What is a programmable room thermostat?
an explanation for householders
A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set ‘On’ and ‘Off’ time periods to suit your own lifestyle. A room thermostat 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. So, a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs.
Turning a programmable 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 the boiler and radiators. Neither does the setting affect how quickly the room cools down. Turning a programmable room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy. The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set low temperatures first, say 18°C, and then turn them up by one degree each day until you are comfortable with the temperatures. You won’t have to adjust the thermostat further. Any adjustments above these settings will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will usually be only one programmable 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.
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 program, for example, ‘Override; ‘Advance’ or’Boost These are explained in the manufacturer’s instructions. Programmable 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, and wall or table lamps may prevent the thermostat from working properly.
An introduction to your programmable room thermostat
Your programmable room thermostat allows you to program different temperatures at different time periods. You can program one set of times and temperatures for weekdays with a different set of temperatures for weekend days, this is referred to as 5/2 day operation. The thermostat can also be set up by your installer to provide one set of times and temperatures that are repeated each day of the week. This is referred to as a 24-hour operation. The thermostat can also be set by you to provide two different programming blocks which can then be assigned to any day of the week, this is referred to as A/B program operation. All thermostats can be set by your installer to provide up 2, 4 or 6 time and temperature settings each day. All thermostats feature useful overrides, including a programmable frost setting. Your thermostat has some advanced features which the installer will set up if they are required. There are also a number of advanced features which can be set up by you. These advanced settings alter the way that your thermostat operates, some also affect the programming functions and the user overrides. Please read the User Advanced Programming instructions before programming the unit (see page 25).
Preset programs
Your TP5000 Si comes ready and programmed with a set of operating times and temperatures that suit most people. Please remember that some of the options available will depend on how the installer has set up the unit.

Before you start
Open the flap on the front of the programmer and press the RESET button with a non-metallic object until the display goes blank. This will ensure that the micro-computer in the product is operating correctly.
Customizing the display
For the sake of clarity, the instructions assume that the display setting uses a 24-hour clock, °C and that days of the week are shown as text. All of these settings can be personalized after the thermostat has been programmed, see pages 22 – 24.
Setting the correct date and time
YourTP5000 Si incorporates a real-time clock with a calendar function that automatically changes time in both Spring and Autumn. The time and date is set in the factory for the UK time zone and do not normally require adjustment. If you live in another time zone refer to ”Time zone offset” on page 26. However, should it be found necessary to adjust the time or date for any other reason refer to the following instructions.
Setting the date
Press and hold I\ and PROG for 3 seconds, to display the date in dd/mm/yy format.
- The YEAR number will flash, use I\ or V to correct the year.
- Use – or + to move to MONTH, then use I\ or V to correct month.
- Use – or+ to move to DATE in a month, then use I\ or V to correct the day in the month.
If you attempt to select an invalid date the unit software will reject it and apply the nearest valid date. It is recommended that the date is set in the order, yy/mm/dd.
Setting the correct time
After setting the date press PROG to display the time. The time display will flash on and off. Use the + and – buttons to set the correct time (press and hold to change in 10 min. increments).

Your thermostat can start up the syste in three ,,different ways. Press + until Option 11 is displayed, use I\ and V to select the required setting.  |
| Setting O Normal: Heating is turned up or down at the programmed
times. |
| Setting 1 Optimum start control (OSC) (or Comfort Setting): This allows you to programme the time at which you would like to be up to the required temperature. The thermostat then calculates how soon before the required time the heating is turned up. This will vary with weather conditions ranging from a maximum of 120 minutes to O minutes before the programmed event time. This setting must be used together with option 12 to match the optimiser setting to
the building in which it is installed. |
| Setting 2 Delay start (or Economy Setting): This is an alternative to OSC. Set the event times in the normal way taking into account the time that the building takes to heat on an average day. The thermostat monitors switch on time, actual temperature and wanted temperature and delays the start of the heating if the actual temperature is close to the programmed temperature. |
Option 12 – Optimum start control pre-heat setting (Option 11 set to 1) |
|
| Press + until Option 12 is displayed, use I\ and The optimum start control must be adjusted to match the building energy characteristics. Use the I\ and V keys to selected the required pre-heat period. The table below suggests typical settings.
If the building fails to reach temperature on time, increase the setting by 15 minute steps each day until the correct setting is found.If the building reaches temperature ahead of time, decrease the setting by 15-minute steps each day until the rrect setting is found. |

Overview of installer selectable features which
may affect the operation of your thermostat
Temperature range limitation
This allows the installer to program both upper and lower temperature limits. It may limit the upper and lower temperature that you are able to set on the thermostat.
Temperature override limitation
This allows the installer to limit the number of degrees that you can override the programmed temperature by, it also allows the installer to set rules regarding how long a temperature override will remain in place.
Keyboard lock
This allows the installer to limit or lock the keyboard to prevent unauthorized changes to program values and limit overrides.
What happens to the unit when batteries fail
If batteries are not changed within 15 days of a low battery warning, the unit shuts down. In normal circumstances, the thermostat turns off the valve or the boiler it is controlling. In extreme climates turning off the heating is likely to result in the building freezing up. To prevent this, the installer can set up the unit to turn the heating ON rather than turn OFF on battery failure. This will consume more fuel but will prevent damage from occurring to the building. If appropriate please check that the installer has set this function correctly. Please note: If you replace the batteries and the LCD does not come on immediately please check battery orientation. Do not leave batteries in the product if the display is not active. If, after changing the batteries, the screen remains blank it is necessary to carry out a partial reset. See page 30 for details.
Service Interval Timer
- If the property is owned by a landlord he may, for gas safety reasons, have instructed the installer to set the service interval timer.
- If set, 28 days prior to the service due date, a visual and audible warning will start each day at noon. The audible warning will last for 10 seconds and will be repeated every hour until a button is pressed to cancel it. If canceled the alarm will recommence the following day at noon.
- If the boiler is not serviced before the due date, a visual and audible warning will start each day at noon. The audible warning will last for 1 minute and will be repeated every hour until a button is pressed to cancel it. If canceled the alarm will recommence the following day at noon.
- In addition, all overrides and programming buttons will be disabled and the heating may operate for a limited amount of time each hour.
- The installer may cancel or reset the service interval timer as part of the boiler service.
- This is a gas safety feature that can only be accessed by an installer.
Resetting the unit
Partial reset: Press RESET (used to restart the micro-computer) if the display freezes for any reason. This does not reset any program, clock or date. It is recommended that this is done at time of installation. User full reset: Press RESET whilst holding down the PROG button. This resets event times and any User Advanced Programme setting, but does not reset time or date. Installer full reset: This is only available to the installer. In addition to the above all of the Installer Advanced Programming settings are returned to factory settings, however, time, date and service due date a re not reset.
