[2-20]: Additional refrigerant charge
In order to add the additional refrigerant charge amount following setting should be applied.
Default value: 0
To activate this function, change [2-20] to 1.
To stop the additional refrigerant charge operation (when the required additional refrigerant amount is
charged), press the
RETURN (BS3)
button. If this function was not aborted by pressing the
RETURN
(BS3)
button, 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 recovering 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 recovering of refrigerant or vacuuming process can be done properly.
Default value: 0
To activate this function, change [2-21] to 1.
To stop the refrigerant recovery/vacuuming mode, press the
RETURN (BS3)
button. If the
RETURN
(BS3)
button 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 can 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
Change [2-22] to 1, 2 or 3 in function of required level.
[2-25]: Night-time low noise operation level via the external control adaptor
If the system needs to run under night-time low noise operation conditions when an external 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
Change [2-25] to 1, 2 or 3 in function of required level.
[2-26]: Night-time low noise operation start time
Change [2-26] to 1, 2 or 3 in function of required timing.
