Description
[2‑20]
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.
(default)
Deactivated.
Activated.
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.
[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].

[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.
