## What is DNR light?

DNR requires iOS 9.3, compatible with iPhones 5s, 6 and 6 plus and following models

This app is for simple and user-friendly adjustment of the ISYnet DNR Touch-Controller and the DNR-Clock. DNR stands for day-night rhythm and is a system for controlling the light in a circadian biological rhythm (day-night rhythm).
With the DNR modules, you can easily customize your DALI luminaries with 2 different colors for your human centric lighting (HCL).
The following parameters can be set:
      -  brightness curve
      -  color temperature curve (light color)
      -  switching times
      -  features of the external buttons
      -  locking of the manual mode
      -  motion sensor functions

To transfer the parameters, it simply uses the LED (flash) from your iPhone. Thus you don't need to connect via WiFi or Bluetooth what sometimes causes a lot of trouble. Simply hold your iPhone in front of the device and tap "send".
