Independent 7-day Programmes let you choose settings built into ST9500C for each

day of the week to match your lifestyle, while maximising energy savings, or alter them

to your personal settings.

Automatic Summer/Winter Time Change will adjust the clock forward and backward

automatically when the clocks change, saving you having to change your ST9500C

every time.

Built-in Memory holds your programme indeﬁ nitely - even if the mains power fails.

Energy Efﬁ ciency and the Environment

Home energy use is responsible for more than ¼ of the total UK carbon emissions

which contribute to climate change. Heating and hot water systems based on

boilers account for of this ﬁ gure, so it is important to understand how your

controls can help to maximize energy efﬁ ciency while maintaining your comfort.

Your Programmer should be used in conjunction with appropriate temperature

controls. In order to save energy the following general points should be observed:

1. Ensure your system contains a room thermostat and a hot water thermostat (if

you have stored hot water), and that both are set to appropriate temperature

levels: typically 20°C for the room temperature and between 55 - 60°C for the

hot water temperature.

2. Programme your heating and hot water to be off when you are not in the house.

If you are concerned about possible frost damage to any exposed pipe work, it

is advisable to ﬁ t a frost protection system – your installer can advise you about

this.

3. Think about how you use your domestic hot water – if you have a storage

system, it is not necessary to have this switched on all the time, even when you

are in the house.

4. Consider the heat up times required for your central heating. Every home

responds differently when the heating is switched on. Adjust the start time so

that you are not cold when you get up in the morning. A shorter heat up time is

required for other heating periods.

5. In the evening, when the house is up to temperature, it is often possible to

switch off the heating up to an hour before you go to bed, without any noticeable

reduction in comfort.

WHAT IS A PROGRAMMER?

...an Explanation for Householders

(as recommended by the Energy Savings Trust)

Programmers allow you to set ‘On’ and ‘Off’ time periods. Some models switch the central heating

and domestic hot water on and off at the same time, while others allow the domestic hot water

and heating to come on and go off at different times. Set the ‘On’ and ‘Off’ time periods to suit

your own lifestyle. On some programmers you must also set whether you want the heating and hot

water to run continuously, run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently

off. The time on the programmer must be correct. Some types have to be adjusted in spring and

autumn at the changes between Greenwich Mean Time and British

Summer Time. You may be able to temporarily adjust the heating

programme, for example, ‘Override’, ‘Advance’, or ‘Boost’. These

are explained in the manufacturer’s instructions. The heating will

not work if the room thermostat has switched the heating off. And,

if you have a hot-water cylinder, the water heating will not work if

the cylinder thermostat detects that the hot water has reached the

correct temperature.
