LP522Si – a 5/2-day program allowing for different
timings at the weekends, 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 means
that central heating and hot water will operate together, with
the same timings for weekdays and different ones for the
weekend. 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, or change any other timings – read on.
