AUTO - Timeswitch follows all programmed ‘ON’ and ‘OFF’ times.
ALL DAY - Timeswitch operates from 1st ‘ON’ time until 3rd ’OFF’, ignoring all
switching times in between.

heating during the summer without altering the programme times. Boost is still available.

Setting Time of Day and Date
Setting the On and Off Times
To alter these settings please proceed as follows:-
NB. The factory default settings for the 2nd ON/OFF times are both set at 12:00pm (midday) which cancels this ‘ON’ period giving 2 ON/OFF periods for 24hrs. If a midday ‘ON’ period is required set the 2nd ON and OFF times accordingly. If not press ENTER twice.
Once the year is set and the ENTER button is pressed the process is complete and the display will return to the run position

General Information
BATTERY
The programmer is fitted with a non-rechargeable, long life battery, which will maintain the programmed time settings for a minimum of ten months with the supply disconnected. THIS SHOULD BE SUFFICIENT TO COVER POWER INTERRUPTIONS DURING THE LIFE OF THE UNIT. During power interruptions the display will be blank, after 3 days the current time of day will be lost. These measures are to prolong the battery life.
SERVICE AND REPAIR
This programmer is NOT user serviceable. Please do not dismantle the unit. In the unlikely event of a fault developing please refer to the RESETTING THE PROGRAMMER section of this user guide shown above. If this fails to resolve the problem please contact a local heating engineer or a qualified electrician.

... an explantion for householders.
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.
The above explanation also applies to your timeswitch, which operates as a single circuit programmer.
