How to connect LS-5P to White/Yellow COB LED strip？

As title says:

- I get W & G & B & R & VCC on the LS-5P controller

- also on the LED strip there are 3 contact points: +24V & W & C

I assume I should connect VCC to +24V, and then W to W, but what should I do with the C on the LED strip?

Thanks in advance
