The T-stat is appropriately named. It's always "Hunting" for the proper temperature. IMO, you wasted your money on a 'wannabe' stat. Purchase a high quality stat from a pro and have him/her install it. You get greater comfort, save on operating expenses and get a full warranty. Best part is, it actually does what it's supposed to do. Never have understood DIY on systems people know little or nothing about. Too bad. Money wasted.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
