You can’t set ON1 as the last timing before midnight, but you
can set OFF3 after midnight – providing it’s not more than 23
hours and 59 minutes after ON1.
You need to set the timings in sequence – i.e. ON1, OFF1, ON2,
OFF2, ON3, OFF3. If you get out of sequence, the display will
flash a warning.

LP711Si – a 7-day program, allowing for different timings on
each day of the week, up to 3 heating periods each day.
Want to leave a timing as it is? Just press SET? and move on
to the next one.
If you need to reset your timings to the standard program and
start again, press ‘SET’ and ‘+’ together to go back to the
pre-set program.
Your system will come on for up to 3 heating periods every
24hrs. ON1 starts the first one, OFF1 finishes it, and so on.
Notice that ON2 and OFF2 are set to the same time.* This
means your system won’t respond, but if you want to activate
that middle period or change any other timings – read on.

Lifestyle
If the engineer has set your program and timings – you won’t
need to do anything else. Just keep this guide in a safe place
for future reference.
Sometimes you might need to change the way you use your
system temporarily – perhaps due to an exceptionally cold day.
Here’s how to do it – without affecting the timings in your
program.
Switching on and off
On the front of the timeswitch there is an
Advance/Boost
button.
It allows you to switch your system either on or off, irrespective of
the program. So if the heating is off, and you want warmth now,
you can either –
1. Press
Advance
to switch it on (ADV will be displayed), and it will
stay on until the end of the next period. Or if the heating is on and
you don’t need it, press Advance and it will go off until the
beginning of the next ON period.
Advance will only operate in TIMED or ONCE modes.
2. Press & Hold
Boost
to switch on for an extra hour ( & BST will
be displayed), then Press again for two ( ) or three ( ) hours.
To cancel Boost, Press Boost again ( ). Or if the heating is
already on, using Boost will extend the ON time by one, two or
three hours.
DAY-TO-DAY VARIATIONS
Over-riding the program
At the side of the display there
are four operating modes:
