Products powered by electricity should be serviced or repaired only by experienced professional technicians. [. . . ] These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit. When compressor is OFF (Thermostat OFF) and AUTO FAN is set, the fan will stop periodically. Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF point. Soft Dry Operation Thermostat control Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2. When compressor is OFF (Thermostat OFF) and AUTO FAN is set, the fan will stop periodically. Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF point. Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF point. During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the indoor intake air temperature. For the 2nd judgment onwards o If indoor intake temperature - remote control setting temperature ≥ 3°C, if previous operate in DRY mode, then continue in DRY mode. Fan motor’s number of rotation is determined according to remote control setting. remote control Tab ○ Hi ○ Me ○ Me○ Lo ○ QLo [Heating]  Fan motor’s number of rotation is determined according to remote control setting. remote control Tab ○ SHi ○ Me ○ Me○ Lo ○ QLo ii Auto Fan Speed [Cooling , Dry]  According to room temperature and setting temperature, indoor fan speed is determined automatically.  When set temperature is not achieved, the indoor fan will operate according to pattern below. fan Speed Higher Medium Lower a b c d e f g [1 pattern : 10 s] h a b  When set temperature achieved, the indoor fan speed will be fixed. According to indoor pipe temperature, automatic heating fan speed is determined as follows. Immediately after the fan motor started, feedback control is performed once every second.  During fan motor on, if fan motor feedback ≥ 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error counter increase, fan motor is then stop and restart. If the fan motor counter becomes 7 times, then H19 - fan motor error is detected. 3 Outdoor Fan Motor Operation Outdoor fan motor is operated with one fan speed only. It starts when compressor starts operation and it stops 30 seconds after compressor stops operation. oN Compressor: ON Outdoor Fan: 30 sec ON OFF Fan Speed OFF ON  During cooling operation, and outdoor ambient temperature is below 8°C, outdoor fan speed will be controlled according to outdoor piping temperature as following: OD Pipe Temperature A B 26°C 33°C  During above condition, when indoor heat exchanger temperature is below 5°C, the outdoor fan will stop according to outdoor piping temperature as following: 50 AMP Air Conditioning www. [. . . ] During operation of cooling and heating, when compressor tank temperature data (112°C) is detected by the compressor tank temperature sensor. 2/3 way valve closed  During operation of cooling and heating, when an input over-current (X value in Total Running Current Control) is detected by checking the input current value being detected by current transformer (CT) with the compressor running. 28 F99 (DC Peak Detection) Malfunction Decision Conditions During startup and operation of cooling and heating, when inverter DC peak data is received by the outdoor internal DC Peak sensing circuitry. Disassembly and Assembly Instructions WARNING High Voltage is generated in the electrical parts area by the capacitor. [. . . ]
