restarted until 3 minutes later after it is reenergized.
10 Power breakdown memory
If the machine suddenly loses power while running, or stops for maintenance or trouble
shooting, it will restart running as the status when it stops after the power is restored.
Note: 1.
Function setting: Continuously press sleep button on the remote controller 10
times in 5 seconds and buzzer on control panel shall beep 4 times.
2. Memory content: Running mode, wind speed setting, temperature setting,
swing status.

(11) Control of water pump
a. In cooling (including automatic cooling mode) and dehumidifying modes, the water
pump works if the compressor runs while stops 5 minutes later after the compressor
stops.
b. When water tank is fully filled, the float switch will be off. The water pump will start
to work after a controller has detected this signal and it will continue working for 5
minutes after the float restores to normal state.
c. If the full water signal is detected continuously over 5 minutes, the water pump
indicator lamp will flash to alarm and compressor stops running. The water pump
will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until
the float restores to normal state, after which the pump will run for 5 minutes then
stop.
(12) Monitoring of remote network
Through preset interface, the air conditioner is connected to remote control detector
(made by Haier) with 2-core cables for wire communication, to execute instructions sent
from computer or centralized controller via remote control detector and meanwhile send
present running status and trouble information of the machine to remote control detector.
Connection between air conditioner and remote control detector:

(13) Trial run
Under shut-down state, hold pressing mandatory button. The buzzer will beep once,
then twice after 5 seconds. Release the button to enter mandatory cooling mode, under
which the indoor blowing fan runs at high speed with both the compressor and outdoor
blowing fan working. Press the mandatory button again can end the mandatory mode.
