PROGRAMMING THE CMR707
The Built-in Heating Program
The built-in heating program has 4 temperature level changes per day that can be set between 3.00am and 2.50am the following day – allowing you to maintain the evening temperature after midnight. Each temperature level can be set between 5°C and 35°C, and adjusted in 0.5°C increments. The factory default program for heating is as follows.
Monday to Friday (Day 1 to 5)
Saturday & Sunday (Day 6 & 7)
Reviewing the Heating Program
To review or edit the heating program use the PROGRAM or buttons to navigate between the 4 individual programming periods for that day. Use the DAY button to step through each day of the week, so the complete 7 day heating program can be reviewed or edited.
Modifying the Heating Program
To change the heating program:
- Press either of the PROGRAM buttons to enter the programming mode.
The time/temperature settings for period 1 on Monday (Day 1) will be flashing as shown. The active period is highlighted by a flashing square around the numbers at the bottom of the screen and the selected day is shown with the day indicator.
- To adjust the period start time use the buttons, the ‘OK?’ indicator will be displayed to confirm the change. Holding the button down will change the time quickly.
Note: If you are pressing the or buttons and the display flashes the next period, it means the next period will be pushed forward.
- Once the required time is reached press the green button to confirm.
Note: If the original time setting did not require adjustment press the green button to move to step ‘d’.
- The temperature setting for period 1 on Monday (Day 1) will now be flashing. To adjust this press the buttons and confirm the setting again by pressing the green button.
- The next time and temperature period will now be active. Adjust this by repeating steps b – d above until all 4 periods are set for Monday or press the AUTO button to run the program as set, at any time.
You now have a choice of how to set the program for the next day:
- Press the COPY DAY button to copy Monday’s program into Tuesday. The display will go blank apart from the ‘nonflashing day indicator, which indicates the day copied and the ‘flashing’ target day to copy the program. To accept this day press the green button. To select a different target day press the DAY button until the ‘flashing’ day indicator is under the required day, then accept it by pressing the green button.
Note: Once the target day is confirmed it becomes the day that is copied if the COPY DAY button is pressed again. OR
- Press the DAY button to move the day indicator to Tuesday (Day 2). The program for that day can then be adjusted by following steps b to Programs for the remaining days can be set in the same way, using the DAY button to move to the next day. To exit the programming mode select the desired operating mode by pressing the AUTO, MAN or OFF buttons. Note: To run the adjusted program select the AUTO mode.
Disabling / Enabling Time Periods
The thermostat has 4 periods each day that can be programmed, but you may not need all of these switch points for your heating requirements. Therefore, any period from 2 to 4 can be removed from (or returned to) the heating program profile.
To disable or enable time periods:
- To disable unwanted periods go to the desired period ( 2 to 4 ) using the PROGRAM buttons to navigate, and ensure the correct period is highlighted with the flashing square symbol. Press and hold the button for at least 2 seconds and the display will indicate the period has been removed from the program.
- To enable periods again follow the same procedure as above, navigating to the already disabled period. To enable this period again press and hold the button for at least 2 seconds.
OPERATING THE CMR707
Choosing the Operating Mode
The thermostat can operate in three different modes: Automatic, Manual or Off. To set the operating mode press either of the AUTO, MAN or OFF buttons. The screen indicates which mode is currently active by displaying AUTO, MAN or OFF.
- AUTO (automatic) mode sets the thermostat to follow the built-in temperature program (default or personalised). Operating the thermostat in this mode is the best way to maintain a high level of temperature comfort whilst maximising your energy savings.
- MAN (manual) mode sets the thermostat to act as a simple thermostat with a fixed setpoint throughout the day. The setpoint can be adjusted from 5°C to 35°C by using the buttons. The thermostat will continueto maintain this temperature until another operating mode or temperature is selected.
- OFF mode sets the thermostat to controlto a minimum temperature setting of 5°C (default) that acts as a frost protection measure for your home.
During Normal Operation
- Temperature Enquiry
In AUTO, MAN and OFF operating modes the thermostat will display the current room temperature. To review the programmed ‘target’ temperature (the temperature which the thermostat is trying to maintain) press the button. This ‘target’ temperature value will be displayed flashing for 5 seconds before returning to the current room temperature value.
- Temperature Override
During normal operation (AUTO mode) the programmed temperature can be adjusted manually by pressing thebuttons the button. The ‘target’ temperature will be displayed and flash for 5 seconds – during this time thebuttons canbe used to modify the set value.
- Note: This temperature override is canceled at the next programmed temperature change. Using the Special Functions
- HOLIDAY Function
The holiday function allows you to set a constant temperature (default = 10°C) 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:
- Ensure the thermostat is running in AUTO or MAN operating modes.
- Press the holiday button to display the holiday days counter and temperature setting, along with the holiday indicator .
- Press the time buttons to set the holiday time (1 – 99 days) and press the green button to confirm.
- Press the buttons to set the holiday temperature (5°C – 35°C) and press the greenbutton to confirm.
The thermostat will now control to the new temperature for the set number of days that your home is vacant. At midnight the holiday counter will be reduced by one until the selected number of days have passed. Thethermostat will then return to normal operation as set by the MAN or AUTO mode. To cancel the HOLIDAY function or to exit the function at any time press the buttona second time.

How do I change the batteries on the thermostat when they run out?
The thermostat constantly monitors the battery power level, which typically lasts for about 2 years before needing to be replaced. When the power is running low a flashing symbol will be displayed on the screen. To change the batteries follow the steps in the above section (‘STEP 1: Installing the Batteries’ on page 3), replacing the used batteries with new in Step c.
Note: While changing the batteries your program settings will be stored but you may need to adjust the time settings to be correct.
How do I set one temperature for the whole day?
To operate as a simple thermostat with one temperature throughout the day, select the manual operating mode by pressing the MAN button. Adjust the temperature by pressing the buttons – this can be set anywhere from 5°C to 35°C in 0.5°C steps. The thermostat will continue to maintain this temperature until another operating mode is selected or the temperature is adjusted.
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 italone 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.
