P 02: Monday to Sunday, ON at 07:00, OFF at 12:00, ON at 14:00, OFF at 20:00. P 03: Monday to Sunday ON at 07:00, OFF at 12:00, ON at 14:00, OFF at 18:00, ON at 20:00, OFF at 22:00. P 01, P 02 or P 03 can selected by pressing the + or - buttons then pressing OK. The first ON time of the programme will be displayed. Press Menu to continue and return to normal operating mode. After P 03 it is possible to set your own programme. Using the + or - buttons press until ‘P --’ is displayed. Press OK and ‘prog 01’ is displayed. By pressing OK again it allows the first ON time to be set. Using the + or - buttons adjust the hour, then press OK. Repeat to set the minute. The arrows at the left of the display will all show. Press the + or - buttons to select one of the following options:­1-7 (Mon. - Sun.), 1-6 (Mon. - Sat.),1-5 (Mon. - Fri.), 6 & 7 (Sat. & Sun.) or any individual day until the required days are displayed. Once the required day or group of days has been selected press OK. This programmed ON time is now stored in the memory. The next option is ‘prog 02’, which is an OFF time. This is set the same way as the ON time, the day or days selection being carried forwards. When OK is pressed the OFF time is stored in the memory and ‘prog 03’ displayed. This is the next ON time. Continue programming until all selections are complete. Press MENU to return to the normal operating mode. See back page for examples. Note: Programmed ON and OFF times are set as pairs. You cannot set different days for the OFF time when compared to the ON time (i.e. if the first ON time for Monday - Friday is 07:00, the corresponding OFF time must also be set for Monday
- Friday)

The arrow will be above either the clock symbol (indicating timed output) or the hand symbol (indicating manual override)..

The Electro-Mechanical Timer allows the central heating system to be set ON or OFF every 15 minutes.
1.3.1 Three Position Switch
Using the three position switch the timer will allow either constant operation, timed operation or central heating off. Move the switch button by sliding to the desired position.
Constant: The heating will be on constantly irrespective of the
I
position of the tappets. The heating will be controlled by the main thermostat on the appliance and/or any external controls.
Timed: The heating will operate according to the position of the tappets and be controlled as above.
O
Off: No central heating. Domestic hot water will operate on demand.
1.3.2 To Set the Time of Day
Turn the timer outer bezel clockwise, to align the pointer with the correct time to the nearest 15 minutes ensuring that A.M./P.M. is considered.
Do not at any time attempt to turn the bezel anti-clockwise.
To put the clock back for winter, turn through 23hr clockwise.
1.3.3 To Set the Timed Heating Programme
Decide which times of the day the central heating is required. The heating will operate when the white tappets are set to the outer edge of the bezel. To ensure the heating stays OFF set the required tappets inwards towards the centre of the bezel. Each tappet represents 15 minutes. For example: If the heating is not required between 10 A.M. and 11 A.M. the four tappets anticlockwise from the10 A.M. will be set inwards (Fig. 4).
