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 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 programme, 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, wall or table lamps may prevent the thermostat from working properly.

User Instructions
An introduction to your
programmable room thermostat
Your programmable room thermostat allows you to programme
different temperatures at different time periods. You can programme
one set of times and temperatures for week days 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 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 programme 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 programmes

Your TP5000 Si comes ready programmed with a set of operating times
and temperatures which suit most people. Please remember that some
of the options available will depend on how the installer has set up the
unit.

Customising 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 personalised after the thermostat has been
programmed, see pages 22 - 24.

Setting the correct date and time
Your TP5000 Si incorporates a real time clock with 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 does 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
time or date for any other reason refer to the following instructions.

activated switch or window contacts to step the unit into or out of
thermostat mode.
The required temperature to be maintained when the building is
unoccupied, or when windows are open, must first be set up in User
Advanced Programming, step 10, (page 27).
To locally override this feature press both Λ and V together.

Delay start feature
Your thermostat includes an optional delay start feature to hold off
the heating for a time on mild days when the room temperature at the
start of an event is close to the programmed value. If you have enabled
this function it can be overridden by pressing either Λ or V buttons.
To enable this feature, please refer to User Advanced Programming,
step 11, (page 27).
When this function is active, the set temperature will flash on the
display and an hourglass symbol will be displayed.

Your thermostat includes an optional optimum start control. This feature
allows you to set the time at which you require a room temperature by.
The thermostat then calculates how soon before the event time the
system must be turned up to ensure that the room is at the temperature
by the required time. A full description of this and how to enable it and
set it up is given in User Advanced Programming, steps 12 & 13, (page
28). When this function is active, the set temperature will flash on the
display

different ways. Press + until Option 11 is displayed,
use Λ and V to select required setting.
Setting 0 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 0 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.

you are able to set on the thermostat.

Temperature override limitation

User Instructions

Overview of installer selectable features which GB
may affect the operation of your thermostat

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
unauthorised changes to programme values and limits 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 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.

GB 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 cancelled the alarm will recommence the Service Interval Date
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 cancelled 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 micro-computer) if display
freezes for any reason. This does not reset any programme, clock or
date. It is recommended that this is done at time of installation.
User full reset: Press RESET whilst holding down 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
are not reset.
