For end-users, the preferred method of modifying the heating system comfort level is by using the comfort level function
rather than modifying the heat curve. Here, it is possible to raise or lower the water input temperature within a range of
9°C (-3 to +6) by accessing the comfort level.
For more information please see the A-Class User Manual.
