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.

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.

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.
Care should be taken about selection procedures and system
setups, especially when using Hydrobox units. The requested
leaving water temperature from the Hydrobox has priority over this
energy saving control, as it is related to the required water
temperature.
