The Genius Hub can automatically calculate the pre-heat duration for a chosen room, so that the room will reach the set temperature at the start of the ‘heating period’, rather than just starting to heat up at that time. Your Genius Hub is adaptive, so it's always learning from the temperature recorded by each room each temperature sensor. Using the local weather data and the heating history for each room, it will constantly adjust the pre-heat duration as the weather changes. This default setting for pre-heating is disabled.

...

When pre-heating is enabled, the system will start to heat the room before the start of the heating period so the room is up to temperature at the start of the heating period. For example, if you set a heating period between 14:00 and 16:00 the system will start to heat the room at 13:00 so the zone has reached its set temperature at 14:00. When a zone is pre-heating, the set temperature for the zone will be that of the upcoming heating period, not the one currently indicated on the timer bars. To show that that the zone is pre-heating due, the pre-heating symbol will be coloured to show why the zone is heating before the heating period has started.

• 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 (bear in mind that the next heating period may be tomorrow). This can be checked on the Zone Setup page at any time. If it reads 5 or 0 minutes this means that the room is up to temperature for the current heating period.

• Manual pre-heat: This option lets you choose how much sooner the room will begin to heat than the start time of the heating period. This manually entered number will always be used, no matter the amount of heating required in the zone to reach the set temperature.
