Chiller feed return lines question

[y-not]

Okay, I'm sure EVERYONE follows EVERY post I've ever made (yeah, right) but just in case, here's the dirt.
RSM 250, chiller has been installed for about 2 months and is running like a champ!

Almost forgot, the chiller pump is a separate pump. I am not using the filter pump to run water to/from the chiller.

No problems what-so-ever.

Today I move the chiller into the basement, directly below the tank. Stay tuned for photos on that project....
Anyway, while I was running PVC and testing for leaks, etc...I started thinking about how the feed from the pump and the return from the chiller are both feeding and returning to the same chamber. The one to the right of the skimmer.

Chances are, I'm over thinking this. I tend to do that.

If the chilled water is being dumped into the same chamber that is feeding the chiller and the chiller turns on/off based upon the temp of the supplied water, wouldn't this cause the chiller to think that the temps in the tank are cooler than they really are?

What if I were to, somehow, move the return to another location?

My temp probe is sitting to the left of the skimmer. In turn, it's reading the temp of water that's been returned from the tank. Not what's in the chamber that the chiller pump & return are in. So I feel that the chiller is keeping the tank temps where I want them. I'm just wondering what, if any impact having the chiller pump and return in the same chamber may/may not be causing.

Clear as mud?

BTW, having the chiller sitting 14 feet below the tank cabinet is working like a charm!
It's keeping the heat that the chiller generates out of my living room! http://www.reefsanctuary.com/forums/images/cwmsmilies/shades.gif" alt="" />


Also, this was a copy-n-paste from the Red Sea Max forum.
Some of you may see it there as well.

You should move the feed to the chiller away from the area you return the water to. In a RSM I would return the chilled water to the display and pull from the area you are using now. Put the temp probe either in the display away from the returning chilled water or in the area you are pulling from, as long as that area is not getting chilled water placed directly in it. You want the probe to get a representative temp of the display, and it will not do that if you are flowing chilled water to the area where it is located.

That's in keeping with what I was thinking. I can, have the return pumped into the far left chamber which will, in turn, be pumped directly into the DT after being mixed with a little DT water first. It'll still be way out of reach of the temp probe and on the complete oppsite side from the chiller supply pump.

I've got this part figured out. My DT water temps, based upon the probe readings are correct. :yes:
