Tc target temperature during heating operation
Default value=3
Change [2-9]=1, 3 or 6 in function of required operation
method during heating.
For more information and advice about the impact of
these settings, see
"17.4. Energy saving and optimum
[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.

Interlock (open) feedback on user interface
This setting is used to define whether you want to
receive feedback of the interlock or not. Indication is by
displaying a malfunction code on the user interface. On
top of that, the delay time by when a malfunction code is
displayed on the user interface is selectable.
Default value=0 (no feedback, no malfunction code on
the user interface).
Change [2-26]=0, 1, 2, 3, 4, 5, 6 or 7 in function of the
required delay. In case a delay time is selected, the
malfunction will be indicated on the user interface.
[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
step1. The level is according to the table.
Default value=2.
Change [2-30]=1, 2, or 4 in function of required
limitation.
[2-31]=
Power consumption limitation level (step 2) 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
step2. The level is according to the table.

INFORMATION
Even though no feedback is set ([2-26]=0),
when the interlock is open, the unit will go to
forced thermo OFF conditions. See
