Field Settings for Outdoor Unit
In case of heating operation the condense temperature is allowed to go up to 115°F (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.
 To activate the quick comfort setting under cooling operation, change field setting [2-81] to 2.
 To activate the quick comfort setting under heating operation, change field setting [2-82] to 2.
• 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 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 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.
 To activate the mild comfort setting under cooling operation, change field setting [2-81] to 1.
 To activate the mild comfort setting under heating operation, change field setting [2-82] to 1.
• 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 eco comfort setting under cooling operation, change field setting [2-81] to 0. This
 To activate the eco comfort setting under heating operation, change field setting [2-82] to 0. This
No matter which control is selected, variations on the behavior of the system are still possible due
to protection controls to keep the unit operating under reliable conditions. The intentional target,
however, is fixed and will used to obtain the best balance between energy consumption and
comfort, depending on the application type.
