To install the Batteries:

1. Lift up the front cover of the thermostat to reveal the battery cover and product controls.
2. Remove the battery cover by pressing down and sliding out.
3. Insert the 2 x AA LR6 Alkaline Batteries supplied with the thermostat, ensuring the correct orientation (see Controls Layout).
4. After a short pause the thermostat will display information on the screen and is now ready for use.
5. Replace the battery cover by sliding it firmly back into the front of the thermostat.

PLEASE RESPECT YOUR ENVIRONMENT! Take care to dispose of used batteries carefully.

STEP 2: Setting the Day and Time

To set the Day and Time:

1. Press the DAY button once and the ‘day indicator’ will begin to flash.
2. Press the DAY button until the correct day is reached (Day 1 = Monday). Press the green button to confirm.
3. Press either of the or buttons once to enter time setting mode. The LCD screen flashes the time digits (when the unit is powered for the first time the display shows 12:00).
4. 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 customize the settings please see the next section ‘Programming the CM707.

The Built-in Heating Program

The built-in heating program has 6 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 6 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:

1. Press either of the PROGRAM or 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.
   
2. To adjust the period start time use the  or 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.
3. 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’.
4. The temperature setting for period 1 on Monday (Day 1) will now be flashing. To adjust this press the or buttons and confirm the setting again by pressing the green button.
5. The next time and temperature period will now be active. Adjust this by repeating steps b – d above until all 6 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:
6. i) Press the COPY DAY button to copy Monday’s program into Tuesday. The display will go blank apart from the ‘non flashing’ day indicator, which indicates the day copied and the ‘flashing’ target day to copy the program to. 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
   ii) 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 e. 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 6 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 6 can be removed from (or returned to) the heating program profile.

To disable or enable time periods:

1. To disable unwanted periods go to the desired period ( 2 to 6 ) using the PROGRAM or buttons to navigate, 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.
2. 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.

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 personalized). Operating the thermostat in this mode is the best way to maintain a high level of temperature comfort whilst maximizing your energy savings.
• MAN (manual) mode sets the thermostat to act as a simple thermostat with a fixed set point throughout the day. The set point can be adjusted from 5°C to 35°C by using the or buttons. The thermostat will continue to maintain this temperature until another operating mode or temperature is selected.
• OFF mode sets the thermostat to control to 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 the or buttons or the button. The ‘target’ temperature will be displayed and flash for 5 seconds – during this time the or buttons can be used to modify the set value. Note: This temperature override is cancelled 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  or time buttons to set the holiday time (1 – 99 days) and press the green button to confirm.
• Press the or buttons to set the holiday temperature (5°C – 35°C) and press the green button 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. The thermostat 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 button a second time.

Adjusting the Time

To adjust only the time during normal operation use the or buttons to adjust the time and press the green button again to confirm any changes.

FAQ’s

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 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), replacing the used batteries with new ones 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 or 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.
