Outline of Functions (Outdoor unit) SiBE811001EB79 CONVENI-PACK6.1 Detailed Description of Functions (Outdoor Unit)(1) Startup control for air conditioning(1)-1 Startup control (in cooling)(1)-2 Startup control (in heating)(1)-3 Thermostat ON/OFF by cleaning Case of activating cleaning automaticallyCooling: Conducts cleaning on an idle machine when the thermostat of the individualindoor unit is OFF. Capable at operation mode = 0 - 35Heating: Conducts cleaning when the thermostat of all indoor units is OFF or at stoppingstatus. Under cleaning operation mode = 0, 74, 75 and 80 only. Shifts tooperation mode = 0, 29, 30 and 35 LP2 ≥ 0.588MPa & Air conditioning low pressureretry times < 2[Pump down startup] LP2 ≤ 0.588MPa & Air conditioning low pressure retrytimes ≥ 2 LP2 ≥ 0.392MPa & Air conditioning low pressureretry times < 2[Pump down startup] LP2 < 0.392MPa & Air conditioning low pressure retrytimes ≥ 2&&OR• Operation SW: ON• Remote controller: ON• Main DIP • SW2-3 (Rest air-conditioner after forced stop): OFF• No cleaning request from indoor unit• Air conditioning indoor unit requires thermostat ON• Total capacity of connectable indoor units for air conditioning≥4HP(in cooling), 3HP (in heating)• LP2 > 0.0098MPa• Compressor re-starting standby terminated (3-10 min)LP2: Pressure detected with lowpressure sensor [S2NPL]• Operation SW: OFF• Remote controller: OFF• Main DIP • SW2-3 (Rest refrigeration equipment after forced stop): ON• Cleaning request from indoor unit exists• Cleaning approval from outdoor unit exists• All air conditioning indoor unit requires thermostat OFF• Total capacity of connectable indoor units for air conditioning < 4HP,3HP (in heating)• Cooling: LP2 < 0.343MPa continues 2 min.• Heating: LP2 < 0.098MPa continues 2 min.• Low pressure protection for air-conditioner activatesThermostat OFF(Air-conditionercompressor OFF)Thermostat ON(Air-conditionercompressor ON)ORYesNo• LP2<0.588MPa• 60 sec. have passed• Opening degree ofindoor EV: 0 pls• Startup the compressorfor air conditioning• Outdoor unit directs indoor EV(Thermostat ON): 480-672 plsthen, is controlled by indoor unitORYesNo• LP2 > 0.588MPa continuesfor consecutive 15-30 sec.• 30-60 sec. have passedOpening degree ofindoor EV: 480-1920 pls• The Indoor EV is controlled byan indoor unit simultaneously atcompressor startupORYesNo• LP2 > 0.3724~0.588MPa• 60 sec. have passed• Opening degree ofoutdoor EV1: 0 pls• Startup the compressorfor air conditioning• Instructs outdoor Y1E_pls = 150pls. Subsequently becomescompressor suction SH.ORYesNo• LP2 > f(Ta) MPa• LP2 > 0.392MPaOpening degree ofindoor EV: 100-450 plsOutdoor Y1E becomes compressorsuction SH simultaneously atcompressor startup.The following conditionscontinue for consecutive10 to 30 sec.
