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.

This section shows you how to setup and run the thermostat in 3 simple steps:
STEP1:InstallingtheBatteries
Note: Please follow the instructions in this section only if the thermostat screen
is blank (no symbols or digits are displayed). If the room temperature is already
displayed move on to Step 2: Setting the Date and Time.
To install the Batteries:
a. Lift up the front cover of the thermostat to reveal the battery cover and product
controls.
b. Remove the battery cover by pressing down and sliding out.
c. Insert the 2 x AA LR6 Alkaline Batteries supplied with the thermostat, ensuring the
correct orientation (see ‘Controls Layout’ above).

d. After a short pause the thermostat will display information on the screen and is now
ready for use.
e. Replace the battery cover by sliding it firmly back into the front of the thermostat.
STEP2:SettingtheDateandTime
To set the Date and Time:
a. Press the DATE/DAY button to begin setting the date. When you set the date
for the first time after the batteries are inserted, the
display will show:
Press the or buttons to set the current day of
the month (e.g. d 01 = 1st day of the month) then press
the green button to confirm.
b. Press the or buttons to set the current month of
the year (e.g. m 01 = January) then press the green
button to confirm.
c. Press the or buttons to set the current year
(e.g. yr 13 = 2013) then press the green button to
confirm.
The date is now stored and the Day Indicator will be
displayed under the current day of the week (e.g. 1 =
Monday, 2 = Tuesday, etc.)
d. Use the or buttons to set the correct time then
press the green button to confirm. Each press of
the buttons will change the time by one minute and
holding them down will change the time slowly at first
and get progressively quicker.
Note: If this mode is entered accidentally then press the AUTO, MAN or OFF
buttons to exit.
STEP3:RunningtheBuilt-inHeatingProgram
The thermostat is now ready for operation. Press the AUTO buttonandthebuilt-in
heating program will start running. Note: The built-in heating program has been
designed to provide normal comfort requirements, but if you want to customise the
settings please see the next section ‘Programming the CM707’.

OPERATING THE CM707
SpecialFeatures
• Display Backlight
The CM707 has a backlit display that will illuminate when a button is pressed for
easier viewing of the display in low light conditions.
• SERVICE indicator (optional)
Note: This option only works if activated by your installer.
The 'SERVICE' indicator is displayed at set
intervals as a reminder that your heating
system requires a routine check. Please
call your installer to arrange a maintenance
visit.
The ‘SERVICE’ indicator will remain on the
display of the CM707 until it is either reset
or disabled by your installer. The CM707
and heating system will continue to operate
as normal.

10
• Automatic Summer/Winter Time Change
The CM707 has a built-in Automatic Summer/Winter Time Change feature that
will automatically adjust the clock forward or backward by one hour for ‘Daylight
Saving Time’. This is carried out on the last Sunday of March and October each
year.
• Optimum Start (tickifenabled )
Optimum Start measures how quickly your system normally takes to heat up, and
then calculates how far in advance it needs to switch the boiler on to reach the
comfort temperature at the programmed time.
This setting ensures the desired temperatures are reached nearer the actual
programmed times, removing the need to guess how long the heating will take to
warm up.
• Delayed Start (tickifenabled )
 If you program your heating to come on early to allow it to heat up, Delayed
Start will save energy by delaying the start of the boiler a little depending on
the difference between the programmed temperature and the actual room
temperature. When the two temperatures are close to one another the delay will
be longer than when the they are further apart, and in both cases will achieve the
same set temperature within a similar time frame.
• Optimum Stop (tickifenabled )
Optimum Stop will save energy by switching the boiler off a little bit earlier than
the programmed time. If the house is up to temperature, you should not notice the
effect on the temperature, but you should see a difference in your energy bill.
When the Optimum Start or Optimum Stop function
is enabled the “OPT” symbol will appear on the
display.
