• Mild
Overshoot (during heating operation) or undershoot (during cooling
operation) is allowed compared to the requested refrigerant temper-
ature, 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 43°F (6°C) on temporary base depending on the situ-
ation.
In case of heating operation the condense temperature is allowed to
go up to 115°F (46°C) on temporary base depending on the situa-
tion.
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 com-
fort setting.
• To activate the mild comfort setting under cooling operation,
change field setting [2-51]=1.
This setting is used in conjunction with setting [2-8].
• To activate the mild comfort setting under heating operation,
change field setting [2-52]=1.
This setting is used in conjunction with setting [2-9].
• Eco
The original refrigerant temperature target, which is defined by the
operation method (see above) is kept without any correction, unless
for protection control.
• To activate the mild comfort setting under cooling operation,
change field setting [2-51]=0.
This setting is used in conjunction with setting [2-8].
• To activate the mild comfort setting under heating operation,
change field setting [2-52]=0.
This setting is used in conjunction with setting [2-9].

No matter which control is selected, variations on the behavior of the
system are still possible due to protection controls to keep the unit oper-
ating under reliable conditions. The intentional target, however, is fixed
and will be used to obtain the best balance between energy consump-
tion and comfort, depending on the application type.
