Pre-heating function

The function is active only if the heating automatic mode was selected. When set to Automatic, the function anticipates the heating system start time (not before 00:00h on the same day) so that the room temperature set by the user is reached at the start of the programmed band. The Chronothermostat calculates a first hypothetical Pre-activation time: if the programmed room temperature is reached sooner than the calculated time, the Pre-heating time is decreased and vice versa. In this way, a self-learning process is created to determine the shortest necessary pre-heating time. The Chronothermostat also offers the possibility of setting a fixed Pre-heating slope: in this case, the room temperature will be increased by 3°C an hour.

Therefore the heating automatic program must be programmed according to the time heating is required, and not that of starting the heating system.
