General Description Your Honeywell ST9500C provides timing control for 2 zones within your central heating system, letting you set ON and OFF periods to suit your own lifestyle. The ST9500C 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. It is common to set the living area as zone 1, and the bedroom area as zone 2. With 7-day programming and up to 3 on/off periods per day, every day can be set differently, and each zone can be set to come on at different times from each other. The following instructions explain how to programme and use the ST9500C 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 are in each zone. 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 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 OVERRIDE 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 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 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. GETTING STARTED WITH YOUR ST9500C Your ST9500C 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 ST9500C will display text messages at every stage to help you get the most out of your central heating system. The ST9500C uses LoT™ Technology to constantly update the display to give you feedback about what is required. Step 1: Setting the Date & Time Your ST9500C 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/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. ZONE 1 ZONE 2 DAY/TIME ZONE 1 ZONE 2 RUN 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. GETTING STARTED WITH YOUR ST9500C 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 ST9500C Programmer will now be operating to the built-in programmes. These have been designed to provide heating in each zone at typical times throughout the day, but if you want to customise the settings, please see the next section ‘PROGRAMMING YOUR ST9500C’ (page 6). PROGRAMMING YOUR ST9500C 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).

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 zone 1 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. ZONE 1 ZONE 2 DAY/TIME ZONE 1 ZONE 2 RUN b. ‘SET ON-TIME 1’ will then be displayed and the time setting for the 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. ZONE 1 ZONE 2 ZONE 1 ZONE 2 PROGRAMMING YOUR ST9500C 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 ST9500C 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, ON 3, OFF 3) 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 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 into 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. PROGRAMMING YOUR ST9500C Exiting ZONE 1 Programming Mode: To exit ZONE 1 programming mode, move the slider to the RUN position. This can be done at any time during the programming process, and any changes made and confirmed with the button will have been saved.

Press a button to finish programming, or move the slider to the RUN position. Disabling / Enabling Time Periods (for Zone 1 and/or Zone 2) To disable any of the time periods ON 1 to OFF 1, ON 2 to OFF 2, or ON 3 to OFF 3, simply set the ON time and its paired OFF time to the same time, and the programme will just ignore them. To re-enable the time period, simply set the two ON and OFF times to be different. OPERATING YOUR ST9500C Choosing the Operating Mode (for Zone 1 and/or Zone 2) The operating mode may only be changed when the slider is set to the RUN position. DAY/TIME A green INDICATOR LAMP shows when zone 1 or zone 2 is switched ON. ZONE 2 Two MODE buttons are provided to select the Operating Mode and therefore how the zones are controlled. ZONE 1 RUN Each zone has four possible Operating Modes; these are OFF, AUTO, ONCE, CONT. Pressing the MODE button for each zone scrolls round these modes in sequence, and the display indicates which mode is currently active. ZONE 1 ZONE 2 ZONE 1 ZONE 2 • OFF mode The zone will remain OFF. • AUTO (Automatic) mode The zone will be switched ON and OFF according to the zone programme. • ONCE mode The zone will come ON at the first programmed ON time, and go OFF at the last programmed OFF time. • CONT (Continuous) mode The zone will remain ON continuously. Overriding the Operation Without Changing the Programmes In AUTO and ONCE operating modes, the OVERRIDE buttons switch the zone ON or OFF without altering the programme. When the indicator lamp is ON, pressing the OVERRIDE button switches the zone OFF until the next programmed ON time. When the indicator lamp is OFF, pressing the OVERRIDE button switches the zone ON until the next programmed OFF time. The LoT™ Display will provide you with information about the override. 10 OPERATING YOUR ST9500C The Extra Hour Function (for Zone 1 and/or Zone 2) The EXTRA HOUR buttons allow you to switch the zone ON for up to 3 extra hours without altering the programme. Pressing either button once will give one extra hour. The LoT™ Display will display the message ‘+ 1 HOUR’, to confirm the button has been pressed. When the green INDICATOR LAMP is OFF, pressing an EXTRA HOUR button switches the zone ON for just one hour. When the green INDICATOR LAMP is ON, pressing an EXTRA HOUR button extends the programmed ON period by one hour. Further presses of the EXTRA HOUR buttons will increase the extra hour period by one hour for each button press, up to a maximum of 3 hours. The LoT™ Display will continue to provide information on the extra hour status. To cancel the extra hours, just keep pressing the EXTRA HOUR button until the ‘CANCELLED’ message appears on the LoT™ Display. The Holiday Function The Holiday function allows you to switch off your system for a specified number of days (from 1-99 days). This lets you save energy and related costs when you are away from home, but resumes normal operation on the day of your return. To set the Holiday function: a. Ensure the slider is in the RUN position, then press the HOLIDAY button once. The message ‘SET HOLIDAY’ will appear briefly, followed by ‘SET DAYS AWAY’. b. Use the or buttons to set the number of days you will be away. The display will show the number of days, and this number will be flashing to indicate it can be changed. The day of the week will also keep changing to show the day you return. c. If you have made a change to the number of days, the message ‘DAYS AWAY OK ?’ will appear. Press the green button to confirm your selection. d. The message ‘SAVED’ will be displayed for a few seconds, followed by the date you return, to enable you to check you have programmed the holiday function correctly. e. During the holiday period, the LoT™ Display will show the message ‘ON HOLIDAY’ and the display will count down the number of days till you return. To cancel the Holiday function: f. To cancel the Holiday function, just press the HOLIDAY button again. The LoT™ Display will show ‘CANCELLED’ and the unit will return to normal operation. Note: while setting the Holiday function, if there is a gap of more than 1 minute between button presses, the function will cancel itself automatically and return to normal operation. 11 FINE TUNING YOUR ST9500C Changing from AM/PM Time Display to the 24 Hour Clock Your ST9500C can operate on the 12 hour AM/PM or 24 hour clock formats. To change the format, ensure the slider is in the RUN position then press and hold the and buttons together for about 2 seconds. Ignore the ‘NOT VALID’ message that will appear briefly. All the displayed times will be automatically changed to the new format. Repeating this procedure will change the clock display back to the original format.

