    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 Programmer 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 room thermostats in 2 seperate zones, and that 
    both are set to appropriate temperature levels: typically 20°C for the main 
    occupied zone and 18°C for the less occupied zone (typically the bed\
    rooms). 
    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 stora\
    ge 
    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 heatin\
    g 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 t\
    o 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 ROOM THERMOSTAT?
    ...an explanation for Householders (as recommended by the Energy Savings Trust)A room thermostat simply switches the heating system on and off as necessary. It works by sensing 
    the air temperature, switching on the heating when the air temperature falls below the thermostat 
    setting, and switching it off once this set temperature has been reached. Turning a room thermostat to 
    a higher setting will not make the room heat up any faster. How quickly the room heats up depends on 
    the design of the heating system, for example, the size of boiler and ra\
    diators. Neither does the setting 
    affect how quickly the room cools down. Turning a room thermostat to a lower setting will result in the 
    room being controlled at a lower temperature, and saves energy. The heating system will not work if 
    a time switch or programmer has switched it off. The way to set and use your room thermostat is to 
    find the lowest temperature setting that you are comfortable with, and then leave it alone to do its job. 
    The best way to do this is to set the room thermostat to a low temperature – say 18ºC – and then turn 
    it up by one degree each day until you are comfortable with the temperature. You won’t have to adjust 
    the thermostat further. Any adjustment above this setting will waste energy and cost you more money.
    If your heating system is a boiler with radiators, there will usually be only one room thermostat to 
    control the whole house. But you can have different temperatures in individual rooms by installing 
    thermostatic radiator valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose 
    a temperature that is reasonable for the whole house. If you do have TRVs, you can choose a slightly 
    higher setting to make sure that even the coldest room is comfortable, then prevent any overheating 
    in other rooms by adjusting the TRVs.
    Room thermostats need a free flow of air to sense the temperature, so they must not be covered by 
    curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may prevent the 
    thermostat from working properly.

    General Description of Controls in Your System
    Your Honeywell ST9520C provides timing control for both zones in your central 
    heating system, letting you set ON and OFF periods to suit your own lifestyle. 
    The ST9520C 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.
    With 7-day programming and up to 3 on/off periods per day, every day can be set 
    differently, and both heating zones can be set at different times from each other.
    ST9520C also has a Boiler Service reminder / Shut-down feature, which helps 
    ensure your gas boiler is regularly serviced in compliance with UK Gas Safety 
    Regulations. For more details see pages 18 & 19.
    Your system includes DT92E wireless room thermostats and may include a BDR91T 
    Relay Box to switch your boiler remotely. These products use state of the art 2 way 
    RF communications to share information and give you robust and flexible control of 
    your indoor environment.
    The following instructions explain how to programme and use the ST9520C, and 
    associated controls, to provide the most home comfort at the least cost.
    The way to use a Programmer
    Think about the time periods when you are typically in the house and when you are 
    not, and also the times when you occupy each of the zones. 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.
    If Optimum Start has been selected (see page 17), you do not have to allow for this 
    heat up time as the Programmer is intelligent and will calculate the correct starting 
    time for your house. This is based on measurements it makes about your system 
    characteristics, and on the current and target room temperatures. All you have to do 
    is programme the time periods when you want to be comfortable.
    Other features are commonly available on the Programmer to enhance comfort and 
    convenience, for example, OVERRIDE, EXTRA HOUR, and MODE buttons.
    A typical use of the OVERRIDE feature is when you return home unexpectedly for 
    the rest of the day and the heating is off. Just press the zone OVERRIDE button and 
    the heating will come on in that zone 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.
    CONTROL OF YOUR SYSTEM 
    						
    							5
    A typical use of the EXTRA HOUR button would be if you returned to the house for 
    a short period when the heating was off. Pressing the appropriate EXTRA HOUR 
    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  EXTRA HOUR and, for that day only, an hour will be added to the end of the 
    time at which heating normally goes off.
    The  MODE buttons allow you to select how you want to operate the heating in each\
     
