minutes after startup and also can’t be started again at least 3 minutes later after
shutdown. There are 3-minute protection with power on for the first time (over 3
minutes with power off). The compressor must be started again 3 minutes later after
shutdown.
There is no 2-minutes limit when changing the temperature setting or shutting off the
machine through the remote controller, and the machine can be shut down
immediately.
Avoiding electrical shock: outlet air is available 2 seconds later after startup.
Timer on, Timer off and sleep control are available.
Control of 4-way valve: When the unit is started for the first time, the 4-way valve starts
runnig 10 seconds earlier than compressor does. After compressor stops runnig, the
4-way valve continues running for 2 minutes and 30 seconds then stops. If changing
the unit from heating to cooling, the 4-way valve is shut off 2 minutes later and
compressor is started 3 minutes later.
Cold blast avoidance mode:
(1)Compressor is interrupted during the defrosting operation and continues to run after
defrosting is completed. When the indoor exchanging temperature is below 23℃,
the indoor fan motor is off. When the indoor exchanging temperature is above 23℃,
the indoor fan motor is running at weak speed.
(2)If the temperature of coil pipe can’t be above 38℃ 4 minutes later after startup, fan
motor is running at the preset wind speed.
(3) If the temperature of coil pipe is above 38℃ in 4 minutes after start up, fan motor
is running at the preset wind speed immediately.
(4)If coil pipe descends to the temp. lower than 38℃ from 38℃. fan motor still
running at the preset wind speed.
(5)If the temperature sensor is off. Compressor stops runnig. If the temperature of coil
pipe is above 23℃, fan motor enter breeze mode; and if the temperature of coil
pipe is below 20℃, fan motor stops running.
(6)Shut down the unit and indoor fan motor stops running.
High temperature protection and high temperature expiration protection:
z High temperature prevention: When the temp. of coil pipe is above 65℃, the
outdoor fan motor stops.When the temp descends to 60℃, the outdoor fan motor is
restarted and fan speed invertage frequence is more than 45 seconds. High
temperature expiration prevention: When the temp. of coil pipe is above 72
℃,compressor and outdoor fan motor stop running 2 seconds later, and inlet air
runs as the temp. sensor is off. When compressor stands by for 3 minute and the
temp. of coil pipe is below 64℃, the unit can be started again.
Current protection and current expiration protection: (Not detecting within 60 seconds
after startup)
z Current protection: If current detected is above (CT1) and lasts 10 senconds
continuously, outlet air stops. If current detected is below (CT2) , outlet air is
regained。Current peak expiration protection: If current detected is above (CT3) , 3
seconds later the system enter current cross protection, compressor and air outlet
stop and start again 3 minuts later, and air inlet runs as the temperature sensor is
