To set up a circadian rhythm sequence, first create a sequence of type "Tuneable White"
The user creates a special sequence of actions that each contain three parameters: Delay, Light Intensity and Colour Temperature. The user then set the sequence to run at a certain time. Both intensity and colour temperature are optional parameters of each action - the user has full control over how their lighting is presented. zencontrol's circadian system can coexist with occupancy sensors, light sensors and switches. The controller will continue to modify the colour temperature of the light, even when it is off - so that if your room is unoccupied until 3PM when you walk in, the colour temperature of the light will be the correct value (intensity and colour temperature) prescribed by the sequence. No intensity changes will be sent to a target that is not on, but when triggered, the occupancy sensor will turn the lights on to the prescribed intensity, regardless of the occupancy sequence value.
A basic sequence might be to start at 9AM with the following actions:
Each action denotes the target colour temperature and intensity to be at after the delay time. Rather than sending a hard colour temperature change, the controller creates a slow transition to the next temperatures / intensity.
In this example, if we trigger the sequence at 9AM, lights will be instructed to go to 1800K at 25% intensity. As there is no previous value, the lights will go immediately to these settings.
For the next 2 hours, the controller will slowly transition the lights to 4200K at 61% intensity at midday.
At 9AM, the lights will be at 1800K ~25% intensity
At 10AM, the lights will be at 3000K ~43% intensity.
At 11AM, the lights will be at 4200K ~61% intensity.
Additionally, if a person was to walk into a room that is currently off at 10AM, the lights will turn on to 43% intensity.
To trigger the sequence, the user can create a new trigger on a target to execute on profile change:
Or, as a scheduled trigger (to the far right in the trigger view):
