PROGRAMMING THE CM727
Using the Special Features
‘Using the Features’
•
SERVICE indicator (optional)
Note: This option only works if activated by your installer.
The 'SERVICE' indicator is displayed at set
intervals as a reminder that your heating system
requires a routine check. Please call your installer
to arrange a maintenance visit.
The ‘SERVICE’ indicator will remain on the display
of the CM727 until it is either reset or disabled by
your installer. The CM727 and heating system will
continue to operate as normal.

Automatic Summer/Winter Time Change
The CM727 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
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.
