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.

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 Boost to switch on for an extra hour ( & BST will

water is already on, using Boost will extend the ON time by one,