Note: Installer Mode will exit automatically after 10 minutes if the slider is not moved. 13 FAQ AND TROUBLESHOOTING How do I set the time only, if the ST9500C clock is not correct? Your ST9500C contains a very accurate digital clock that is factory pre-set. Should you ever need to change the time, just follow this procedure: a. Move the slider to the DAY/TIME position. b. Keep pressing the green button until the message ‘SET THE TIME’ is displayed. To change the time, press the or buttons until the correct time is shown. 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’. c. Move the slider to the RUN position, to complete changing the time. What do I do when the clocks go back in October and forward in March? Your ST9500C is factory-set to adjust the clock automatically at the correct dates, so you should never need to adjust the clock forward or backwards yourself. It is possible to disable this particular feature, as described in the section ‘Changing the Installer Parameters’ (page 12). You may also check the section ‘Configuration & Service Data’ (page 18) to see how your Installer has configured your product. What should I do if I get ‘lost’ while programming the ST9500C? The LoT™ Display on ST9500C will provide you with help and tips to work through the programming. Should you ever get ‘lost’, the simplest thing to do is to move the slider to the RUN position, and then move it back to the appropriate programming position where you got lost. At this point just follow the instructions again. What happens if there is a power failure? In the event of a mains power failure, the ST9500C display will go blank, the indicator lamps will go out, and the control outputs will switch off. The real time will be constantly maintained by means of the built-in battery backup, ready to power back up as if nothing had happened when the mains power is restored. In addition, all programmes and settings are stored in a special memory (called NV memory) which requires no power to maintain information, and so will be retained indefinitely. Should the correct time and date ever be lost, for whatever reason, the message ‘SET DATE + TIME’ will be displayed whilst the slider is in the RUN position. In this case, simply follow the procedure described under ‘Step 1: Setting the Date & Time’ (page 4). It should not be necessary to make any changes to your programmes. 14 FAQ AND TROUBLESHOOTING Troubleshooting Guide This is a quick guide to help you diagnose and cope with possible problems with ST9500C.
