Reading some of the System Reviews from GeoDean's System reviews thread, I see that a lot of people keep there systems set higher than mine Temperature wise. I am curious what people have there systems set at.

In the Winter I have mine set at 68 F degrees, I may lower it to 66 F if I feel hot or as high as 70 F when I'm cold. I experimented with setbacks with my last system, but I didn't see any significant savings, so I just leave it set at one Temperature now.

In the Summer I generally keep it at 70 to 72 degrees, the wife likes it cool, so If I'm cold I'm wearing a sweater inside the house when it's 95 degrees outside.

TG,
70 winter, 75 summer.

We keep ours at 70 year round.

Tech, we just had our geo installed few weeks ago. I am from New Jersey too (North). We keep our thermostat at 67 upstairs and 68 downstairs. This seems to be comfortable to us. We set it to 70 before but I find it too warm in the middle of the night. We haven't got our bill yet and hopefully we can see a significant reduction compare to last year. (Cost us about $2000 on oil).

68F in the fall, 69F late fall then 70F into winter and I bump it up to 71F if there's a cold snap predicted so that the thermal mass of the house can store some heat before the aux kicks in. In the summer it's set at 70F or 71F. The thermostat is downstairs where the rooms don't get much sun (and hence don't get so hot in summer). To get it cool upstairs I need the thermostat lower than the temperature I actually want it upstairs. I guess I could get a remote sensor and locate that upstairs for summer but I find just having it a couple of degrees lower downstairs is not a big deal. With the thermostat at 70F downstairs the bedrooms are around 72-74F (depending if I have the blower on all the time or not). I experimented with setbacks but, as I work from home, determined it's barely worth it - even if I'm away at the weekend. It's an old high-thermal mass house so I figure it's better to keep everything at a constant temperature rather than constantly ramping up and down. It's funny, though, 70F in the winter feels toasty warm whereas 70F in the summer feels somewhat chilly!

Ours is to warm, with the kids we keep the house at 73 in winter and 75 in summer. To warm for me, but I often find the kids with no blankets on and cold at night, our oldest (6) finally has learned to cover himself back up when he is cold.

I keep at 68, but my wife sets for 72+

We operate a low-tech "spousal set-back, set-up program"

I guess I'm the only pushover here.  We keep ours at 63 here in upstate NY (when we had oil we kept it 58-60).  We still haven't used it for summer.  We keep the upstairs zone at 60, but the temp stays at about 64 up there.  When I moved here from California I was told that people in the northeast keep it cool, but I have been learning that may not be the case. 

The short answer to the "where do you set it" question is always wherever mom is comfortable. You've spent the money on geo and are saving thousands/yr. Now be comfortable.
The city of Ann Arbor in MI boasts raising the thermostat in city hall to save taxpayer money in the summer, yet there are individual fans at thousands of desks.
I'm always most impressed by comfortable temperatures at the lowest possible cost not loosely bearable temps at lower costs.

The Comfort zone is different for different people. Just because someone is from Northern Canada or Panama doesn't mean they can be comforable in the cold or heat better than other people. 63 degrees would be much more expensive for me when the wife has me served with divorce papers.  :)  I know people in the Northeast who walk around in sweaters all day to save on the heating bill, and others that have t-shirts on inside all the time in the winter. (They keep there house at 75, with a natural gas system)    

For me personally, 68 requires me to have Fleece sweaters on all the time and sometimes I'm still cold.

Mine 60 house empty, 68 occupied, 66 sleeping . try to maintain 40% RH and with that these temps are down right toasty

Summer 74 occupied , 78 empty , 70 sleeping

We keep ours on 73 or 74 all year around.

In the winer the occupied zone is 66 to 68 depending on metabolism at the time.  63 for sleeping.  Unoccupied zone 63.  I guess the unoccupied 63 is for energy considerations, all the rest are comfort.

In the summer the windows are open until / unless house exceeds 75 and is expected to stay there through the night.  Then closed up and set at 72ish.
