About the Program timer
The PROGRAM timer allows you to integrate OFF timer and ON timer operations
in a single sequence. The sequence can involve one transition from OFF timer to
ON timer, or from ON timer to OFF timer, within a twenty-four hour period.
The first timer function to operate will be the one set nearest to the current time.
The order of operation is indicated by the arrow in the Remote Control Units
display (OFF ON, or OFF ON).

matically stop (OFF timer) after you go to sleep, then start (ON timer) automati-
cally in the morning before you arise.
