Method of Field Set (Reset after Maintenance Inspection/Repair) Si-71A22 Explanation of Field Set1.4 Local Setting Mode No.Example To set the filter sign time to “filter contamination - heavy” for all units in a group:Set mode No. to “10,” setting switch No. to “0,” and setting position No. to “02.”TableNotes: 1. Setting is made in all units in a group. To set for individual indoor units or to check the setting, use themode Nos. (with “2” in upper digit) in parentheses ( ).2. The setting position No. is set to “01” at the factory, except for the following cases in which “02” is set.Ñ Setting of air flow direction adjustment rangeÑ Automatic restart after power outage.Ñ Remote control thermostatÑ Filter sign indication (only for ceiling-mounted duct type)3. When installing Sky Air simultaneous operation multi-unit, set to either “twin” or “triple.”Only when the factory setting is changed, it is necessary to make a setting using a remote controller.4. For further details, see the installation instruction.5. Since drafts may result, carefully select the installation location.6. When power returns, units resume the settings made before the power outage.ModeNo.Note 1SettingSwitchNo.Setting Description Setting Position No. *Note 201 02 0310(20) 0 Filter contamination - heavy / light(Setting of operating hours for filtersign indication) (Change settingwhen reducing filter sign indicationtime to half due to quick soiling offilter)Urtra-Long-Life TypeLight Approx.10,000hoursHeavy Approx.5,000hours—Long-LifeTypeApprox.2,500hoursApprox.1,250hoursStandardTypeApprox.200 hoursApprox.100 hours1 Long-life filter type (Setting of filter sign indicationtime)(Change setting when Urtra-long-life filter isinstalled)Long-Life Filter Urtra-Long-Life Filter(1) Setting DescriptionUrtra-Long-Life Filter(2)3 Estimation of filter operating hour(Change setting when filter sign indication is notused)ON OFF —11(21) 0 No. of Sky Air indoor units connected forsimultaneous ON-OFF multi system(Change setting when simultaneous operationmulti system is used) *Note 3Pair Twin Triple1 Simultaneous operation multi-unit individualsettingUnified Individual —2 Indoor unit fan OFF when cooling/heating is OFF — Fan OFF —12(22) 3 Change to set fan speed when heater thermostatis OFF *Note 5Fan Speed LL Set Fan Speed —5 Automatic restart after power outage reset*Note 6OFF ON —13(23) 0 HighCeilingCeiling-mounted built-in multi-flowcassette type, Ceiling suspendedcassette typeN H SCeiling-suspended type, wall-mountedtyp2.7 m or Lower 2.7~3.5 m —Fan speed increase (wall-mounted type) Standard Slight Increase Normal Increase1 Air flow direction selection (Change setting whenblocking kit is installed) *Note 4F T W3 Air flow direction adjustment (Change settingwhen decorative air outlet panel is installed)Installed Not Installed —4 Setting of air flow direction adjustment range Upward Standard Downward5 On-site fan speed change by air outlet (Whenusing phase control)Standard Option 1 Option 26 External static pressure setting (To be setaccording to connected duct resistance) (Highceiling setting in the case of FHYK)Standard (Standard) High Static Pressure(High Ceiling Setting) Low Static Pressure
