If Tamb.7preset +2°C, the unit enters heating mode, in which case the four-way valve, the compressor and the outdoor fan will operate
simultaneously, and the indoor fan will run at preset speed in the condition of preset cold air prevention.
If Tamb.7preset +5°C, the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will stop after 60-second blow

If Tpreset +2°C<Tamb.< Tpreset +5°C, the unit will maintain its original operating status.
Under this mode, the four-way valve is energized and temperature can be set within a range of 16~30°C. The operating symbol, the

ĸCondition and process of defrost
When duration of successive heating operation is more than 45 minutes, or accumulated heating time more than 90 minutes, and one of

ĺModule protection
Under module protection mode, the compressor will stop. When the compressor remains at stop for at least 3 minutes, the compressor
will resume its operation. If module protection occurs six times in succession, the compressor will not be started again.
ĻOverload protection
If temperature sensed by the overload sensor is over 115°C, the compressor will stop and the outdoor fan will stop with a time lag of 30
seconds. If temperature is below 95°C, the overload protection will be relieved°C.
ļDC bus voltage protection
If voltage on the DC bus is below 150V or over 420V, the compressor will stop and the outdoor fan will stop with a time lag of 30 seconds.
When voltage on the DC bus returns to its normal value and the compressor has stayed at stop for at least 3 minutes, the compressor will
resume its operation.

ķOperation pattern and mode pattern display
All the display patterns will display for a time when the power on, the operation indication pattern will display in red under standby status.
When the machine is start by remote control, the indication pattern will light and display the current operation mode (the mode light includes:
Cooling, heating and dehumidify). If you close the light key, all the display patterns will close.
ĸDouble-8 display
According to the different setting of remote control, the nixie light may display the current temperature (the temperature scope is from 16°C to
30°C) and indoor ambient temperature. The set temperature displayed in auto cooling and fan mode is 25°C and the set temperature displayed
in auto heating mode is 20°C. Under heating mode, nixie tube displays H1 or heating indicator is off 0.5s and blinks 10s in defrosting.(If you
set the fahrenheit temperature display, the nixie light will display according to fahrenheit temperature)

(12) Drying Function
You may start or stop the drying function under the modes of cooling and dehumidify at the starting status (The modes of automatism, heating
and air supply do not have drying function). When you start the drying function, after stop the machine by pressing the switch button, you
should keep running the inner fans for 2 minutes under low air damper (The swing will operate as the former status within 2 minutes, cooling
indicator is on for 0.5s and then off for 10s in drying and other load is stopped), then stop the entire machine; When you stop the drying
function, press the switch button will stop the machine directly. When you start the drying function, operating the drying button will stop the
inner fans and close the guide louver.
(13) Memory function when interrupting the power supply
Memory content: mode, swing function, light, set temperature and wind speed. After interrupted the power supply, the machine will start when
recovering the power according to the memory content automatically. If the last remote control command has not set the timed function, the
system will remember the last remote control command and operate according it. If the last remote control command has set timed function
and the power supply is interrupted before the timed time, the system will remember the timed function of the last remote control command,
the timed time will recounted form power on. If the last remote control command has set timed function, the time is out and the system is start
or stop according to the set time when the power supply is interrupted, the system will remember the operation status before the power supply
was interrupted, and do not carry out timed action; The timed clock will not remembered.
