LEARNING PROCESS

To learn in Tree devices please read here.

Icon Exclamation Mark LoxoneThe status LED flashes orange initially on power-up. After the dimmer has been learnt in, the LED flashes briefly green for confirmation, then both LEDs are permanently off.
If the LED flashes red, check the wiring. Details for analysis can be found here .

CONFIGURATION

Once the dimmer is listed in the peripheral screen. Drag and drop the dimming outputs to the configuration page.

WIRING

Wiring Loxone RGBW Tree DimmerIf “Individual dimming channels” is selected as PWM configuration in the properties of the device, the channel assignment is as follows:

Red    -> Dimmer 1
Green -> Dimmer 2
Blue    -> Dimmer 3
White  -> Dimmer 4

IDENTIFICATION

To identify the dimmer in the cabinet, click the dimmer in the periphery in Loxone config. The status LED on the RGBW Dimmer will then flash quickly alternately red green. If a channel of the dimmer is selected, this fades up and down and is thus clearly identifiable. The RGB output fades first red, second green and blue third.

Icon Exclamation Mark LoxoneThe PWM dimmer should be placed as close as possible to the LED strip. The cross-section of the 24V voltage supply should be such that the voltage drop is a maximum of 1V.

 

The voltage drop can be calculated using the following formula:

ΔU = I · R = I · ((2 · L · ρ) / A)

I … Current [A]
L … Cable Length [m]
A … Cable Cross-Section [mm²]
ΔU … Voltage Drop [V]
ρ … Material Specific Resistance [( Ω*mm²)/m]

ρ= 0.0172 (for Copper)
