    Energy Efficiency and the Environment
    Home energy use is responsible for more than ¼ of the total UK carbon emissions which  contribute  to  climate  change.  Heating  and  hot  water  systems  based  on boilers  account  for   of  this  figure,  so  it  is  important  to  understand  how  your controls can help to maximize energy efficiency while maintaining your comf\
    ort.
    Your Timer should be used in conjunction with appropriate temperature controls. In order to save energy the following general points should be observed:
    1.  Ensure  your  system  contains  a  room  thermostat  and  a  hot  water  thermostat, and  that  both  are  set  to  appropriate  temperature  levels:  typically  20°C  for  the room temperature and between 55 - 60°C for the hot water temperature.
    2. Programme your heating and hot water to be off when you are not in the house. If you  are  concerned  about  possible  frost  damage  to  any  exposed  pipe  work,  it  is advisable to fit a frost protection system – your installer can advise you about this.
    3.  Think  about  how  you  use  your  domestic  hot  water  –  if  you  have  a  storage system, it is not necessary to have this switched on all the time, even when you are in the house.
    4.  Consider  the  heat  up  times  required  for  your  central  heating.  Every  home responds  differently  when  the  heating  is  switched  on.  Adjust  the  start  time  so that you are not cold when you get up in the morning. A shorter heat up time is required for other heating periods.
    5.  In  the  evening,  when  the  house  is  up  to  temperature,  it  is  often  possible  to switch off the heating up to an hour before you go to bed, without any noticeable reduction in comfort.

    WHAT IS A PROGRAMMER?
    ...an Explanation for Householders (as recommended by the Energy Savings Trust)
    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.

    WHAT IS A TI mer?
    General Description
    Your  Honeywell  ST9100S  provides  timing  control  for  your  central  heating  system, letting you set ON and OFF periods to suit your own lifestyle. 
    The ST9100S does not directly control the temperature but works together with other temperature  controls,  such  as  room  thermostats,  to  control  your  heating  system  in your home.
    ST9100S has 1-day programming and 2 on/off periods per day, making it very simple to use.
    ST9100S also has a Boiler Service  r eminder / Shut-down feature, which helps ensure your gas boiler is regularly serviced in compliance with UK Gas Safety regulations. For more details see pages 16, 17.
    The following instructions explain how to programme and use the ST9100S to provide the most home comfort at the least cost.
    The way to use a Timer
    Think about the time periods when you are typically in the house and when you are not. These are the times you should use as the basis for the programmes. It will be necessary  to  allow  some  heat-up  time  for  the  heating  system  after  periods  when  it has  been  off  –  this  would  typically  be  1  -  1½  hours,  depending  on  your  house  and your preferences.
    Other  features  are  commonly  available  on  the Timer  to  enhance  comfort  and convenience, for example, OV err ID e, eXT r A HOU r, and mOD e buttons.
    A  typical  use  of  the OVerr ID e  feature  is  when  you  return  home  unexpectedly  for the rest of the day and the heating is off. Just press the OVerr ID e button and the heating  will  come  on  until  the  next  programme  time,  at  which  point  it  will  follow  the normal  programme.  The  advantage  here  is  that  you  do  not  have  to  remember  to switch off because the normal time programme does this for you.
    A typical use of the eXT r A HOU r button would be if you returned to the house for a short period when t he heating was off. Pressing the eXT r A HOU r button gives you 1, 2, or 3 hours of heating, exactly when you need it. Another typical use is when the heating is already on and you want it to stay on a little longer - just press eXT r A HOUr and, for that day only, an hour will be added to the end of the time at which heating normally goes off.
    The mOD e  button  allows  you  to  select  how  you  want  to  operate  your  heating.  The most obvious use is to switch heating OFF during the summer months, but you may also use this feature if you take a mid-week day off work, you can then set the mOD e to ONCe to keep the system ON during the day from the first programmed ON time till the last programmed OFF time. 
    						
    							
    
    
    Your ST9100S should have been set up to work correctly when it was installed. However, the following will show you how you can modify your settings to meet your particular lifestyle.
    To  assist  you  with  programming  and  everyday  use  your  ST9100S  will  display  text messages at every stage to help you get the most out of your central heating system. The  ST9100S  uses  LoT™  Technology  to  constantly  update  the  display  to  give  you feedback about what is required.
    Step 1: Setting the Date & Time
    Your  ST9100S  had  the  date  and  time  set  at  the  factory,  and  these  are  normally maintained by a backup battery in the event of power failures. If you wish to change the date or time, or if the LoT™ Display shows the message ‘SET DATE + TIME’ just follow the instructions below. Otherwise, go to Step 2.
    a. Move the slider to the DAY/TI me position. The message ‘SET DATE + TIME’ will show briefly on the screen, followed by ‘SET THE DAY’, and the day of the month will now be flashing to indicate it can be changed.
    b. To change the day of the month, press the   or  buttons until the correct day is shown.  Each press of the button will change the date by one day. As soon as a change has been made, the message ‘IS DAY OK?’ will be displayed. Once the  correct  day  is  reached,  press  the  green   button  to  confirm,  and  move  to the  next  step.  If  you  do  not  need  to  make  a  change,  just  press  the   button immediately and this will move you to the next step.
    c.  The month digits will now be flashing and ‘SET THE MONTH’ will be displayed. To change the month, press the   or  buttons until the correct month is shown. The  message  ‘IS  MONTH  OK?’  will  be  displayed.  Press  the  green   button  to confirm the month is correct, and move to the next step.

