Follow Me Feature (on some models)
This feature can be activated from the remote control only. The remote control serves as a remote thermostat
allowing for the precise temperature control at its location. ( )
To activate the Follow Me feature, point the remote control towards the unit and press the Follow Me button. The
remote display is actual temperature at its location. The remote control will send this signal to the air conditioner
every 3 minutes interval until press the Follow Me button again. If the unit does not receive the Follow Me signal
during any 7 minutes interval, the unit will beep to indicate the Follow Me mode has ended.

2.1 Terms and definitions
 TA: Temperature of indoor ambient (T1)
 TE: Temperature of evaporator (T2).
 TS: The set temperature.
 DAHT: Sensor of heater
2.2 Protection function
 The compressor restart protection functions with a delay of 3 minutes.
 5 minutes operation for compressor(this function is for cooling and heat pump mode)
 Sensor protection at open or short circuit.
2.3 Auto mode
 At Auto mode, the unit will choose cooling, heating or fan-only mode according to ΔT =TA-Ts)
ΔT=TA-Ts Running mode
ΔT＞4F Cooling
-2F≤ΔT≤4F Fan-only
ΔT<-2F Heating (Setting temperature is TS-1F);
Or Fan-only (for cooling only models).
 The unit will choose actual operation mode in auto mode in the below cases:
 Power on or change mode to auto mode or adjust temperature in auto mode, the unit will choose actual
running mode again.
 A: On auto mode, if the compressor keeps not running for 15 minutes. judge condition B
B: If ΔT<-8℉ or ΔT ＞2℉, the unit will choose actual running mode again according to ΔT till the
compressor stops.
2.4 Fan-only mode
 The temperature can’t be controlled at the mode, and the room ambient temperature is display on LED.
 The Ion/ Timer functions are valid at the fan-only mode.
And follow me function (for some models) is invalid at fan-only mode.
2.5 Cooling mode
 The temp can be set from 62 to 86℉(17 to 30℃)
 The compressor will be activated by sensing the difference between setting temperature and the actual
ambient room temperature.
The compressor operates as below:

Operation conditon
compressor off with a delay of 1 minute
compressor on
When TA≤TS (lasting 1 minute), compressor off
When T1>TS+2℉, compressor on
 The Ion/ Timer/ Sleep/ Energy Saver/ Follow Me functions are valid at the cooling mode.
2.6 Auto-defrosting function protection as below:
 When TE is lower, it means that the evaporator frosts. Then the unit starts defrosting, and the indoor fan
keeps working at the moment. When the temperature is up, the unit stops defrosting.

2.7 Heating mode
 The setting temperature from 62~86℉(17~30℃)
 On heating mode, Lo/Mid/HI/Auto speed can be chose.
 When unit uses 115V heater for heating, it will operate at Low speed (on heating mode, the speed can’t
be controlled, it should be at Low speed by force).
 When unit uses 115V heater for heating, it will operate on Auto heat mode at low speed by force no
matter that the LED displays as Auto speed.
 On heating mode, ION/Sleep/Timer/Follow me function are valid.
 Heating operation is according to the difference between TS and TA. (figure as below)

2.8 Dry mode
 The temp can be setting as same as Cooling mode.
 The fan speed is low and can’t be controlled at the mode.
2.9 Sleep mode
 This function is 7 hours. It is valid in cooling, heating and auto mode.
 In this function the fan speed will be change to auto fan.
 In this function, the first and second 30minuts, the setting temp will up (or down for heating mode) 2℉ (1℃),
after that will keep 6 hours, until the function stop.
 When the function is start, if you do any operation below, the function will stop. Press sleep button again, or
use the remote control to set anything. Turn off the unit. It is time to turn off the unit, for timer off function.

4.2 Cleaning filter
Notice:
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the
filter can build up and cause an accumulation of frost on the cooling coils.

5 Troubleshooting
In general, possible trouble is classified in three kinds. One is called Starting Failure which is caused from an
electrical defect, another is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper
application, and the other is called the Structure Damage.
5.1 Troubleshooting
Problem Solution
Air conditioner does not
start
Wall plug disconnected. Push plug firmly into wall outlet.
House fuse blown or circuit breaker tripped. Replace fuse with time delay type or reset circuit
breaker.
Plug Current Device Tripped. Press the RESET button.
Power is OFF. Turn power ON.
Air from unit does not feel
cold enough
Room temperature below 62℉(17℃). Cooling may not occur until room temperature rises above
62℉(17℃).
Temperature sensing element touching cold coil, located behind air filter. Straighten tube away
from coil.
Set to a Lower temperature.
Compressor stopped when changing modes. Wait for 3 minutes after set to the COOL mode.
Air conditioner cooling, but
room is too warm- ice
forming on cooling coil
behind decorative front.
Outdoor temperature below 64℉(18℃). To defrost the coil, set FAN ONLY mode.
Air filter may be dirty. Clean filter. Refer to Care and Cleaning section. To defrost, set to FAN
ONLY mode.
Thermostat set too cold for night-time cooling. To defrost the coil, set to FAN ONLY mode. Then,
set temperature to a Higher setting.
Air conditioner cooling, but
room is too warm- NO ice
forming on cooling coil
behind decorative front.
Dirty air filter- air restricted. Clean air filter. Refer to Care and Cleaning section.
Temperature is set too High, set temperature to a Lower setting.
Air directional louvers positioned improperly. Position louvers for better air distribution.
Front of units is blocked by drapes, blinds, furniture, etc. - restricts air distribution. Clear blockage
in front of unit.
Doors/ windows/registers, etc. Open- cold air escapes. Close doors, windows, registers.
Unit recently turned on in hot room. Allow additional time to remove. Stored heat from walls,
ceiling, floor and furniture.
Air conditioner turns on and
off rapidly
Dirty air filter- air restricted. Clean air filter
Outside temperature extremely hot. Set FAN speed to a Higher setting to bring air past cooling
coils more frequently.
Noise when unit is cooling Air movement sound. This is normal. If too loud, set to a slower FAN setting.
Window vibration - poor installation. Refer to installation instructions or check with installer.
Water dripping INSIDE
when unit is cooling.
Improper installation. Tilt air conditioner slightly to the outside to allow water drainage. Refer to
installation instructions - check with installer.
Water dripping OUTSIDE
when unit is cooling.
Unit removing large quantity of moisture from humid room. This is normal during excessively
humid days.
Remote Sensing
Deactivating Prematurely
(some models)
Remote control not located within range. Place remote control within 20 feet & 180°, radius of the
front of the unit.
Remote control signal obstructed. Remove obstruction.
Room too cold Set temperature too low. Increase set temperature.
