Saturday, and another for Sunday, because

Fill in the times and temperatures you desire for

MORNING period. You can program DAYTIME

nails or pencil points may damage the keypad.
If at any time during programming you make an
error, just press the RUN PROGRAM key, and
continue again at the step where you left off.
