In case of cooling operation the evaporating temperature is allowed
to go down to 43°F (6°C) on temporary base depending on the
situation.
In case of heating operation the condense temperature is allowed
to go up to 115°F (46°C) on temporary base depending on the situ-
ation.
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.
• To activate the quick comfort setting under cooling operation,
change field setting [2-81]=2.
This setting is used in conjunction with setting [2-8] and [2-47].
• To activate the quick comfort setting under heating operation,
change field setting [2-82]=2.
This setting is used in conjunction with setting [2-9].
•
Mild
Overshoot (during heating operation) or undershoot (during cooling
operation) is allowed compared to the requested refrigerant tem-
perature, 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 opera
-
tion mode above.
In case of cooling operation the evaporating temperature is allowed

In case of heating operation the condense temperature is allowed

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.
• To activate the mild comfort setting under cooling operation,
change field setting [2-81]=1.
This setting is used in conjunction with setting [2-8] and [2-47].
• To activate the mild comfort setting under heating operation,
change field setting [2-82]=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 [2-81]=0.
This setting is used in conjunction with setting [2-8] and [2-47].
• To activate the mild comfort setting under heating operation,
change field setting [2-82]=0.
This setting is used in conjunction with setting [2-9].
