Changing the Heating Curve

Stopping Central Heating
Your system's heating characteristics are affected by the
slope and the shift of the selected heating curve. Further
information about the heating curve can be found under
"Terminology" on page 43.
Factory setting:
H Slope: 1.4
H Heating curve shift: 0
H Standard room temperature (set value): 68º F (20º C)
H Reduced room temperature (set value): 37º F (3º C)
