When Automatic is selected, the changing of the operation mode is
based on the Operation mode schedule [4.2]: the end user indicates
on a monthly base which operation is allowed.
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating or space cooling is prohibited.
