Setting
(=

Value
Description
[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.
(= binary 1)
(default)
Deactivated.
(= binary 2)
Activated.
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.
(= binary 1)
(default)
Deactivated.
(= binary 2)
Activated.
To stop the refrigerant
recovery/vacuuming
mode, push BS1. If it 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. The
start and stop moments for
this function are defined
under setting [2‑26] and
[2‑27].

Description
[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.
This setting will only be
effective when the optional
external control adaptor
(DTA104A61/62) is installed
and the setting [2‑12] was
activated.

[2‑30]
Power consumption limitation
level (step 1) via the external
control adaptor
(DTA104A61/62).
If the system needs to be
running under power
consumption limitation
conditions when an external
signal is sent to the unit, this
setting defines the level
power consumption limitation
that will be applied for step 1.
The level is according to the
table.
