1. Under heating mode: auto speed under heating or auto heating mode:
a. W hen Tamb<1°C(1.8°F), indoor fan will operate at high speed;
b. W hen 1°C(1.8°F)<Tamb<3°C(5.4°F), indoor fan will operate at medium speed;
c. W hen Tamb>3°C(5.4°F), indoor fan will operate at low speed;
There should be at least 180s operation time during switchover of each speed.
2. Under cooling mode: auto speed under cooling or auto cooling mode:
a. W hen Tamb>2°C(3.6°F), indoor fan will operate at high speed;
b. W hen Tpreset<Tamb<2°C(3.6°F), indoor fan will operate at medium speed;
c. W hen Tamb<Tpreset, indoor fan will operate at low speed
There should be at least 210s operation time during switchover of each speed.
(7) Buzzer Control
The buzzer will send a “Di” sound when the air conditioner is powered up or received the information sent by the remote control or there is
a button input, the single tube cooler doesn't receive the remote control ON signal under the mode of heating mode.
(8) Auto button
If the controller is on, it will stop by pressing the button, and if the controller is off, it will be autom atic running state by pressing the button,
swing on and light on, and the main unit will run based on the remote control if there is remote control order.
(9) Up-and-Down Swinging Control
W hen power on, the up-and-down motor will firstly move the air g g
deflector to o counter-clockwise, close the air outlet.
A fter starting the machine, if you don't set the swinging functi on,
heating mode and auto-heating mode, the up-and-down air deflector
will move to D clockwise; under other modes, the up-and-down air A
deflector will move to L1. If you set the swinging function when you start C1 B
the machine, then the wind blade will swing between L and D. The air D
1
C
deflector has 7 swinging states: Location L, Location A, Location B, Location C, D
Location D, Location L to Location D, stop at any location between L-D (the included angle between L~D is the same).
The air deflector will be closed at 0 Location, and the swinging is effectual only on condition that setting the swinging order and the inner
fan is running. The indoor fan and com pressor may get the power when air deflector is on the default location.
(10) Display
® Operation 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.
W hen the machine is start by remote control, the indication pattern will light and display the current operation mode (the mode light in­
cludes: Cooling, heating and dehumidify). If you close the light key, all the display patterns will close.
© Double-8 display
According to the different setting of remote control, the nixie light may display the current tem perature (the tem perature scope is from 16°C
(60.8°F)to 30°C(86°F)) and indoor ambient temperature. The set tem perature displayed in auto cooling and fan mode is 25°C(77°F) and
the set temperature displayed in auto heating mode is 20°C(68°F). Under heating mode, nixie tube displays H1 or heating indicator is off 0.5s
and blinks 10s in defrosting.(If you set the fahrenheit tem perature display, the nixie light will display according to fahrenheit temperature)(11)

H3: Overload protection of com pressor H5: Module protection PH: High-voltage protection PL: Low-voltage protection
P1: Nominal cooling and heating test P2: Maximum cooling and heating test
P3: Medium cooling and heating test P0: Minimum cooling and heating test
(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 dam per (The swing will operate as the D1 status within 2
minutes, 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. W hen you start the drying function, operating the drying button will stop the inner fans and close the guide louver.
(13) Memory Function
W hen interrupting the power supply memory content: mode, swing function, light, set tem perature and wind speed.
A fter interrupted the power supply, the machine will start when recovering the power according to the memory content automatically.
