Hi;
 I have been using a unit from talking thermostats the model 
number was vip 1000.  take a look at talking thermostats.com
The unit is a set back that is easily programmed my only very 
minor issue might be that the switch to go from a c to heat is 
very hard to flip.  OTHER than that the unit works great.  
Certainly is a step up from the older units that used raised 
print and clicked for every two degrees.  I can get there phone 
number if you need it.  richard
