How do I change the batteries on the CM907 when they run out?
The  thermostat  constantly  monitors  the  battery  power  level,  which  typically  last  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’ on page 3), 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 and date settings to be correct.
How do I set one temperature for the whole day?
To operate as a simple thermostat with one temperature for a period of time, move the slider switch to the MAN position. Adjust the manual 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.
What is Optimum Start?
Optimum Start is a program which ensures that the optimum temperature conditions are achieved at the required times. This is an Energy Efficiency feature that adjusts the  start  time  of  your  heating  system  depending  upon  how  cold  it  is.  For  example, on cold days your heating system will be started earlier to ensure that your home is warm when you get up (at the target temperature) and on warmer days the heating system will be started later to save energy. So, if the Optimum Start Feature is used, then  the  time  /  temperature  settings  which  are  entered  into  the  thermostat  should be set to when you want to be warm by and not when you want the heating system to start.

FAQ’s & TROUBLESHOOTING
Can I use my CM907 to control my air-conditioning system?
Yes, if your system has been set up correctly you can use your thermostat to control the  cooling.  To  switch  the  thermostat  between  heating  and  cooling  modes  press the   or  buttons together for 5 seconds in any of the product operating modes (AUTO, MAN or OFF).  The  text  ‘COOLING’  will  be  displayed  for  a  moment  on  the screen to indicate the cooling operation is now active. The factory default program for cooling is specified in the table below, but this can be modified in the same way as the default heating program:
Monday to Friday
Period 1 2 3 4 5 6
Time 6:30 8:00 12:00 14:00 18:00 22:30

If something happens to my heating system how can I check that the thermostat is working?
Refer to the Troubleshooting Guide on page 17. If you still need assistance after this call your installer. The thermostat should only be opened or removed by a qualified professional  to  prevent  possible  injury  from  electric  shock  and/or  damage  to  the product.

What other accessories can I buy that work with the CM907?
1. Outside Temperature Sensor Accessory
 The  Outside  Temperature  Sensor  accessory  can  be  fitted  to  your  thermostat  to display the outside temperature. By pressing the  button twice, the thermostat displays the external temperature.
2. Remote Temperature Sensor Accessory
 The  Remote  Temperature  Sensor  accessory  can  be  fitted  to  your  thermostat  to control  the  temperature  of  another  room  where  it  is  inconvenient  to  locate  the thermostat  e.g.  commercial  premises  where  the  public  may  tamper  with  the buttons.
Note: For more information on the above accessories please contact your installer.

...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.
