Setting
[2‑21]
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.
[2‑22]
Automatic low noise setting and level
during night time.
By changing this setting, you activate the
automatic low noise operation function of
the unit and define the level of operation.
Depending on the chosen level, the noise
level will be lowered. The start and stop
moments for this function are defined
under setting [2‑26] and [2‑27].
[2‑25]
Low noise operation level via the external
control adaptor.
If the system needs to be running under
low noise operation conditions when an
external signal is sent to the unit, this
setting defines the level of low noise that
will be applied.
This setting will only be effective when the
optional external control adaptor
(DTA104A61/62) is installed and the setting
[2‑12] was activated.
[2‑26]
Low noise operation start time.
This setting is used in conjunction with
setting [2‑22].
[2‑27]
Low noise operation stop time.

setting [2‑22].
