Page 31: Operation Details
App1 Operation Details Summarization This specification is used for E、 Q、 SA series whose capacity is 9000-24000 btu and lower one, this standard book include all of the functions of 9000-24000btu and lower styles , but to the single unit , it not always all of the functions, the specific functions need to correspond corresponding modes to decide, this specification’s contents include same parts as below: 1、the basic condition of electrical control using... - Page 32 7、the four-way valve working electricity less than 1A/220V; 8、the swing motor is DC12V, four-phase eight clap step motor ; 9、the compressor is single power, the normal working electricity less than 1.5A; partition of electrical control’s function controller’s function constitute by some parts below: 1、...
- Page 33 Main function instruction 1、proper noun and expression TA: indoor environment temperature TE: indoor evaporator temperature TS: setting temperature 2、mandatory switch when the air conditioner under the opening condition, press this button is closing phenomenon; when the air conditioner under the closing condition ,press this is opening phenomenon, and after opening...
- Page 34 setting the temperature by remote controller, the control scope of temperature is 16℃～32℃, press the “up”、 “down” button can adjust the temperature. Press the “wind speed choose” button can choose the automatic wind、high speed wind、middle speed wind、low speed wind. Under this mode ,the four-way valve closed. 5、drying mode under this mode ,the four-way valve always closed, the control scope of temperature is 16℃～32℃.
- Page 35 outdoor fan operation、valve circuit have power、indoor fan open, and when satisfy the condition in the same time, the electric heating open. 9、intelligent defrost function When this mode operation , the conditioner begin to defrost if satisfy the condition, the sleeping light flicker. 10、sleep control function when automatic、...

Cooling operation sleeping: Setting temperature rise1℃ again rise1℃ original setting temperature 7h （sleep finish， close） Heating operation sleeping： Setting temperature original setting temperature drop2℃ drop2℃ again 7h（sleep finish，close） 11、 timing control function The longest timing time is 24h, unit is 1min, single timing way, change the mode not cancel the timing function, after setting the timing mode, pointing light lighten.
- Page 37 ③ Setting the “on” timer time Just setting under condition of the air conditioner closed, the timing scope is 1min~12h, divide 12h a.m. and 12h p.m., when arriver the setting time, the conditioner automatic open. Open or close the conditioner after setting timing, the intrinsic timing and sleeping automatic cancel.
- Page 38 Note: the nixie tube just display homologous fault code, if not have the nixie tube and just have the timing light, so the timing light point homologous fault code. When the indoor fan motor add the voltage, if not detection pulse signal which feedback by the indoor fan motor, close the output voltage of power supply to the indoor fan motor on the remote controller , after standby 30s, offer the voltage to the indoor fan motor again, if also not...
