Piping DiagramSamsung Electronics 251Current restriction rateƒ PurposeReduce the electric current used for operation.ƒ ConceptThe max electric current (50% - 100%) is restricted.ƒ Control specifications in detail- The maximum current for outdoor units is restricted according to the current ratio that was configured while in coolingor 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 ofoutdoor will increase.- To set no restriction, make sure to contact an expert install service provider.Outdoor units operate with an abnormal current.This may affect the power and operation. The electric current protective control remains on to protect the units.Input unit Seg1 Seg2 Seg3 Seg4 Current restriction rateIndividual 0 20 0 100% (default)0 1 95%0 2 90%0 3 85%0 4 80%0 5 75%0 6 70%0 7 65%0 8 60%0 9 55%1 0 50%1 1 No restrictionOil collection intervalƒ PurposeThe 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 NotesChange the option if an oil leak occurs. Performance may degrade if the option is not changed.Make sure to restore the original value after refilling the oil.Input unit Seg1 Seg2 Seg3 Seg4 Oil collection intervalMain 0 4 0 0 Standard (default)0 1 Shorten the interval by 1/27-3 Functions (cont.)7-3-3-1 Field Setting (cont.)7-3-3 Others (cont.)
