Free cooling mode is suitable for night ventilation in the summer. When the
mode is activated and all selecte4d conditions are met, the bypass opens
completely to allow cooler air into the room.
Free cooling mode (free night cooling) is also taken into account when
the unit is in standby mode (the unit starts at a selected date and time
and checks whether the free cooling mode can be activated (Pre-free
cooling).

Menu 17 – PID parameters
Set control parameters: If the control system is unstable, the configuration can
only take place following consultation with the manufacturer.
Menu 13 – Emergency airflow
The emergency input has highest priority(deactivates all other
modes, including frost protection).
