Field Setting from Outdoor Unit
[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 value: 0
To activate this function: 1
To stop the manual additional refrigerant charge operation (when the required additional refrigerant
amount is charged), press BS3. If this function was not aborted by pressing 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 value: 0
To activate this function: 1
To stop the refrigerant recovery/vacuuming mode, press BS3. If BS3 is not pressed, the system will
remain in refrigerant recovery/vacuuming mode.
[2-22]: Automatic night-time low noise setting and level during night time
By changing this setting, you activate the automatic night-time low noise operation function of the unit
and define the level of operation. Depending on the chosen level, the noise level will be lowered (3:
Level 3 < 2: Level 2 < 1: Level 1).
The start and stop moments for this function are defined under setting [2-26] and [2-27].
Default value: 0
To activate this function: 1, 2, or 3
[2-25]: Night-time low noise operation level via the external control adaptor

signal is sent to the unit, this setting defines the level of night-time low noise that will be applied (3: Level
3 < 2: Level 2 < 1: Level 1).
This setting will only be effective when the optional external control adaptor (DTA104A61/62) is installed
and the setting [2-12] was activated.
Default value: 2
To change the level: 1 or 3
[2-26]: Night-time low noise operation start time
