Installation and operation manual

Mode 1 setting (H1P is OFF)
17.3. Mode 2
Mode 2 is used to change the field settings of the system. Consulting
the current field setting value and changing the current field setting
value is possible.
In general, normal operation can be resumed without special
intervention after changing field settings.
Some field settings are used for special operation (e.g., one time
operation for performing specific checks, recovery/vacuuming
setting, adding refrigerant setting, etc.). In such a case, it is required
to abort the special operation before normal operation can restart. It
will be indicated in below explanations.
[1-0]=
Cool/Heat selection setting (only for heat pump system)
Cool/Heat selection setting is used in case the optional
Cool/Heat selector (KRC19-26A and BRP2A81) 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=16.
16=Each individual outdoor unit can select Cool/
Heat operation (by Cool/Heat selector if installed),
or by defining master indoor user interface.
8=Master unit decides Cool/Heat operation when
outdoor units are connected in a multi outdoor unit
system combination
(a)
4=Slave unit for Cool/Heat operation when outdoor
units are connected in a multi outdoor unit system
combination
(a)
Change [1-0]=16, 8 or 4 in function of required
functionality.
When you change setting [1-0], the default status will
change depending on the selected setting:
(a) It is necessary to use the optional external control adaptor for outdoor unit
(DTA104A61/62). See the instruction delivered with the adaptor for further details.
[2-8]=
Te target temperature during cooling operation
Default value=5
Change [2-8]=2~7 in function of required operation
method during cooling.
For more information and advice about the impact of
these settings, see
"17.4. Energy saving and optimum
operation" on page 37

[2-12]=
Enable the power consumption limitation via 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 should be changed.
This setting will only be effective when the optional
external control adaptor (DTA104A61/62) is installed.
Default value=1 (OFF).
To activate this function change [2-12]=2 (ON).
[2-20]=
Manual additional refrigerant charge
Further instructions regarding the different ways to
charge additional refrigerant into your system can be
found in
"16. Charging refrigerant" on page 31
.
Default value=1 (OFF).
To activate this function change [2-20]=2 (ON).
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=1 (OFF).
To activate function change [2-21]=2 (ON).
To stop the refrigerant recovery/vacuuming mode, push
BS3. If BS3 is not pushed, the system will remain in
refrigerant recovery/vacuuming mode.
