The thermostat that we purchased was a good change to our heating/cooling system, but we still have some problems. It can be 77°F in the office and 67°F in the master bedroom.
Since our house is less than 1600 square feet, this is surprising.
I did some looking on the internet and found this project on source-forge:
The DIY Zoning Project.
This project is one person's way of dealing with the situation that I see in my home.
Sounds like an interesting project - I may start experimenting.
