Enable the low noise function and/or power consumption limitation
via external control adaptor (DTA104A61/62).
If the system needs to be running under low noise operation or
under power consumption limitation conditions when an external
signal is sent to the unit, this setting should be changed. This setting
will only be effective when the optional external control adaptor
(DTA104A61/62) is installed.

Manual additional refrigerant charge.
In order to add the additional refrigerant charge amount in a manual
way (without automatic refrigerant charging functionality), following
setting should be applied. Further instructions regarding the different
ways to charge additional refrigerant into your system can be found
in chapter "6.7.2 About charging refrigerant" on

To stop the manual additional refrigerant
charge operation (when the required additional
refrigerant amount is charged), push BS3. If
this function was not aborted by pushing BS3,
the unit will stop its operation after 30 minutes.
If 30 minutes was not sufficient to add the
needed refrigerant amount, the function can be
reactivated by changing the field setting again.

Refrigerant recovery/vacuuming mode.
In order to achieve a free pathway to reclaim refrigerant out of the
system or to remove residual substances or to vacuum the system it
is necessary to apply a setting which will open required valves in the
refrigerant circuit so the reclaim of refrigerant or vacuuming process
can be done properly.
[2‑21]
0 (default) Deactivated.

To stop the refrigerant recovery/vacuuming
mode, push BS3. If BS3 is not pushed, the
system will remain in refrigerant recovery/
vacuuming mode.
