Weather dependent regulation
When connecting an outdoor sensor, the leaving water temperature is automatically
regulated dependent on the outdoor temperature, in accordance with the set fuel line.
The maximum leaving water temperature (T max) is set via the display. If so desired,
the fuel line can be changed by using the service code (see par.7.3).
