This button regulates the heating characte-
ristics of the heating circuit in relation to out-
door temperature.
The adjustment is dependent of the plant installation and
shows the relation between outdoor temperature and
heat generator (boiler) temperature.
The slope sets the change of the supply temperature, if the
outdoor temperature changes for 1 K.
