Frequently Asked Questions - 834.28 G JUNG
Can the JUNG 834.28 G dimmer be used with LED lamps?
Yes, the dimmer is compatible with dimmable LED lamps, but ensure the total load does not exceed the rated maximum (typically 100 VA for LED). Some LEDs may require a minimum load; refer to the lamp specifications.
What is the maximum load for the 834.28 G dimmer?
The maximum load depends on the lamp type: up to 400 W for incandescent/halogen, and up to 100 VA for dimmable LED/CFL. Always verify the exact ratings in the product manual.
How do I wire the JUNG 834.28 G dimmer?
Connect the live (brown) wire to L terminal, the switched live to the load terminal (marked with arrow or L'), and neutral if required (usually not). Ensure power is off before installation. Follow the provided wiring diagram.
Does the dimmer have a memory function for the last brightness level?
Yes, the 834.28 G features a memory function that recalls the last set brightness level when turned on again after a short off period. A long off period may reset to full brightness.
What is the recommended mounting depth for the dimmer?
The dimmer requires a flush-mounted wall box with a minimum depth of 40 mm. Ensure sufficient space for cables and ventilation.
Why is my lamp flickering when dimmed?
Flickering can occur if the lamp is not dimmable, the load is too low, or the lamp is incompatible. Try a different dimmable lamp or adjust the minimum brightness setting (if available). Also check for loose wiring.
Can I use the dimmer with a three-way (multi-location) switch setup?
No, the 834.28 G is a single-pole dimmer and is not designed for multi-way control. For multiple locations, use a compatible JUNG remote dimmer or add a companion switch.

Clean the knob and faceplate with a soft, dry cloth. Do not use abrasive cleaners, solvents, or water. For stubborn dirt, slightly dampen the cloth with mild soap solution and wipe dry immediately.
Is the dimmer suitable for use in bathrooms or outdoor areas?
