    You can find a manual damper that can be controled from in the room,search the net.

You add a lot of air to counteract the heat from computers during the cooling season and the damper closes if no heat is needed in the room during the winter time. Duct modifications are definitely needed, but it works like a champ for situations just like this.

    Wow. That sounds EXACTLY like what I need. Thanks a lot. I will research a little more and then talk w/ a pro about getting it done. Thanks again!!!

    Understand that will solve the overheating,but not the undercooling,without duct changes,and maybe not even with changes.

    You will need to increase the size of the duct(s) feeding that room for it to work to add more cooling.

    The room cools perfectly in the summer. The only problem is that it gets too hot in the winter. Sure sounds like the slave solution is the best one, but would be more work/cost that the manual damper solution.

    As for dampers that can be controlled in the room, are you referring to the dampers built into the grill? If so, my experience has been that when I partially close them, they become noisy (wind whistling through the grate). I am hoping you are referring to something different, but did not find anything doing a cursory search of the net. A link would be greatly appreciated.

    I found the damper you mentioned and talked w/ my contractor about installing it. Alternatively, he suggested that I go w/ a low-voltage motorized damper that can be controlled w/ a switch/knob that will be in the "hot" room. Anyone have thoughts or experience w/ these?

    If i was you i would ask him to set it up with a thermostat so you can atleast keep control over your temp in the winter.

    Yes and it works well in rooms that the btu's needed, change on an hourly, daily, weekly, or even seasonably.We use t-stats only for control to prevent human error(forget to turn on/off and equipment overheats.).Most of our zone/equipment room installs require equipment not to overheat, using the existing a/c. DO NOT ATTEMPT ON YOUR ON. Found a qualified contractor and one who has installed zone systems prior.

    Thanks for all the info. I am going w/ the themostat controlled slave solution (w/ the motorized damper). Pro will be installing as soon as the parts arrive.

    Thanks again.

    Let us know how it works. When you reply, most contributors will get an e-mail even if it's months later.

    I think the slave zone system proposed doesn't actually turn the system on. If not, and if you find later that you want that ability, I just came across this. It might be useful.

    Just got the quote from my HVAC pro on the motorized dampers (w/ themostat control) and it proved to be cost prohibitive I asked him to work up a price on the cable controlled options. We'll see where that takes me.
