Sequence of Operation
8. Timer
The unit can be controlled by a timer. It will be switched on or off automatically.
8.1 TIMER ON
8.1.1 TIMER ON can be set only when the air conditioner is OFF.
8.1.2 Press TIMER on the remote control ONCE to enter time setting.
8.1.3 Press "+" or "- " to set the time for unit to start
8.1.4 Set other function as MODE, FAN SPEED, SWING etc.
8.1.5 Press TIMER ONCE AGAIN to confirm the TIME ON setting
8.2 TIMER OFF
8.2.1 TIMER OFF can be set only when the air conditioner is ON.
8.2.2 Press TIMER on the remote control ONCE to enter time setting.
8.2.3 Press "+" or "-" to set the time for unit to stop
8.2.4 Press TIMER ONCE AGAIN to confirm the TIME OFF setting
Note: In case of no selection for the time setting within 10s, the timer function will be OFF automatically.
9. Sleeping mode
While AC works in sleeping mode, the light of POWER SUPPLY and SLEEP always ON, and the temperature display will be OFF
after 15s.
In this mode, the AC unit works according to the SLEEP CURVE as designed.
Sleeping mode the unit can work 10 hours continuously, after that it will quit from this mode and work as previous presetting.
10. Auto restart function
While unit is operating in one mode, all of its operation data, such as working mode, preset temperature etc., is memorized into
IC by main PCB. If the unit lose power, the AUTO RESTART function will set synchronously and the air conditioner will work at
the same mode as before once power is restored.
Note: The function setting: Within 3 min of turning the power ont, set the unit in cooling mode, set temperature to 86˚F, and mid
fan speed, press the ECO button 10 times within 8s, the AUTO RESTART will be activated.
11. Over heat protection for Heating mode
11.1 Overload protection
11.1.1. Overload protection for Cooling or Dry mode
11.1.1.1 if:
11.1.2 When OPT≥131˚F, the compressor will be frequency limited/reduced for over load protection.
11.1.3 If the unit faults 6 times for overload stop working protection continuously, this protection can't be recovered
unless ON/OFF button is pressed,. The unit will show failure code.
In the process of operation, once the compressor runs continuously more than 6 min, the counter of overload stop
working protection will be reset to zero and start a new counting process.
The failure protection will be reset when the unit is switched off or placed in fan mode.
NOTE: If the defective failure can't be recovered, the failure can't eliminate even if operation mode changed.
11.2 Overload protection for Heating mode
11.2.1 If:
a. IPT≥144˚F, unit stops working for overload protection.
b. IPT<131˚F, after compressor stopps for 3 min, the unit can be restarted.
11.2.2 When IPT≥131˚F, the compressor will be frequency limited/reduced for over load protection.
11.2.3 If unit has 6 times of over load stop--working protection continuously, this protection can't be recovered unless
ON/OFF button is pressed, and unit will show failure code.
In the process of operation, once the compressor runs continuously more than 6 min, the counter of over load stop
working protection will be reset to zero and start a new counting process.
The failure and times for protection will eliminate immediately once the unit to be switched off, on fan mode or changed
to be heating mode from others.
Note: If the defective failure can't be recovered, the failure can't eliminate even if operation mode changed.
