After reading in the manual it says like this:

Connector „RGB LED“
Connector for up to three LEDs or one two-color or RGB illumination module
(not included in delivery).

Using a RGB Module like the one here , inside a plug like this one , that goes inside a reservoir on the bottom (could that be used inside this reservoir here (thats made from 3 different pieces) ?, if not, which reservoirs compatible with this combination ?) one could control the led based on water temperature, or delta, (if two sensor are within the same loop at different points) to make it different colors.

The question is, if one can connect more that 1 RGB illumination modules, meaning 2, to the aquaaero 6 XT, or do i need to get something extra ?

Thanks for all the answers Shoggy, here, and in my other Threads.
Now, how could i use 2 of these RGB Leds, if the aquaero 6 can drive only one ?
Through eny other equipement you may offer, ?
Or am i stuck with only one ?

Quoted from "Shoggy"

We do not offer anything that will work with two ... yet

Now theres something thats going to need to get upgraded ! At least now i know !