    d. The  year  digits  will  now  be  flashing  and  ‘SET  THE  YEAR’  will  be  displayed.  To change the year, press the   or  buttons until the correct year is shown. The message ‘IS YEAR OK?’ will be displayed. Press the green  button to confirm the year is correct. If you have made a change, and the date is a valid date, the message ‘DATE SAVED’ will show, and you can move to the next step. If the date you  set  was  not  valid,  for  example  31  September,  the  message  ‘INVALID’  will show and you will be returned to the start of the date setting operation.
    e.  The time will now be flashing and the message ‘SET THE TIME’ will be displayed. To change the time, press the   or  buttons until the correct time is shown. Each press of the button will change the time by one minute. Holding the button down  for  more  than  a  few  seconds  will  change  the  time  slowly  at  first,  then quickly. The message ‘IS TIME OK?’ will be displayed. Press the green  button to confirm the time is correct.  If you have made a change, the message ‘TIME SAVED’ will show, followed quickly by ‘DATE + TIME COMPLETE’.
    f.  Move the slider to the rUN position, to complete setting the date and time.
    Note:  if  the  slider  is  moved  at  any  time  before  the  date  and  time  have  been  set correctly,  the  message  ‘DATE  UNCHANGED’  will  be  displayed  briefly,  and  your changes will not be saved.
    Step 2: Running a Built-in Programme
    With  the  date  and  time  correct,  your  ST9100S  Timer  will  now  be  operating  to  the built-in  programme.  This  has  been  designed  to  provide  heating  at  typical  times throughout  the  day,  but  if  you  want  to  customise  the  settings,  please  see  the  next section ‘Pr OG r A mm ING YOU r  ST9100S’ (page 6).

    The Built-in Programmes
    The  built-in  programmes  give  you  a  starting  point  that  you  can  personalise  to  your own  requirements.  Your  Installer  should  have  selected  one  and  ticked  the  box alongside it. If there is no tick, the product normally leaves the factory with Profile A installed, but it is a simple matter to select one of the other profiles (see Changing the Installer Parameters, page 12).
    Your Personal Programme
    The table below has been left blank for you to record your own personal programme. For ease of use, your ST9100S is supplied as standard with only 2 on/off’s enabled. To enable ON/OFF period 3 see Fine Tuning your ST9100S (page 12).

    reviewing the Programme Times
    To review your programme, move the slider to the Pr OG r A mme position.
    To  review  the  programme  times,  press  the   button  repeatedly.  The  appropriate ON  and OFF  markers  will  be  displayed  to  show  you  which  time  is  being  reviewed. Any  of  these  times  can  be  adjusted  by  using  the    or   buttons,  and  then confirmed  using  the   button.  Remember  to  return  the  slider  to  the rUN  position after reviewing is complete.
    m odifying the Programme
    The programme has two pairs of ON/OFF switching times per day. Each time can be set between 3.00 am and 2.50 am (on the next day) to allow you to programme the system to stay on past midnight, if required. 
    a. Move  the  slider  to  the Pr OG r A mme  position.  ‘SET  PROGRAMME’  will  show briefly to verify this action.
    b. ‘SET ON-TIME 1’ will then be displayed and the time setting for the first ON 1 time will now be flashing to indicate it can be changed. If you do not wish to change the time, press the green  button and move to the next step. If you do wish to make a change, use the   or  buttons to change the first ON 1 time. Each press of the button will change the time by 10 minutes. As soon as the time has been changed, the message ‘ON-TIME 1 OK?’ will be displayed. Press the green  button to confirm the time is correct and move to the next step. ‘SAVED’ will be displayed for a moment to confirm that any change has been saved to memory.

    Note:  When  pressing  the   button  the  next ON  or OFF  marker  may  start  to  flash. This indicates you have tried to set a time equal to one of the next programme times already  in  the  memory.    Similarly,  when  pressing  the   button  the  previous ON  or OFF  marker  may  start  to  flash.  This  indicates  you  have  tried  to  set  a  time  equal  to one  of  the  previous  programme  times.  If  this  happens  the  ST9100S  simply  moves both times together as long as you continue to press the   or  buttons.  Follow the procedure in ‘reviewing the Programme Times’ (page 7) to check and adjust these times as necessary.
    c.  ‘SET OFF-TIME 1’ will be displayed and the first OFF 1 time will now be flashing. If you do not wish to change the time, press the green  button and move to the next step. Otherwise, use the   or  buttons to change the time. Press the green  button to confirm the time is correct and move to the next step. ‘SAVED’ will  be  displayed  for  a  moment  to  confirm  that  any  change  has  been  saved  to memory.
    d. The remaining ON and OFF times (ON 2, OFF 2) can be set by using the   or   buttons  to  change  the  time,  and  the  green   button  to  confirm  the  time is correct and move to the next step. If you do not wish to change the time, just press  the  green   button  to  move  directly  to  the  next ON/OFF  time  without making any changes.
    e.  After setting or reviewing the last off time, OFF 2, the message ‘COMPLETE’ will be displayed to indicate the times have been set.
