3. Function

1) Along with DALI driver and lamps, MS13 realizes the self-adjusting daylight harvesting function.


2) After the successful setting with remote control or digital encoder, when the external light illuminance becomes bright, the daylight sensor will lower the brightness of the lamp.When the external light illuminance becomes dark, accordingly the light sensor will reduce the brightness of the lamp. The brightness is adjusted to make the light illuminance value of the environment in a relatively constant state.


3) Daylight harvesting function setting method and steps with remote control: after the 5S product initialization, DALI dimming is 100%, press DH MODE button of the remote control or long press the digital encoder 3S to enter the daylight harvesting mode. The light illuminance of the mode can be adjusted to an appropriate brightness, otherwise, it will automatically learn the current brightness as constant brightness after 3S.


4) Daylight harvesting function setting method and steps with digital encoder (DH/dimming)
