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 can temporarily adjust the heating programme, for example by using the features, ‘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 hotwater cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature. Allowing different programmes for weekdays and weekends, and independent timing of each channel. LP522 provides the ability to control central heating even more efficiently. No longer do systems have to switch on as early at weekends as they do on weekdays.
