Readjusting the default settings

If the required room temperature is not obtained, readjust-
ment may be necessary.

Cold weather conditions

■

When the room temperature is too low, the “Heating
curve” value is increased in menu 2.1.2 by one increment.

■

When the room temperature is too high, the “Heating
curve” value is decreased in menu 2.1.2 by one incre-
ment.

Warm weather conditions

■

If the room temperature is low, increase the “Heating
curve offset” setting by one step clockwise.

■

If the room temperature is high, reduce the “Heating
curve offset” setting by one step anti-clockwise.
