FAQ’s

• Automatic Summer/Winter Time Change

The CM721 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.

‘Using the Features’ OPERATING THE CM721

BDR91 Relay Box Controls Layout

The relay box will normally be found mounted

close to the boiler.

What does it mean when the BDR91

relay box green LED is ON?
