Example:
Checking the content of parameter [2‑18] (to activate or deactivate the high static
pressure setting of the outdoor unit's fan).
[Mode‑Setting]=Value in this case is defined as: Mode=2; Setting=18; Value=the
value we want to know/change.
1 Make sure the 7‑segment display indication is in the default situation (normal
operation).
2 Push BS1 for more than five seconds.
Result: Mode 2 is accessed:
3 Push BS2 18 times (or press and hold BS2 until the display reaches 18, then
release).
Result: Mode 2 setting 18 is addressed:
4 Push BS3 one time. The display shows the status of the setting (depending on
the actual field situation). In the case of [2‑18], the default value is "0", which
means the ventilated enclosure function is deactivated.

current setting situation.

on the 7‑segment display.
