The above setting is used to adjust the response of the flow temperature setpoint to
varying outside temperatures.

> 20
The room temperature will respond more
slowly
to outside temperature variations.

Save sensors
At midnight, the basic unit saves the states at the sensor terminals.
If, after storage, a sensor fails, the basic unit generates an error message.
This setting is used to ensure immediate saving of the sensors. This becomes a
requirement when, for instance, a sensor is removed because it is no longer needed.
