Description of Functions and Operation SiBE811001EB31 CONVENI-PACK4. Description of Functions and Operation4.1 Operating ModeThe fundamental mode of this system differs significantly between [Air conditioning (∗1) load]and [Refrigerating (∗2) load]. The compressor operation and status of outdoor unit heatexchanger for each mode are as follows:∗1. Air conditioning is defined as [Cooling] or [Heating].∗2. Refrigerating is defined as [Refrigeration] or [Freezing].{: Compressor operation —: No operation∗3. STD compressor 1 operates alternatively when INV. compressor is on standby or duringstop for an abnormal stop situation.∗4. STD compressor 2 operates alternatively when the STD compressor 1 is on standby orduring an abnormal stop.ModePartsCoolingonlyRefrigerationonlyCooling+RefrigerationCooling∨RefrigerationCooling∧RefrigerationHeatingonlyHeating+RefrigerationHeating∨RefrigerationHeating∧Refrigeration100%HeatrecoveryHeatingsurplusINV.
