The BOOST feature automatically adjusts the fan speed and heat profile according to the load size entered prior to roasting.
The adjustment is based on the default default fan speed profile is designed for a load size of 120g for the Kaffelogic Nano 7.
Sometimes profiles are developed for different default load sizes. For example, some profiles have been optimised for 100g. The problem with BOOST is that if you enter 100g with a profile like this, it will adjust down from the default 120g and this will give the wrong fan speed and heat for this profile and load.
This is where the 'reference load size' setting comes in. Setting reference load size to 100g tells BOOST to adjust from 100g. This setting needs to be done in the profile, ideally by the profile designer. However, if . This means its ‘reference load size’ is 120g. Do not change this if you are using the default fan profile. If you change this the BOOST system will apply incorrect fan speeds.
Reference load size is an expert setting.
If you are designing your own fan profile you are free to design for any load size. The 'reference load size' setting lets the BOOST system know the load size you have designed for. For example, you might design a fan profile to work optimally with 80g. Enter a reference load size of 80. This means the BOOST feature will use your fan profile unadjusted for a load of 80g, and will adjust the fan to run faster for 100g, 120g etc, or slower for 70g, 60g, etc.
When would you alter the ‘reference load size’ of a profile?
If you have a profile that you know is designed for 100g or 80g, but you obtained it before ‘reference load size’ was available as a setting, you can edit the profile yourself in Kaffelogic Studio to ensure it has the correct 'reference load size' setting.

Notes
Reference load size requires Kaffelogic Studio version 6.1.4 or higher and firmware v7.10.6 or higher.
Reference load size works best with firmware version 7.11.1 or higher (due to a small problem with fan preview and reference load size in v7.10.6).
