Wireless 1 zone brightness dimmer with touch panel T20-1 is used with single or many L4-M receivers, connected to DLC-D series LED drivers to power up ELS-L series LED lights. To launch LED lights brightness control:

1. connect L4-M receiver's output with DLC-D driver's 0-10V input
2. connect L4-M to power source ~230V AC or 12-24V DC
3. install x2 AAA battery in T20-1
   
4. match T20-1 dimmer and L4-M

Then all four steps are complete, simply press and hold key I to increase brightness, and key 0 to decrease. Short push I key to turn LED light ON or 0 key to turn it OFF.

Each T20-1 wireless dimmer can match with one or many receivers. To simultaneously control all available DLC-D drivers just match T20-1 with every L4-M receiver.
