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.
