A:AnswerThe Honeywell RTH6400D1000 is a 5-1-1programmable thermostat. It has the option of programming Monday through Friday as a group of four programs, while allowing Saturday and Sunday to be programmed individually for those same four program periods.
Having the thermostat set to follow programs allows you take advantage of having it control to comfort settings while you are there and to more energy efficient settings when you are not there.
