Make your changes using the SET?, YES/-, and + buttons on
the programmer, found under the bottom flap.
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.
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.
DAY-TO-DAY VARIATIONS
Sometimes you might need to change the way you use your
central heating or hot water temporarily – perhaps due to an
unusually cold day, or exceptional demand for hot water.
Here’s how to do it – without affecting your program.
Switching on and off
On the front of the programmer there are two
buttons – one for central heating and one for hot water. They
allow you to switch your system either on or off, irrespective of
the program. So if the heating or hot water is off, and you want
warmth or hot water 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/hot
water 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
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/hot
water is already on, using Boost will extend the ON time by one,
two or three hours.
Press YES and you’ll see ON1, the start of your first heating peri-
od. Adjust it in 1-minute steps using the – and + buttons.
If the – and + buttons are held down, the time changes in
10-minute steps.
Press SET?, and you’ll see OFF1, the end of your first heating
period. Adjust this in the same way, press SET?, then repeat
the procedure for ON2, OFF2, ON3 and OFF3.
Set each day
If, after you’ve set OFF3 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 ON1, OFF1, ON2, OFF2, ON3 and OFF3
times in the same way.
Set each day
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?
until the programmer goes back to normal operation.

LP111Si – a 24hr program, up to 3 heating periods each day,
and every day the same.
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.

Press SET?, and you’ll see OFF1, the end of your first heating
period. Adjust this in the same way, press SET? then repeat the
