Quick
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 6°C on temporary base depending on the situation.
▪
In case of heating operation the condense temperature is allowed to go up to
46°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.

Mild
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 not allowed from the
start up moment. The start up occurs under the condition which is defined by the
operation mode above.
