What is V1 V2

[moondoggy4]

I have Apex unit and I do not know what the V/1 V/2 ports are used for. Thanks in advance

They are variable speed ports and can be used for Tunze pumps or controlling LED lights that are compatible with a 0-10v control.

Thanks, Is there something I can put in the port if I am not going to use it to prevent rust. Thfanks again

You can cut the plugs off of a extra network cable and plug them into the VS ports. Or you could seal the ports with tape. But the best course of action is to mount the Apex in an area of normal humidity or ventilate the stand if you must install the apex inside the stand.
