Current restriction rate
ƒ Purpose
Reduce the electric current used for operation.
ƒ Concept
The max electric current (50% - 100%) is restricted.
ƒ Control specifications in detail
- The maximum current for outdoor units is restri
cted according to the current ratio that was configured while in cooling
or heating mode.
- See "Maximum current limit (total)" for details.
ƒ Notes
- When
current restriction option is set, cooling and heating performance may decrease and power of
outdoor will increase.
- To set no restriction, make sur
e to contact an expert install service provider.
Outdoor units operate with an abnormal current.
This may affect the power and operation. The electri
c current protective control remains on to protect the units.

Oil collection interval
ƒ Purpose
The oil return cycle is shortened by half.
ƒ Concept
- Oil recovery is performed at the halved oil return interval.
- See "Oil return operation" for
details on oil return operation specifications.
ƒ Notes
Change the option if an oil leak occurs. Performance may degrade if the option is not changed.
Make sur
e to restore the original value after refilling the oil.
