3.4 TIMER Function
● General timer
a) TIMER ON: It can set timer on when the system is off, the setting time range is 0.5h-24h, when the time of setting timer on
reaches, and the system runs with the previous setting mode.
b) TIMER OFF: It can set timer on when the system is on, the setting time range is 0.5h-24h, when the time of setting timer off

when the system is on, when the time of timer off reaches, the system stops to run.
3.5 Memory Function
The system memories the setting running status of previous power-off, and runs automatically with the setting running status before it
power-off when it is energized again. If the unit is on before power-off, the compressor will 3min delay protection when it is energized
again.
3.6 Indicator Lamp, dual-8 digital pipe
a) When the unit runs, under cooling mode, cooling indicator lamp lights, dual-8 displays preset temperature.
b) When the unit runs, under fan mode, fan indicator lamp lights, dual-8 does not display.
c) When the unit runs, under dry mode, dry indicator lamp lights, dual-8 does not display.
d) When the unit runs, under heating mode, heating indicator lamp lights, dual-8 displays preset temperature.
3.7 Setting button function
a) ON/OFF button: It controls system's switch.
b) Mode button: Mode setting cycle with below sequence: Cooling only unit: cooling-> dry-> fan.
c) Temp. ▼ button: Set temperature when the unit is on, the setting temperature decreases 1
Temp. ▼ button; it will never setting when the setting reaches to 16
d) Temp. ▲ button: Set temperature when the unit is on, the setting temperature increases 1
Temp. ▲ button; it will never setting when the setting reaches to 30
3.8 Light Control
If set the light is on with remote control, the indicator lamp and dual-8 display the current setting status; if set the
light is off with remote control, turn off the lamp immediately. If there is front panel button or remote control button

● Anti-freeze Protection
When the anti-freeze protection is inspected, the compressor stops, fan motor runs with setting fan speed.
When the anti-freeze protection is canceled and reaches to the 3min time-delay, it runs with the original status.
Temperature sensor failure inspection
a) Environment temperature sensor is open, short circuit: dual-8 displays F1, the cooling indicator lamp goes out 3S and blinks 1
time, and it will light up 0.5S and go out 0.5S when it is blinking.
b) Indoor pipe temperature sensor is open, short circuit: dual-8 displays F2, the cooling indicator lamp goes out 3S and blinks 2
times, and it will light up 0.5S and go out 0.5S when it is blinking.
c) Outdoor pipe temperature sensor is open, short circuit: dual-8 displays F4, the cooling indicator lamp goes out 3S and blinks 4
times, and it will light up 0.5S and go out 0.5S when it is blinking.
d) The compressor or electric heating pipe stops when the temperature sensor failure and the unit is on, The fan motor will be deal
regarding compressor or electric pipe reach to the temperature point and stops.
● Over current Protection
If the system current is inspected too large for 3min continuously, the fan motor runs with setting conditions, other load stops; 3min
later, the unit runs with the previously status; if over current protection occurs for 6 times continuously, display error code "E5", the
load stops this time; if block the button except ON/OFF button, it will remote control the unit to off then on, or turn off with button, or
re-energized; the time of over current protection will zero clearing with remote control, press to turn on or re-energized.
● Over-flow Protection
If the over-flow is detected for 3S, it will enter into over-flow protection. Display error code H8, heating indicator lamp or over-flow
indicator lamp goes out 3S and blinks 8 times.
