Setting
[2‑32]
Forced, all time, power consumption limitation 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.
[2‑38]
Type of indoor units
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 codes might occur.
[2‑41]
Cooling comfort setting.
This setting is used in conjunction with setting [2‑8].
[2‑42]
Heating comfort setting.
This setting is used in conjunction with setting [2‑9].

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.

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.
To activate this in...
Cooling operation
Heating operation
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.
