Adjusting the heating curves
If the room temperature does not meet your require-
■
ments for a prolonged period of time you can alter
the heating characteristics.
■ You alter the characteristics by changing the slope
and level of the heating curve. For more information
regarding the heating curve, see page 21.
■ Please observe the modified heating characteristics
over several days (if possible, wait for a major
change in the weather) before making further adjust-
ments.
