Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost. Action conditions of compressor at heating mode: compressor must run for 4 minutes after starting and then judge temperature. Meanwhile other protections are still valid.

Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan with 18 the compressor still running. Add up to 90 minutes . 8.5.2 Conditions of defrost ending: Defrosting ends when either of the following : The time gets to 10 minutes; T3>20°c 19 8.5.3 Time sequence of the whole defrosting procedure is as follows: Defrost 10or 6minutes 55S 55S Compressor 4-way Valve 50S 50S Outdoor Fan Indoor Fan 15S Remark: when the evaporator pipe sensor temp. more than TE16, The indoor fan start to run. 8.6 8.6.1 Auto mode When running in automatic mode, the air conditioner automatically selects one of the following operation modes: cooling, heating or ventilation according to the difference between room temp. (TA) and set temp. (TS). TA—TS Operation mode TA—TS>2℃ Cooling -1℃ ≤TA—TS≤+2℃ Air-only TA—TS<-1℃ Heating (air-only for cooling only type) 8.6.2 8.6.3 At auto mode, the indoor fan blows automatically in selected mode. One mode should be carried out for at least 15 minutes once selected. If the compressor cannot start for 15 minutes, reselect the operation mode according to the room temp. and set temp., or reselect when the setting temp. changed 8.7 Economic mode Cooling: The set temperature rise 1℃ per hour. Two hours later, the set temperature will maintain as a constant and the air circulation is kept at low speed,and the air condition will stop work after 7 hours. Heating: The set temperature decrease 1℃ per hour. Two hours later, the set temperature will maintain as a constant and the air circulation is kept at low speed, and the air condition will stop work after 7 hours. (Cold air proof function takes priority over all). 8.8 Manual operation Manual operation is controlled by touching buttons and divided into force cooling and forced auto mode. It transfers between these two modes by pressing the buttons, the cycling order of the button press is: Remote mode Forced auto Forced cooling 8.8.1 Forced Cooling 8.8.1.1 In forced cooling mode, the remote signal is not accepted. 8.8.1.2 The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan mode is set as low, the A/C operates in the forced auto mode under the requirements of the forced auto mode. 8.8.1.3 During the start-up and operation, all of the following protecting functions work: 3minutes start-up delay protection, overload protection, outdoor protection, evaporator Protection against low temperature. If any of the protection functions, the comparative protecting action is executed. The forced cooling mode is closed by one touch on the button, meanwhile the operation light is off, the buzzer buzzes lasts for 1 seconds, then A/C turns to be closedown status. 20 8.8.2. Forced Auto 8.8.2.1 Remote control signal can be received in forced auto mode. When receiving the signals, the forced auto mode will be canceled and the A/C changes to remote control status and performs operation as the signals indicates. 8.8.2.2 The system performs control according to the remote control auto mode with a set temperature of 24°c. 8.9 Timer 24 hours timer on or off. 8.10 Protecting Function 8.10.1 Compress with a delay of 3 minutes. 8.10.2 Sensor open and break protection 8.10.3 EEPROM error protection. 8.10.4 Current protection function.
