The day will show as the yellow arrow shows. Dimplex set Sunday is 1 and Saturday is 7.

The bottom part of the screens shows a square - one hour is one square and runs from 00 - 23.

Press the plus and minus buttons depending if your want the heating / tank on or off. For example if you wanted it off you would press the minus button. If you got to a time you wanted it on you would press the up arrow. In the picture you will see squares above, this means the heat / tank will come on that time.

Press ok when you are happy and repeat for each day. When you have finished you will be back to the zone selection screen.
