This programmer is very easy to use, I wish I could get a modern one so simple. Use the 6 white buttons along the top to move the time setting bars to the desirded on/off times. Then using the two rows of switches below decide if you want hot water or heating between the time bars.

Switch 1 is for operation between bars 1 & 2 Switch 2 is for operation between bars 2 & 3 etc but Switch 6 is for operation between time 6 and time 1 the next day. The slider switch has 3 positions Off, Auto (ie the time settings above), and On all the time Hope this helps but if you are scrapping the programmer please let me know Dec 18, 2010.
