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.
