9. PCB function:
NOTE: Ts is the set temperature, Tr is indoor room temperature, TP1 is indoor coil pipe temperature, TP2 is outdoor
coil pipe temperature.
Display panel
[1]only two LED
①running lamp(green)：power on light, flash one time/ one second during anti cooled wind.
②timer lamp(yellow)：only light at timer state.
[2]eleven LED
①running lamp(green)：power on light, flash one time/ one second during anti cooled wind.
②temperature lamp(green)：16～31℃set temp. and room temp. display, light is set temp. flash is set temp.
[3]two LED and two 8LED
①running lamp(green)：power on light, flash one time/ one second during anti cooled wind.
②timer lamp(yellow)：only light at timer state.
③8LED display set temp., also it can display timer time and failure code.
[4]LED multi-colour panel
①according to display mode: dehumidification, cooling, ventilation, heating, auto, sleep, fan speed, swing, timer, indoor

Cooling
●Start up the compressor: when the room temperature is more than Ts+1℃, compressor →start-up
●Shut down the compressor: when the room temperature is less than or equal to the set temperature Ts-1℃,
compressor →shutdown
●When the temperature of coil pipe of the indoor units is less than or equal to 1℃for one minute and the
compressor has continuous run for more than ten minutes, the compressor and outdoor blower fan shut down
through the electric control board and the indoor blower fan is running at low speed.
●When the temperature of coil pipe of the indoor units is more than or equal to 7℃and the compressor has
shutdown for more than three minutes, the compressor and outdoor blower fan start to run and the indoor blower
fan is running at set speed.
●When the temperature of coil pipe of the indoor units is equal to or less than －10℃for three minutes in the
compressor has continuous run for three minutes, the compressor, indoor and outdoor blower fans and swinging
wind shut down. Restart up six minutes later; if the above situations appear again within six minutes, all the
outputs are shut down through the electric control board and display failure.
●When you press turbo button of remote, the air conditioner enter turbo running, compressor and outdoor blower
fan turn on all along, indoor blower fan run at high speed, turbo indication is light.
●After the compressor runs five minutes, the lamp flashes 4 times per six seconds or display E4 if the temperature
of indoor coil pips is more than 25℃in the continuous 20 minutes. The controller will automatically shut down if
the temperature of indoor coil pips is more than 25℃in another continuous 20 minutes, that is the abnormality
protection of outdoor units and the indicator lamp keeps its former state of flashing. If the temperature of indoor
coil pips is less than 25℃in the second 20 minutes or the compressor shuts down, the electric control board will
store to the normal display and the time is restarted when starting up the compressor next time.
