How to use your central heating system 

Using your central heating system: 
1. TIMER: First you must set the correct time of day, then set the timer control using the tappets if it’s mechanical or buttons and display if it is electronic. There are four tappets on the clock dial, the orange tappets (shown overleaf) mean ON and the blue tappets mean OFF. Simply move the tappets to the time on the dial that you want your heating to switch ON and OFF in the 24-hour period. Remember, there will be a warm-up period from when the heating comes on up to when the property feels warm, so set the timer for about half an hour before you get out of bed, or for when you return home. It also takes time for the property to cool down again, so you can set it to go off half an hour before you go out or go to bed. 
 
2. OFF: This means OFF permanently, ignoring programmed times. 
 
3. ON or CONTINUOUS or CONSTANT: This means ON permanently, ignoring programmed times and never switching off. 
 
4. TWICE or TIMES or AUTO: This allows you to set two heating periods on the clock. Some programmers allow more than two periods, in which case this might be called ALL. 
5. ALL DAY or ONCE refers to one heating period from the first ON setting to the last OFF setting in the day, as set on the clock. This provides one long heating period as opposed to TWICE and is often useful for cold weekends. It is therefore a more expensive setting mode than the TWICE option. 
 
6. OVERRIDE or ADVANCED allows the heating to be turned on or off when there is a change to the usual heating routine but without changing the programme. The system will revert to the set programme afterwards. 
 
7. BOOST: will override the system to allow for heating or hot water to come on as an instant top-up when needed, usually for an hour or two. 
 
8. ROOM THERMOSTAT: To prevent it becoming too hot or too cold in your home, during cold weather you should keep any room thermostats set to around 21oC in the room in which you spend most of the time or 18oC in any other rooms. When the weather gets colder, increase the amount of time you have your heating on rather than turn up the thermostat. 
 
9. You may also have THERMOSTATIC RADIATOR VALVES (TRVs) fitted to your radiators. These allow you to control the heat from an individual radiator according to your needs
