Hello there! I'm Norman but you can call me Norm. Let's see what I can do to get you some answers today. I'm ready to get started whenever you are.
A general rule of thumb is that energy savings can be 2% to 4% for every 1 degree difference in thermostat set-point; either raising the cooling setpoint or lowering the heating set-point. That would be for a 24 hour period.
To estimate the savings from set-points during unoccupied periods; prorate the percentage based on the number of hours of set-back / set-up.
Here's an example, if you are raising the cooling temp by 10 degrees for a 12 -hour period, estimated savings can be between 10% and 20%.
That can be calculated like: 2% to 4% per degree * 10 degrees * (12 hours/24 hours) = 10% to 20% savings
However, these estimates are just percentages of your electrical specifically used for heating and cooling. This is not a percentage of your total electric bill.
Also, actual savings will depend on your specific climate zone. Savings as a percentage of your heating and cooling bill will be greater in mild climates than in higher/harsher climates.

If you have more questions and you reply to this post it may take me awhile to respond. I will try to check back once in awhile but glitches in the chat system do not allow for notifications of chat replies.
Does that answer all of your questions for today?
