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 step 2.
The level is according to the
table.

[2‑32]
Forced, all time, power

operation (no external control
adaptor is required to perform
power consumption
limitation).
If the system always needs to
be running under power
consumption limitation
conditions, this setting
activates and defines the
level power consumption
limitation that will be applied
continuously. The level is
according to the table.

After changing this setting,
you have to power OFF the
system, wait for 20 s, and
then power ON again. If not,
the setting will not be
processed and malfunction

7.3 Energy saving and optimum
operation
This heat pump system is equipped with advanced energy saving
functionality. Depending on the priority, emphasises can be put on
energy saving or comfort level. Several parameters can be selected,
resulting in the optimal balance between energy consumption and
comfort for the particular application.
Several patterns are available and explained below. Modify the
parameters to the needs of your building and to realize the best
balance between energy consumption and comfort.
No matter which control is selected, variations on the behaviour of
the system are still possible due to protection controls to keep the
unit operating under reliable conditions. The intentional target,
however, is fixed and will be used to obtain the best balance
between energy consumption and comfort, depending on the
application type.
7.3.1 Available main operation methods
Basic
The refrigerant temperature is fixed independent from the situation. It
corresponds to the standard operation which is known and can be
expected from/under previous VRV systems.

Cooling operation [2‑8]=2
Heating operation [2‑9]=2
Automatic
The refrigerant temperature is set depending on the outdoor ambient
conditions. As such adjusting the refrigerant temperature to match
the required load (which is also related to the outdoor ambient
conditions).
E.g., when your system is operating in cooling, you do not need as
much cooling under low outdoor ambient temperatures (e.g., 25°C)
as under high outdoor ambient temperatures (e.g., 35°C). Using this
idea, the system automatically starts increasing its refrigerant
temperature, automatically reducing the delivered capacity and
increasing the system's efficiency.
E.g., when your system is operating in heating, you do not need as
much heating under high outdoor ambient temperatures (e.g., 15°C)
as under low outdoor ambient temperatures (e.g., –5°C). Using this
idea, the system automatically starts decreasing its refrigerant
temperature, automatically reducing the delivered capacity and
increasing the system's efficiency.

Hi-sensible/economic (cooling/heating)
The refrigerant temperature is set higher/lower (cooling/heating)
compared to basic operation. The focus under high sensible mode is
comfort feeling for the customer.
The selection method of indoor units is important and has to be
considered as the available capacity is not the same as under basic
operation.
For details concerning to Hi-sensible applications, please contact
your dealer.

Cooling operation [2‑8] to the appropriate value,
matching the requirements of the
pre-designed system containing
a high sensible solution.
