▪ 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.

This setting is used in
conjunction with setting [2‑8].
Heating operation
[2‑82]=3.
This setting is used in
conjunction with setting [2‑9]
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.
▪ 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.
▪ The start up condition is different from the powerful and quick
comfort setting.
