#1 I need a thermostat that can be programmed different everyday. Does 5-2 mean Saturday and Sunday have to be programmed together.
According to the manual for this model, 5-2 is the default setting...but it can be changed. By holding down the Menu button for 5 seconds, selecting Scheduling Options (#120), you can select among 4 possible configurations: 0=Non-Programmable. 1=Week Programmable. 2=5-2 Programming, the default setting. 3=5-1-1 Programmable. 4=7 Day Programmable.
If you were to choose option 4, you'd be able to set individual programs for every day of the week. If you chose option 3, you'd set one schedule for Monday through Friday, but separate schedules for Saturday and Sunday.
Hope that helps.
