7. Electronic Function 1.Temperature Parameters ◆ Indoor preset temperature (Tpreset) ◆ Indoor ambient temperature (Tamb.) 2.Basic Functions (The temperature in this manual is expressed by Centigrade. If Fahrenheit is used, the switchover between them is Tf=TcX1.8+32.) Once the unit is energized, the compressor shall never be restarted except 3mins interval at least. For the first energization, if the unit is at off status before power failure, the compressor can be restarted without 3-min delay. - Page 19 (3) Heating Mode (this mode isn’t available for cooling only unit) ① Heating Conditions and Process When Tamb. ≤Tpreset+2℃, the unit operates in cooling mode. Compressor and outdoor fan operate and indoor fan operates according to cold air prevention. When Tamb.≥Tpreset+5℃, compressor and outdoor fan stop operation, while indoor fan operates according to blowing residual heat.
- Page 20 (4) Fan Mode In fan mode, indoor fan operates at set fan speed, while compressor and outdoor fan all stop operation. In fan mode, the temperature setting range is 16～30℃. Display is displaying operation icon and set temperature. (5) Auto Mode In auto mode, the system will select the operation mode (cooling, hearing of fan mode) according to the change of ambient temperature automatically.
- Page 21 (7)SAVE Function ① In cooling mode, if press IONFilter+clock buttons on remote controller simultaneously, the controller will enter into SAVE mode. In SAVE mode, if press IONFilter+clock buttons on remote controller simultaneously again, SAVE function won’t be set again. ② If remote controller is set to display set temperature, dual-8 nixie tube display “SE”. ③...
- Page 22 Timer Change Although timer has been set, the unit still can be turned on/off by pressing ON/OFF button of the remote controller. You can also set the timer once again, and then the unit will operate according to the last setting. If timer ON and timer OFF are set at the same time during operation of the unit, the unit will keep operating at current status till OFF time reaches.
- Page 23 When Tpreset＜Tamb.＜Tpreset＋3℃, indoor fan operates at medium speed; When Tpreset-2＜Tamb.≤Tpreset, indoor fan operates at low fan speed; When Tamb. ≤Tpreset-2℃, indoor fan operates at quiet mode. ③ Auto fan speed is not available in drying mode Note: high speed, medium speed and low speed is to “notch 5”, “notch “3” and “notch 1” respectively. As for the switchover among high speed, medium speed and low speed, the unit should operates at every speed for 3minutes and 3s at least.
- Page 24 (9) Control of Left&Right Swing After energization, swing will be restored to the starting point firstly and then stop at the middle position. When setting left&right swing, swing blade has 7 statuses: left position ① , secondary left position ② , middle position ③ , secondary right position ④ , right position ⑤...
- Page 25 (14) Fahrenheit Display Function Niexie tube displays current set temperature. If the remote control signal is Fahrenheit, the temperature will be display by Fahrenheit. Set temperature range is 16~30℃（61-86℉）. Under auto mode, nixie tube displays 25℃（77℉）in cooling and fan, and 20℃（68℉） in heating. Cooling only controller only displays 25℃（77℉）. (15) Locked Protection to Indoor Fan If the indoor fan motor keeps low rotation speed for a continuous period of time after startup, the unit will stop operation and display “H6”.
