Speed operation
Max capacity restriction
▪ Purpose
Enabling this setting will command the air conditioner to cool/heat faster at initial start-up.
▪ Concept
The cooling or heating speed is increased by raising the compressor frequency increase speed.
▪ Control specifications in detail
- The frequency and increase speed are increased in Safety Start mode.
- The control speed is improved by changing the interval to control the target heating pressure to 20 sec from 40 sec.
▪ Purpose
Prevent an excessive increase of compressor performance compared to the capacity of indoor units (default option).
▪ Concept
The maximum capacity for outdoor units is restricted taking into account the capacity of indoor units and the outdoor
temperature.
▪ Control specifications in detail
- The maximum operation capacity is restricted, taking into account the capacity of indoor units, set fan speed, outdoor
temperature, and indoor temperature if the system cooling operation status is within the normal operation range.
- The maximum cooling capacity is not restricted if the outdoor temperature is low and it is difficult to secure low and
high pressures.
▪ Notes
- This function will not work when High-head condition setting or Long-piping condition setting is enabled.
