[2-0]= Cool/Heat selection setting
Cool/Heat selection setting is used in case the optional
Cool/Heat selector (KRC19-26A) is used. Depending on the
outdoor unit setup (single outdoor unit setup or multi outdoor
unit setup), the correct setting should be chosen. More
details on how to use the Cool/Heat selector option can be
found in the manual of the Cool/Heat selector.
Default value=0.
• 0=Each individual outdoor unit can select Cool/Heat opera-
tion (by Cool/Heat selector if installed), or by defining mas
-
ter indoor user interface (see setting [2-83] on page 39).
• 1=Master unit decides Cool/Heat operation when outdoor
units are connected in multiple system combination
• 2=Sub unit for Cool/Heat operation when outdoor units
are connected in multiple system combination
Change [2-0]=0, 1 or 2 in function of required functionality.

[2-11]= Eco level setting for Eco mode via External control adaptor
(Optional).

Eco mode can be activated by short circuit the terminal on
External control adaptor (Optional) according to [2-11] set-
ting. ([2-23] should be “0”)
This unit can operate with “T
e
or T
c
fix control” and “Eco
mode”. Eco mode means “VRT” control.
If the terminal on external control adapter is not connected
by short circuit with [2-11]≠0, the system operates according
to [2-8] or [2-9] setting.
[2-12]= Enable the low noise function and/or power consumption
limitation via external control adaptor (DTA104A62)
If the system needs to run 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 (DTA104A62) is installed.
Default value=0.
To activate this function change [2-12]=1.
[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]= Additional refrigerant charge
In order to activate the additional refrigerant charge amount,
the following setting should be applied.
Default value=0.
To activate additional refrigerant charge [2-20]=1.
Further instructions can be found in chapter 14.3. Method for
adding refrigerant on page 31.
To stop the 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 func
-
tion 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
