19.3.2 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.
Powerful
Overshoot (during heating operation) or undershoot (during cooling operation) is
allowed compared to the requested refrigerant temperature, in order to achieve
the required room temperature very fast. The overshoot is allowed from the start
up moment.
▪ In case of cooling operation the evaporating temperature is allowed to go down
to 3°C on temporary base depending on the situation.
▪ In case of heating operation the condense temperature is allowed to go up to
49°C on temporary base depending on the situation.
▪ When the request from the indoor units becomes more moderate, the system
will eventually go to the steady state condition which is defined by the operation
method above.
