tem operates. Usage can be displayed for Today (since
12am), Yesterday, This Week (since Monday), Last
Week (last Monday through Sunday), and Total (up to
999 Hrs. 59 Min.). By monitoring your energy
usage, you see how much the set-back periods
are saving and you can test program adjustment
to save even more. Use table on page 17.

day, Yesterday, This Week, Last Week, and Total.

You can also return to normal mode at any time by
pressing RETURN.

to be 10 Hours, 26 minutes.
■ Press and hold for 3 seconds to reset the Energy

clear ALL Energy Monitor counters as well.
