully compatible with Hager tebis and tec KNX home automation systems, as well as other KNX-certified products.

What does the LED indicator on the device mean?

The red/green LED indicates operating status: green = normal, red = error (e.g., bus failure). Refer to manual for detailed signaling.

Can I use the actuator outdoors?

No, the IP20 rating means it is suitable only for indoor use in dry locations. It must be installed in a weatherproof enclosure if used in damp areas.

How do I reset the actuator to factory settings?

Press and hold the programming button (approx. 10 seconds) until the LED flashes red. This will reset the address and parameters. Re-channel then in ETS.

What are the dimensions and mounting requirements?

Dimensions: 90 x 36 x 64 mm. It snaps onto a DIN rail (TH35) in the electrical distribution board. Allow at least 10 cm clearance for ventilation.
