VRV IV System Air Conditioner
4P329765-1 – 2012.09
Installation and operation manual
40
Change [2-9]=0, 1, 3 or 6 in function of required
operation method during heating.
For more information and advice about the impact of
these settings, see
"15.4. Energy saving and optimum
operation" on page 42
.
[2-12]=
Enable the low noise function and/or power
consumption limitation via external control adaptor
(DTA104A61/62)
If the system needs to be running under low noise
operation or under power consumption limitation
conditions when an external signal is sent to the unit,
this setting should be changed. This setting will only be
effective when the optional external control adaptor
(DTA104A61/62) is installed.
Default value=0.
To activate this function change [2-12]=1.
[2-14]=
Input additional refrigerant amount that was charged
(required for automatic leak detection operation)
In case you want to use the automatic leak detection
functionality, it is required to input the total additional
refrigerant charge amount. For details concerning the
charging procedure, see
"14.4. Method for adding
refrigerant" on page 33
. For details concerning the
calculation of additional refrigerant charge amount, see
"14.3. Calculating the additional refrigerant charge" on
page 32
. For guidance concerning the input of the
additional refrigerant charge amount and leak detection
function see
"15.3. Leak detection function" on page 42
.
Default value=0.
To activate this function change [2-14]=1~18 according
to below table:
[2-18]=
Fan high static pressure setting
In order to increase the static pressure the outdoor unit
fan is delivering, this setting should be activated. For
details about this setting, see technical specifications.
Default value=0.
To activate this function change [2-18]=1.

[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.
Further instructions regarding the different ways to
charge additional refrigerant into your system can be
found in chapter
"14.4. Method for adding refrigerant"
on page 33
.
Default value=0.
To activate this function change [2-20]=1.
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 value=0.
To activate function change [2-21]=1.
To stop the refrigerant recovery/vacuuming mode, push
BS3. If BS3 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 (3: Level 3<2: Level2<1: Level1).
The start and stop moments for this function are defined
under setting [2-26] and [2-27].
Default value=0.
To activate function change [2-22]=1, 2 or 3.
[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 (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 activate function change [2-25]=1, 2 or 3.
[2-26]=
Low noise operation start time
Change [2-26]=1, 2 or 3 in function of required timing.
Default value=2.
This setting is used in conjunction with setting [2-22].
[2-27]=
Low noise operation stop time
Default value=3.
