2. Functions and control panel.
The controls featured in this manual are representative of many available models. Your model
may offer slightly different features.
· POWER
- Press the POWER button to turn the unit on or off.
When the unit is on,the power indicator light will be green.When the unit is off,the light will go out.
· MODE
- Push this button to cycle through the modes from COOL-HEAT-FAN-COOL.The green indicator light beside the "MODE"
option will illuminate, identifying the mode selected.
- COOL:The range of set temperature is 17 ℃ /62 ℉ ~30 ℃ /86 ℉ .Cooling begins automatically when the room temperature is
above the set point,and stops when the room temperature is 2 ℃ (4 ℉ ) below the set point.But the compressor will run 5
minutes at least in COOL mode before stoping. The fan runs in continuous mode.
- HEAT:The range of set temperature is 17 ℃ /62 ℉ ~29 ℃ /84 ℉ .For heat pump models,the unit can alternate to run between in
reverse cycle heat mode and electric heater mode according to the difference between the setting temperature and the room
temperature.The fan motor cycles on and off with the compressor and electric heater.
NOTE: The reverse cycle and electric heater can not be run at the same time. In following cases, it is normal that the reverse
cycle does not operate.
1.When the outdoor temperatrue is lower than 4 ℃ /40 ℉ or the room temperature falls to 4.5 ℃ /8 ℉ below the set point
temperature.
2.There is a 3-minute minimum compressor run time at any setting to prevent short cycling. The indoor fan motors starts before
the compressor and stops after the compressor cycles off.
3.When frost builds up to the evaporator coils, the unit will defrost automatically and the compressor will cycle off.
- FAN:Fan operation only without heating and cooling.
5

UP/DOWN BUTTONS ( ▲ / ▼ )
- Push the UP (or DOWN) button to increase (or decrease) the set temperature of the unit in cooling
or heating mode.The temperature can be set by increments of 1 ℃ (1 ℉ ).The setting temperature
appears in the display.
NOTE:Press and hold ▲ and ▼ buttons together for 3 seconds will alternate the temperature display between ℃
& ℉ scale.
FAN (FAN SPEED)
- Every time you push this button, the fan speed cycles through the settings as follows: HIGH-MED- LOW-HIGH.
DISPLAYS:
- Shows the set temperature in ℃ or ℉ . While on Fan only mode, it shows the room temperature.
Control code:
LC-Pads on the control panel is not available. The unit can be set by using wire controller only.
Note: Whenreceiving the wired remote control signal display LC. Or when wired remote control signal is not
received within the panel key operation for 5 seconds to display LC
FC- Front desk control

ES- Open or short circuit of evaporator temperature sensor( T2 );
CS-Open or short circuit of condenser temperature sensor (T3);
oS-Open or short circuit of outside temperature sensor(T4);
HS- Open or short circuit of exhaust temperature sensor( T5 or T6);
Other codes:
LO-Room temperature is lower than 0 ℃ /32 ℉ ;
HI-Room temperature is higher than 37 ℃ /99 ℉
E4- Communication malfunction between main control board and display board
LE- Drive-by-wire controller failure
