Commercial Air Conditioner
Model: AU182AFERA
AD182AMERA, AS182AVERA
electrified for the first time, enter heating mode or defrosting is over, if heat exchanger temp. is
below 25.2
℃
and over 16
℃
, fan speed is ultra low; if heat exchanger temp. reduces below 23
℃
, fan motor speeds.).
3) When heat exchanger temp. rises, fan speed will be ultra low and low state, if 4 minutes
later, heat exchanger temp. can not enter the last period, fan speed will rise up to the last speed.
When up to the set speed, 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 25.2
℃
, indoor motor
stops; if coil temperature is over 25.2
℃
, fan motor will be in low speed, after the fan time is over
50 seconds, if coil temperature is over 28
℃
, fan motor will be in low speed; if coil temperature is
below 23
℃
, 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.
