[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 in the indoor unit.
[2‑15]
Fan static pressure setting (in heat exchanger unit).
You can set the external static pressure of the heat
exchanger unit according to the ducting requirements.
[2‑16]
Test run heat exchanger unit.
When activated, the heat exchanger fans start running.
This allows you to check the ducting with a running
heat exchanger 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.
[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.
[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].

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.

To stop the refrigerant recovery/vacuuming
mode, push BS1 (in case of 5 HP) or BS3 (in
case of 8 HP). If it is not pushed, the system
will remain in refrigerant recovery/vacuuming
mode.
