Choosing the Operating Mode

The CM737 can operate in three different
modes: Automatic, Manual or Off. To set the
operating mode press either of the AUTO,
MAN or OFF buttons. The screen indicates
which mode is currently active by displaying
AUTO, MAN or OFF.
• AUTO (automatic) mode sets the CM737 to
follow the built-in temperature program (de-
fault or personalised). Operating the CM737
in this mode is the best way to maintain a
high level of temperature comfort whilst
maximising your energy savings.
• MAN (manual) mode sets the CM737 to
act as a simple CM737 with a fixed setpoint
throughout the day. The setpoint can be ad-
justed from 5°C to 35°C by using the
buttons. The CM737 will continue to main-
tain this temperature until another operating
mode or temperature is selected.
• OFF mode sets the CM737 to control to a
minimum temperature setting of 5°C (de-
fault) that acts as a frost protection measure
for your home.

During Normal Operation

• Temperature Enquiry
In AUTO, MAN and OFF operating modes
the CM737 will display the current room
temperature. To review the programmed
'target' temperature (the temperature which
the CM737 is trying to maintain) press the
button. This 'target' temperature value will
be displayed flashing for 5 seconds before
returning to the current room temperature
value.
• Temperature Override
During normal operation (AUTO mode) the
programmed temperature can be adjusted
manually by pressing the
or the button. The 'target' temperature will
be displayed and flash for 5 seconds - dur-
ing this time the
used to modify the set value. Note: This
temperature override is cancelled at the
next programmed temperature change.
