When you press SET? after OFF3 for the weekend central
heating, the display will ask ‘SET HW SAT SUN PROG?’.
Press YES, and follow the procedure.
When you press SET? after OFF3 for HW SAT SUN, the
programmer will go back to normal operation.
LP722Si – a 7-day program allowing for different timings
on each day of the week, with central heating and hot water
working independently for up to 3 heating periods each day.
If the timings haven’t been set for you, then your programmer
will still be on the factory-set standard program. This has central
heating and hot water operating together – with the option of
having different timings for each 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.
Your system will come on for up to 3 heating periods every
24hrs. ON1 starts the first period, 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, change any other timings – read on.
If, after you’ve set OFF3 for your hot water, you want to fine-tune
one or more weekdays, 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’ve finished, press SET? until you see ‘SET SAT SUN
PROG?’.
If you don’t want to alter any individual days, keep pressing
SET? until you see ‘SET SAT SUN PROG?’.
Set weekend
Press YES, and alter the central heating and hot water times in
the same way.
When you press SET? after OFF3 for HW SAT SUN, the pro-
grammer will ask the question TEST? If you want to test your
program, see below, otherwise press SET? again. If you don’t
want to test your program, press SET? again – and you’ll be
asked the question SET H’DAY? If you want to set a holiday
switch off, see page 23, otherwise press SET? again.If you’re not
going to program in a holiday switch-off, then press SET? again
and your programmer will go back to normal operation.
