●
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.

●
Start up the compressor: when the room temperature is less than Ts-1℃, compressor → start-up
●
Shut down the compressor: when the room temperature is more than or equal to the set temperature Ts+3℃,
compressor → shutdown
●
The electric heating start-up in the heating mode shall meet the following conditions: ① start up the
compressor and indoor blower fan ② none defrost ③ TP1< 49℃ ④Tr ≤20℃.
●
The electric heating shutdown in the heating mode shall meet one of the following conditions: ①
shutdown indoor blower fan ② Tr ≥ 23℃ ③ TP1≥50℃.
●
In the heating mode, the indoor flower fan can be set as high/ medium/ low /automatic running mode by
remote control however the anti cool air function is prior. In the heating mode, the anti cool air control
function is to control shutdown of the indoor blower fan by detecting the temperature of coil pipe of
evaporator so as to attain the purpose of preventing cold air from blowing.
●
For the waste heat emission function in the heating mode, in principle, the indoor blower fan shall be on for
fifteen seconds after the electric heating is closed.
●
When the temperature of coil pipe of indoor units is more than or equal to 56℃, the outdoor blower fan
shuts down and it enters the overload protection; when the temperature of coil pipe of indoor units is less
than or equal to 52℃, the outdoor blower fan starts up and it exit the overload protection.
●
When the temperature of coil pipe of indoor units rises to 63℃, the compressor and outdoor blower fan are

closed and two minutes later, the change valve is closed. The indoor blower fan is running at the set speed.
Restart up six minutes later; if the above situations appear again within ten 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 ,outdoor blower
fan and four-way valve turn on all along, indoor blower fan run at high speed and it must meet start
condition, 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 less than 30℃ (heating) in the continuous 20 minutes. The controller will
automatically shut down if the temperature of indoor coil pips is less than 30℃ in another continuous 20
minutes, that is the abnormality protection of outdoor units and the indicator lamp keeps its former state of

Defrost (only applicable to the heating mode)
1. the intelligent defrost
In the heating mode, the electric control board checks and compares the temperature of indoor room and indoor
coil pipe after the compressor works for a while; judge whether the outdoor heat exchanger part is frosted or not
according to conditions such as the change of indoor coil pipe temperature; if it is judged as frosted, it automatically
enters defrosting process. When defrosting, close the indoor and outdoor blower fan and four-way valve.
2. Outdoor PCB for defrost.
In the heating mode, the unit defrost by outdoor control board:
①unit start defrost shall all meet the following conditions:
a、compressor continuous running over 7 minutes;
b、defrost relay shut off;(-5℃)
c、compressor cumulate running time over 50 minutes.;
②first defrost interval time is 50 minutes, later defrost interval time decided by last defrost time.
