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 Unit’s display (OFF sON, or OFF t ON).

One example of Program timer use might be to have the air conditioner auto- matically stop (OFF timer) after you go to sleep, then start (ON timer) automati- cally in the morning before you arise.

Use the TIMER button to select “TIMER RESET.”
