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.
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 installer.
9.2 Available comfort settings
For each of above modes a comfort level can be selected. The comfort level is
related to the timing and the effort (energy consumption) which is put in achieving
a certain room temperature by temporarily changing the refrigerant temperature
to different values in order to achieve requested conditions more quickly.

INFORMATION
Combinations of Automatic mode together with Hydrobox applications should be
considered. The effect of the energy saving function can be very small when low/high
(cooling/heating) leaving water temperatures are requested.
