Tunable White – Configuring CCT levels

When SNS210 is used with a FlexTune SR driver, the Color Temperature (CCT) of the luminaire is an additional configuration parameter. This applies to the automatic/manual ON level as well as the two scene recall levels (short press of the scene buttons). Note: In addition to the scene recalls, press and hold of the Scene-1 button will gradually increase the CCT and press and hold the Scene2button will gradually decrease the CCT.

How to do?

• Configure the color temperature (CCT) for the automatic/manual ON-level in the “Edit configuration” screen as shown below in the three left pictures. • Configure the color temperature (CCT) for the Scene buttons in the “Configure a scene” flow as shown below in the four left pictures. This can be done for each of 2 the scene buttons on the 4 button ZGP switch. The Brightness can be configured as well for each scene.

Remarks: • When configuring a scene with a four-button switch, two sliders appear on the screen: one for light-level setting and one for CCT setting. While adjusting the light level, the system directly responds. While adjusting the CCT, the system does not respond immediately, and the set values appear after “save and apply” the configuration. • Mixing Tunable White fixtures with non-Tunable White fixtures in one group is not supported. • In case different types of tunable white fixtures are mixed in a group, e.g., when combining TW point drivers with SNS410 + TW linear drivers, the system with smallest CCT range must be commissioned first (TW linear driver in this example) to avoid issues at the edges of the CCT range.
