SiUS342303E Field Setting from Outdoor Unit
Part 5 Field Settings and Test Operation 216
 To activate this setting under heating operation: change field setting [2-9] to the appropriate
value, matching the requirements of the pre-designed system containing a high sensible
solution.
2.6.2 Comfort Settings
A comfort level can be set for VRT control mode and hi-sensible mode. The comfort level is related
to the time and power (energy consumption) expended in order to achieve a certain room
temperature. The requested conditions are achieved more quickly by temporarily changing the
refrigerant temperature.
• Powerful
Overshoot (during heating operation) or undershoot (during cooling operation) is allowed compare
to the requested refrigerant temperature, in order to achieve the required room temperature very
fast. The overshoot/undershoot is allowed from the start up moment.
In case of cooling operation the evaporating temperature is allowed to go down to 37°F (3°C) on
temporary base depending on the situation.
In case of heating operation the condense temperature is allowed to go up to 120°F (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.

To activate the powerful comfort setting under cooling operation, change field setting [2-81] to 3.
 To activate the powerful comfort setting under heating operation, change field setting [2-82] to
3.
• 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/undershoot is allowed from the start up moment.
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.
 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/undershoot 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.