    zone  independently . 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 MODE to ONCE to keep the system ON during the day 
    from the first programmed ON time till the last programmed OFF time.
    The way to use a Room Thermostat
    The way to set and use your room thermostat is to find the lowest temperature setting 
    that you are comfortable with, and then leave it alone to do its job. The best way to do 
    this is to set the room thermostat to a low temperature – say 18°C – and then turn it 
    up by one degree each day until you are comfortable with the temperature. You won’t 
    have to adjust the thermostat further. Any adjustment above this setting will waste 
    energy and cost you more money.
    DT92E has a green ECO button, which enables you to set a period of time at a lower 
    temperature. This energy saving feature is most useful if you are out of the house 
    for a few hours, or if you want a reduced temperature for a while and don’t want to 
    have to remember to turn the temperature back up (see pages 22 & 23 for details).
    Control of Your Boiler
    There are several ways your boiler may be controlled. It may be switched directly 
    using the ST9520C timer. If installed in a remote location, it may be switched using a 
    BDR91T relay box. If your boiler supports the OpenTherm communications system, 
    it may be connected to the ST9520C timer by OpenTherm wiring, over which the 
    control information is sent.
    In each situation the operation of the boiler is determined automatically by the 
    combination of inputs from the room thermostat and the timer, and in such a way as 
    to maintain your comfort with minimal energy use. The timer will indicate the on/off 
    status of the boiler by showing the flame symbol 
    .
    Optimisation (see page 17 for explanatory diagrams)
    Your control system has some features called Optimisation, which aim to save 
    energy while making you as comfortable as possible. These may or may not be 
    enabled – check page 34 where your Installer should have indicated how these 
    were set. Optimisation does not apply to your Hot Water, only to your Heating.
    CONTROL OF YOUR SYSTEM

    Your ST9520C 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 ST9520C will display text 
    messages at every stage to help you get the most out of your central heating system. 
    The ST9520C uses LoT™ Technology to constantly update the display to give you 
    feedback about what is required.
    Step 1: Setting the Date & Time
    Your ST9520C 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 DA\
    TE + TIME’ just 
    follow the instructions below. Otherwise, go to Step 2.
    a. Move the slider to the DAY/TIME 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.

    Optimum Start works by measuring how quickly your system normally heats up, and 
    using this to calculate the correct time to switch on to reach your comfort temperature, 
    when you want it. So the times you set are when you want the heating to be at 
    the correct temperature, and the system adjusts the starting time to meet this.
    Delayed Start is an alternative to Optimum Start. It works by using your normal 
    programmed start times, compares the actual temperature with the set temperature, and 
    delays the start a little depending on how close these temperatures are to each other.
    Optimum Stop saves energy, and money, by switching off a little earlier than the 
    normal programme time. If the house is up to temperature, you will not notice the 
    effect on the temperature, but you will see a difference in your fuel bill.
    The radiator symbols on ST9520C will flash to let you know whenever Op\
    timisation 
    is operating in each zone. 
    The other controls in your system should not require adjustment.

    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 ST9520C Programmer will now be operating to 
    the built-in programmes. These have been designed to provide heating at typical 
    times throughout the day, but if you want to customise the settings, please see the 
    next section ‘PROGRAMMING YOUR  ST9520C’ (page 8).

    PROGRAMMING YOUR  ST9520C
    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 15).

    PROGRAMMING YOUR  ST9520C
    Reviewing the Programme Times
    To review your zone 1 programme, move the slider to the ZONE 1 position. 
    To review your zone 2 programme, move the slider to the ZONE 2 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.
    Modifying the Zone 1 Programme
    The zone 1 programme has three 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 zone to stay on past midnight, if required. 
    a.  Move the slider to the  ZONE 1 position. ‘SET ZONE 1’ will show briefly to verify 
    this action.
    b.  ‘SET ON-TIME 1’ will then be displayed and the time setting for th\
    e first ON 1 
    time for MONDAY 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 ST9520C simply moves 
    both times together as long as you continue to press the 
      or  buttons.  Follow 
    the procedure in ‘Reviewing the Programme Times’ (page 9) 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, ON 3, OFF 3) can be set by 
    using the   or  buttons to change the time then 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 3, the message ‘COMPLETE’ will 
    be displayed to indicate the times for Monday have been set.
    You now have a choice of how to set the programme for the next day:
    Copying One Day’s Programme to Another Day (example Monday to Tuesday):
    f.   Whilst the day is showing Monday, Press the COPY DAY button. The message 
    ‘COPY MON TO TUESDAY OK?’ will be displayed and the letters TUE will flash 
    to indicate the programme for Monday can be copied to Tuesday.
    g.  To select a different day to copy to, press the NEXT DAY button to cycle through 
    the days. With each press of the NEXT DAY button the message will change to 
    indicate the new day you are copying to.
    h.  When the required day is indicated, press the green 
     button to confirm, and 
    the message ‘MON COPIED’ will be displayed for a moment. The day i\
    nto which 
    Mondays programme has been copied is now available to have its programme 
    edited.
    Note:  Once a day’s programme has been confirmed in this way, it now becomes the 
    day whose programme is copied if the COPY DAY button is pressed again.
    OR
    Programming a Different Day:
    i.  Press the NEXT DAY button to select the next day, which is displayed along the 
    top of the screen.  The programme for that day can then be adjusted by following 
    steps  b – e above.  Programmes for the remaining days can be set in the same 
    way, using the NEXT DAY button to move to the next day.
