fan speed will stay at this state for 4 minutes and then adjust fan speed due to the heat exchanger temp.
4) When heat exchanger temp. reduces, if fan speed is low for over 4 minutes, the fan motor will go back to the
set speed.
2.2.2 3-minute protection when compressor stops
1) After compressor stops (thermostat is OFF), if coil temperature is below 25.2ć, indoor motor stops; if coil
temperature is over 25.2ć, fan motor will be in low speed, after the fan time is over 50 seconds, if coil
temperature is over 28ć, fan motor will be in low speed; if coil temperature is below 23ć, indoor motor will stop.
2) If the unit is shutoff by remote controller, indoor motor will stop after running at ultra low speed for 10 seconds.
2.2.3 Compressor restart up
After hot startup, the fan speed is the state set by remote controller.
When in Auto Fan mode, the air flow depends on the temperature.
2.2.4 In defrosting, after running at low speed for 20 seconds, fan motor stops. After defrosting is over, if
compressor stops, indoor motor will stop too. When compressor re-starts up, air flow can be set at High, Med,
Low according to the heat exchanger temperature.
2.3 Cooling operation
When in Auto Fan mode, the air flow will be confirmed according to the temperature.
2.4 Dry operation
2.4.1 If compressor is OFF, and in 3-minute standby:
1)Compressor stops, fan motor will stop too.
2)If 3-minute protection is over, fan is in ultra low state.
3)After 3-minute standby state, compressor will run.
2.4.2 If compressor is ON:
Fan motor will run at the set speed.
When in auto fan mode, the air flow will be adjusted due to the temperature.
3. Power operation (depend on the remote controller, not available for this model)
1) Power operation will keep for 15 minutes.
2) The unit stops or 15 minutes later, the power operation will stop.
3) If changing the operation modes, the power operation will stop.
4) If at soft mode or TIMER ON function works, the power operation stops.
5) In Auto mode, the Power/Soft function can work. In cooling mode, the unit will run at Cooling Power/Soft
mode. In heating mode, the unit will run at Heating Power/Soft mode. In Fan mode, there is no Power/Soft
function.
3.1 Power heating operation
1) Adjust the set temperature, can modulate the temperature.
2) Air flow is Auto Med speed.
3) In defrosting, outdoor unit will not the communication signal of power operation.
4) After Power operation works for 15 minutes, within 10 minutes, compressor can not be OFF, excluding the
failure condition.
3.2 Power cooling operation
1) Modulate the set temperature.
2) Air flow is Manual High speed.
3) After compressor is running, in 3 minutes, the unit will not make low load protection.
3.3 Not available for Fan, Dry mode.
4. Soft operation
The indoor unit will send the Soft operation signal to outdoor.
