It is also important to follow all instructions related to the wiring diagram as it can differ between different systems. For example, some diagrams may require specialist tools such as a digital amp meter to complete the wiring process properly. G = a gravity-fed hot water system – which does not allow independent setting of heating without hot water, though hot water can be controlled alone. 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 on the standard program ON2 and OFF2 are set to the same time for both central heating and hot water. * This means your system won’t respond, but if you want to activate that middle period, or change any other timings – read on. 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. Press SET?, and you’ll see OFF1, the end of your first central heating period. Adjust this in the same way, press SET?, then repeat the procedure for ON2, OFF2, ON3 and OFF3.

If the engineer hasn’t set your timings for you, your timeswitch will work with a standard program that has been set at the factory. If this doesn’t suit you, it’s very easy to change it – when you’ve read this introductory section, simply turn to The wiring diagram also includes two terminals, one positive and one negative, which connect the rest of the system to a 230V AC power supply. Lastly, the diagram debuts two time and temperature programmers that control when the heating will come on and off and the desired temperature. If the timings haven’t been set for you, then your programmer will still be on the factory-set standard 24hr program, with central heating and hot water operating together on the same settings for every day of the week. But it’s easy to make changes – just follow the instructions. To further simplify the process of interpreting the wiring diagram, most diagrams also have arrows indicating which wire from each component should be attached to the power source. This also helps to ensure that all components of the system are securely connected. 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.

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. If the engineer hasn’t set your timings for you, your programmer will work with a standard program that has been set at the factory. If this doesn’t suit you, it’s very easy to change it – when you’ve read this introductory section, simply go to the section that contains your programmer model. The wiring diagram for the Drayton Lifestyle LP112 includes nine different components, each connected with at least one other component. By understanding the layout of these components and what they do, you can ensure that your heating system runs smoothly and efficiently. Setting times for central heating and hot water to switch on and off can help reduce your home's energy consumption. LP241 – a 24hr program, with central heating and hot water working independently for up to 3 heating periods each day, and every day the same.

When you press SET? after setting OFF3 for the central heating, the display will ask ‘SET HW PROG?’.

one for central heating and one for hot water. They allow you to switch either on or off, irrespective of the program. So if the heating is off, and you want warmth now – press Advance to switch it on, and it will stay on until the end of the next OFF period. Or if the 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. First you set the times that are going to be the same for each weekday, then you can select each day individually and make any further adjustments. If you want each day to be quite different, go straight to ‘Set each day’. LP112 – a 24hr program, with linked central heating and hot water on for up to 3 heating periods each day, and every day the same.
