Description
[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.
(default)
Deactivated.
Activated.
To stop the refrigerant recovery/vacuuming
mode, push BS1. If BS1 is not pushed, the
system will remain in refrigerant recovery/
vacuuming mode.
[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].
(default)

[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.

[2‑30]
Power consumption limitation level (step 1) via the external control
adaptor (DTA104A61/62).
If the system needs to be running under power consumption
limitation conditions when an external signal is sent to the unit, this
setting defines the level power consumption limitation that will be
applied for step 1. The level is according to the table.

[2‑31]
Power consumption limitation level (step 2) via the external control
adaptor (DTA104A61/62).
If the system needs to be running under power consumption
limitation conditions when an external signal is sent to the unit, this
setting defines the level power consumption limitation that will be
applied for step 2. The level is according to the table.
30%
(default)
40%
50%
[2‑32]
Forced, all time, power consumption limitation operation (no
external control adaptor is required to perform power consumption
limitation).
If the system always needs to be running under power
consumption limitation conditions, this setting activates and defines
the level power consumption limitation that will be applied
continuously. The level is according to the table.
(default)
Function not active.
Follows [2‑30] setting.
Follows [2‑31] setting.
