Lighting Control Rules
Rules for light intensity, spectrum, and high temperature are created and edited on the rules tab.
1. Setup the maximum (target) intensity and minimum intensity that the lights are capable of operating at.
2. Decide on a change rate for the light intensity; see the preview (5) to determine the transition times.
3. If spectrum controls are available, con gure the spectrum levels as desired.

1. Max Intensity Target intensity for the lights to reach.
2. Min Intensity Minimum intensity lights are capable of.*
3. ChangeRate Rate of change for dimming intensity.
4. Spectrum Spectrum controls for digital lighting xtures (LXD module.)
5. Preview Displays the ramp up/ramp down timing for dimmer intensity.
*Minimum intensity is where the dimming function will start when ramping up, and end when ramping
down. When ramping up, the output starts at 0 and jumps immediately to the minimum before ramping.
When ramping down, once at the minimum, the output will drop to 0 without ramping.
Temperature Dimming
Lighting can be dimmed in the event that temperatures exceed a limit in order to help reduce stress on
plants and limit the heating of the space. If dimming is enabled, the system will begin to dim at the ramp
rate until the temperature is reduced below the preset. If dimming is not enabled, the discrete output will be
shut down.
