General Functionality Si04-11528 Main Function1.9 General FunctionsPre-heatoperationWhen the equipment has stopped and t[outside] < 11.5°C, the compressor is warmed-up bypassing a single-phase (U, V phase) current through the compressor motor to speed up thestart. The power consumption is 30-40W.Hot start function During defrosting or when the thermostat is on in heating mode, the indoor heat exchangertemperature≥ 29°C to fan starts to avoid cold draft.Dry mode The dry mode removes humidity while maintaining the room temperature. The temperature andfan cannot be regulated during dry mode.1. Decision of the dry setting temperature" When entering the following dry mode, Stop → an operation will start with Dry. Mode except Dry → changing to dry modeThermostat ON/OFF point is decided in accordance with the following conditions.2. Frequency command" The frequency command is decided based on a room temperature zone.The room temperature zone is decided as follows.11.5˚C13.5˚COutsidetemperatureOFF ON OFFwarm-upcontrol forcompressor(R1911)Room temp. cond. at enteringDry.Set temp.
