What is a programmable room thermostat ?

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

2

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
18ºC, 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 adjustment above
these setting 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

3

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.

Installation Procedure

DO’s

1. Do mount the thermostat at eye level.

2. Do read the instructions fully so that you get the best
from our product.

DON’Ts

1. Do not install near a direct heat source as this will affect
the workings of the thermostat.

2. Do not push hard on the LCD otherwise you will damage
the liquid crystal display and this is not repairable.

Installation

The thermostat is designed to be flush mount, a back
box of 35mm should have been sunk in the wall prior to
installation.

Step 1
Carefully separate the front half of the thermostat from the
back plate by placing a small flat head terminal driver in to
the slots on the bottom face of the thermostat.

5

Step 2
Carefully unplug the ribbon connector which is plugged in to
the front half of the thermostat.

Place the thermostat front half somewhere safe. Terminate
the thermostat as shown in the diagrams at the back of this
booklet.

Screw the thermostat back plate on to the back box

Step 3
Re-connect the thermostat ribbon cable and clip the two
halves together.

Comfort Levels Explained

Comfort levels allow you to set different temperatures
throughout the day. For example, you may want the home
warm in the morning when you are getting ready for work,
cooler during the day when the house is unoccupied and
then warmer in the evening when you are home relaxing.
The thermostat offers 5/2 Day Programming (4 levels for
the weekday, 4 for the weekend) and 7 day Programming (4
levels for each day). See pages 19-23 for details on how to
switch between these modes.

Tip ! If you don’t want to use all of the comfort levels, just
set the time to --.—and the thermostat will ignore this
setting.

you will be going out for a number of hours. It allows you to
hold a temperature for a desired period.

• Press HOLD

• Set the desired Hold time and temperature

• Press Done

• To cancel a Hold time, reduce the time to 00.00

14

Hot Water Override

15

Holiday

The Holiday function reduces the set temperature in your
home to the frost temperature setting. The thermostat will
maintain this temperature for the duration of the holiday and
will then automatically return to the program mode on your

and then disappear. The thermostat has then been reset to
the factory defaults.

18

THE FOLLOWING SETTINGS ARE OPTIONAL

AND IN MOST CASES NEED NOT BE ADJUSTED

Optional Features Explained

Feature 01 – Temperature Format: This function allows

you to select between °C or °F.

Feature 02 - Switching Differential: This function allows
you to increase the switching differential of the thermostat.
The default is 1°C which means the thermostat will switch
the heating on 0.5°C below the set temperature and will
turn it off 0.5°C above the set temperature. With a 2°C
differential, the heating will switch on 1.5°C below the
set temperature and will switch off 0.5°C above the set
temperature.

Feature 03 - Frost Protect: You can set whether the
thermostat will maintain the frost temperature when
the thermostat display is turned off. As a default, this is
enabled.

19

Feature 04 – Frost Protect Temperature: This is the
temperature maintained when the thermostat is in frost
mode. The range is 07-17°C. The default is 12°C and is
suitable for almost all applications.

Feature 05 – Output Delay: To prevent rapid switching, an
output delay can be entered. This can be set from 00-15
minutes. The default is 00 which means there is no delay.

Feature 06 – Communication Address: This setting
is used when you have connected your thermostat to a
network system. Each thermostat on the network must have
a unique communication address. This can be set from
01-32.

Feature 07 – Temperature Up/Down Limit: This function
allows you to limit the use of the up and down temperature
arrow keys. This limit is also applicable when the thermostat
is locked and so allows you to give others limited control
over the heating system.

Feature 08 – Sensor Selection: This thermostat has a built
in air sensor only.

20

Feature 09 – Floor Limit Sensor: This function is not used
on this model.

Feature 10 – Optimum Start: Optimum start will bring the
heating on early if needed, so the house is warm when you
wake up. This means you don’t need to allow any extra
heat up time when programming the comfort levels. The
thermostat will automatically learn the required heat up time
and will adjust itself, if required, throughout the year.

Feature 11 – Rate Of Change: This is the number of
minutes the thermostat has calculated it takes to raise your
building 1°C. The thermostat will continue to learn the heat
up time of your home and will adjust this setting to suit.

Feature 12 – 5/2 Day, 7 Day Programmable: This
function allows you to switch between 5/2 day or 7 day
programming. 5/2 day means you can program 4 comfort
levels for the weekday and 4 different levels for the
weekend. 7 day programming allows you to program 4
temperature levels for each day of the week.
