Operation

Minimum brightness

The dimming range is 5-100%, but some load types flicker when dimmed all the way down to 5%. Setting a minimum brightness above that point raises the floor of the dimming range so the load never dims low enough to flicker.

Set: dim the load to the level you want as the new floor, then press and hold Min. Set on the device until the load flashes. From then on, the load only dims between this level and full brightness.

Delete: dim the load to full brightness, then click Min. Set once. The load flashes to confirm the reset.

The same Min. Set button also doubles as the control for startup brightness, the level the load returns to at power-on. The manufacturer's documentation does not detail that procedure; contact Atios support if you need it.

Push switch operation

When a push switch is wired to the DA terminal instead of a DALI bus (see Installation):

• Click: switch the load on or off.
• Press and hold: increase or decrease brightness.
