Factory 

setting

•  The LL60/2-E-DA-iC driver has 2 output channels used to control 

the intensity and temperature of white colour as well known as 
“Tunable White”

•  These drivers respond to DALI type 8 (DT8) commands, which in 

practice means that they only have 1 common address for both 
output channels

•  The tunable white level of intensity and colour temperature can be 

set either with a DALI command or by Switch-Control

•  The driver will operate correctly once tunable white LED module 

parameters are programmed to the driver. Use “Helvar DALI 
Driver Configurator” for the parameter setting

•  Default LED module parameters are set according to Helvar iC 

LED module specifications

•  See Helvar DALI Driver Configurator user guide for more 

information how to set the parameters to the driver

Retractive Switch

Helvar iC drivers provide the simplest form of control in tunable white 
with Helvar patented single switch Switch-Control functionality. With 
single push button the user is able to control both the light intensity 
and colour temperature to the desired level. The system synchronises 
the light levels and CCTs every time the colour temperature is 
adjusted to ensure pleasant user experience and  uncompromised 
lighting comfort. More information about the functionality can be 
found in Switch-Control user guide at www.helvar.com.
