Field Setting from Outdoor Unit
Part 5 Field Settings and Test Operation
238
[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.
