Recall scene
Recall a scene previously stored (temporarily if connected to a Helvar router system).
Scenes are sets of lighting levels and can make use of any combination of channels.
This option is always available, even when password protection is applied to other options.
Range: scenes 1–16
Save as scene
The levels which are currently active for all channels of the dimmer are applied to this scene. You can recall stored scenes
in the ‘Recall scene’ menu (see above).
Range: scenes 1–16
Default scenes
Default lighting scenes can be applied to the dimmer channels.
Default scene levels are: scene 1 = 100 %; scene 2 = 75 %; scene 3 = 50 %; scene 4 = 25 %.
In addition, the following default scenes are available when a presence sensor is used: scene 14 = 10 %, presence sensor
min.; scene 15 = off, presence sensor off; scene 16 = 100 %, presence sensor on.
Note: Lighting levels are NOT changed automatically once you apply default scenes. However, once you recall a scene, lighting
is set to the levels for that scene.
