If, after you’ve set OFF3 for both SAT & SUN, you want to fine-
tune Saturday or Sunday, press SET? until you find the first day
you want to adjust – then go through the procedure, altering any
time you wish. Press SET? to move on to the next day. When
you press SET? after setting your hot water for Sundays, the pro-
grammer will go back to normal operation.
If you don’t want to alter either day, keep pressing SET?

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.
Lifestyle Programmers will automatically switch your central
heating and hot water on and off at times that suit you.
Depending on your system, central heating and hot water
can either both come on and off at the same time, or work
independently. The light on the front of the programmer
shows when each one is on.
Over-riding the program
LP241Si – a 24hr program, with central heating and hot water
working independently for up to 3 heating periods each day,
and every day the same.
If the timings haven’t been set for you, then your programmer
will still be on the factory-set standard 24hr program, with
central heating and hot water operating together on the
same timings for every day of the week. But it’s easy to make
changes, and have heating and water working independently
– just follow the instructions.
Want to leave a timing as it is? 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.
If you don’t press anything for two minutes, the programmer
automatically goes back to normal operation.

which you can return to by selecting TIMED.
