5. Operating modes
Slope «H» of the heating curve can be used to adjust the setpoint in response to the
outside temperature, as shown in the diagram. The common origin of the heating curves
is set at (20 °C / 20 °C). The effective range of the weather-adjusted setpoint is
restricted by the setpoint limits «
SPH»
and
«SPL»
.

«HYS1»
is the switch-on point for the burner, and «
HYS3»
is the switch-off point. As
already described, they act with the set shift relative to the weather-controlled setpoint.
