Automatic pre-heat: This option allows the Genius Hub to apply its automatically calculated pre-heat time to this zone, given the set temperature, measured temperature and weather conditions. This time is calculated in real time based on the next target temperature in the schedule (bare bear in mind that the next heating period may be tomorrow). If it reads 5 or 0 minutes this means that the room is up to temperature for the current heating period.
