Widgets and Key Functions

The Next Generation Saturn and Saturn Zen wall plates support up to 16 “Widgets”. For those familiar with existing key units, Widgets are a bit like the “Blocks” in the older key units, and a bit like the Widgets in the eDLT, however the capabilities (and rules) are a little different to both (more on that later).

Each Widget's behavior is configured firstly by selecting its Type. For example, you would select a Lighting Widget to do normal Lighting operations like turning a light on/off or dimming it, whereas you would select a Scene Widget to interact with a Scene, or a Shutter Relay widget to operate a blind connected to a C-Bus shutter relay.

The following Widget types are available.

Widget Type	Description
Lighting	Traditional Lighting Application functions
Timer	Dedicated timer functions for Lighting Application
Shutter Relay	Dedicated one, two, and three key functions for Shutter Relays using Level Translation mode
Enable	Dedicated functions for Enable Application
Fan Control	Dedicated Widget for single key control of a C-Bus Sweep Fan Controller
Scene	Scene functions
Sequence	Sequence functions
Audio	Native control of audio parameters using the C-Bus Audio Application
Multi-Toggle	Dedicated widget for simple toggle control of up to 8 Lighting or Enable groups
Linked	Used to perform an action based upon an event on another Widget
Unused	No function

Once the Widget type is selected and the Key Function is chosen, which defines what action it does when activated by a key.

NOTE: Unlike the old key units, the Key Function is a property of the Widget.

Finally, depending on the Key Function selected, additional parameters may need to be set. For example, a "Preset" Key Function requires you to specify the level you want the preset to set, whereas any of the Key Functions that perform dimming require you to specify the Ramp Rate you would like to use.

Unlike old key units, the same Lighting Group may be used in more than one Widget. This is used where 2 keys are desired to control the same group (for example "On/Up" and "Off/Down" Key Functions) then two Lighting Widgets are used. One with Key Function set "On/Up" and one with Key Function set to "Off/Down".

The indicator on and off state colors are also a property of the Widget, which means each Widget can have any color defined for each state.

Similar to old key units:

Key to Widget mapping can be changed.
A single Key may be mapped to multiple Widgets, or multiple Keys can map to the same Widget (although this rarely makes sense to do).
Indicator on a physical Key can be controlled by a different Widget to that which the Key is controlling.
