Dynamic Color Recipes

Dynamic Color Recipes (abbreviated DCR) adjust brightness and color automatically over time.

They can be used for circadian schedules, RGBWAF color transitions, and smooth fade-based lighting scenes.

It works together with Room Light Control and uses the same room outputs.

Recipe Graphs

Dynamic Color Recipes are configured with graphs. A graph defines how room lighting should evolve across the day.

Graph availability

The available graph count depends on the product model:

4 DALI channels model: 16 graphs.
1 DALI channel model: 4 graphs.

Each graph contains 8 support points and can be assigned to one or many Room Light Controls.

Support points

A support point defines:

A reference time.
A target brightness.
A target color.

You can combine several points to create gradual morning, daytime, and evening transitions.

Color types

The graph color type determines how color values are interpreted.

Color Type	Value	Description
TC	0	DT8 color temperature Tc value (mirek/mired)
XY	1	DT8 x/y coordinates
RGBWAF	2	DT8 Red, Green, Blue, White, Amber, Free Colour

For TC, user-facing values are in Kelvin (K).

Protocol conversion note:

Tc is in mirek (also called mired):

Mirek = 1000000 / Kelvin.

Kelvin = 1000000 / Mirek.

Example: 4000 K corresponds to 250 mirek.

Time types

Each support point uses one time type.

Time Type	Description
Fixed	Uses a fixed configured time
Sunrise	Uses sunrise time with optional offset
Sunset	Uses sunset time with optional offset

Recipe Operation

Dynamic Color Recipes transition smoothly between active support points.

Interpolation is updated every 60 seconds.

For sunrise and sunset based points, offset and clamp settings can be used to keep transitions within a preferred time window.

Interaction With Room Light Control

Daylight Harvesting

Dynamic Color Recipes and Daylight Harvesting are mutually exclusive in operation.

Starting Dynamic Color Recipes stops daylight harvesting.
Starting daylight harvesting stops Dynamic Color Recipes.

Manual Override

Manual control of the room output temporarily stops Dynamic Color Recipes for that room.

Occupancy commands

Dynamic Color Recipes can be started or stopped through Room Light Control command logic.

Related BACnet properties: Command, Occupied_Command_Command, Warning_Command_Command, Unoccupied_Command_Command, Occupied_Mode_Command_Enable.

Fade behavior

An optional graph fade time can be used to apply smoother transitions when a new recipe target is applied.

Configuration Workflow

Select a recipe graph.
Choose the color type.
Configure support points for key moments of the day.
Assign the graph to the target Room Light Control.
Validate behavior during occupied and unoccupied periods.
