How do I set the timer on my Saunier Duval 23 boiler?

This is from the manual...you can download it from the device manuals website (it works in the UK).


Note. The timeclock can be set to give a minimum
of one and a maximum of three "On" and "Off"
times.
Place the slide switch to "C1". Press the "Enter"
button. The display will show the first "On" time.
Using the plus and minus buttons, change the first
"On" time to the time you require. Press the "Enter"
button twice. This stores the new time and shows
it to confirm it has been stored in the timeclock
memory.
Press the "Enter" button again. The display will
show the first "Off" time.
Using the plus and minus button, change the first
"Off" time to the time you require. Press the "Enter"
button twice. The display will show the first "On"
time. Press the "Enter" button again. The display
will now show the first "Off" time you have just
entered.
Repeat the above for the remaining "On" and "Off"
times.
When you have set the "On" and "Off" times you
require, place the slide switch to "Auto".
Note. If you do not want to set all three "On" and
"Off" times, follow the above instructions, but, after
you have set the times you require, set the other
times to show a series of dashes. The series of dashes are between times 23.59 and 0.00.
