What temperature do you keep your house in the winter?

We live close to Gillette stadium where the New England Patriots play their home games in Foxboro, Massachusetts.

Our upstairs heat pump is set to 60/62 degrees, downstairs we have two heat pumps (1-ton and 1.5 ton) and the 1.5 ton is set to 70 degrees and the 1-ton is set to 62/64 degrees. 1840 square foot cape style house built in the late 1970's.

My Sanyos were working down to 3.5 F, but there were many defrost cycles.
The power use was high too. We shut them down and went to back-up heat.
When it got up to 10F yesterday, I said "Summer again!" and turned them back on!

How well did those Fujitsu units work while it was down around zero?
Did they maintain 65F the whole time it was down in the zero range?
