System Diagram
5.1 System Diagram for Cooling-and-Heating Unit
Capillary
4-way valve
Evaporator Condenser
Cooling Gas-liquid separator
Heating Compressor
Switch on the power to start the unit. Low-pressure refrigerant vapor from evaporator is absorbed into
the compressor, where it is compressed into high-temp. and high-pressure gas. The gas refrigerant is
then diverted to condenser, where it is liquidized after heat exchange with outdoor air. After that, the
liquidized refrigerant flows through capillary for decrease of temperature and pressure and then enters
into evaporator, where it becomes low-temp. and low-pressure refrigerant vapor after heat exchange
with indoor air to be regulated. This process is repeated in cycle to achieve the purpose of cooling.
(Under heating mode, the 4-way valve will change the flow of refrigerant, so that the condenser absorbs
heats and the evaporator gives out heats, thus to achieve the purpose of heating).

Controller and Remote Controller Function Manual and Operating Instructions
7.1 Controller and Remote Controller Function Manual 1
7.1.1 Temperature Parameters
◆Indoor preset temperature (Tpreset) ◆Indoor ambient temperature (Tamb.) ◆Outdoor condenser temperature (Tcond.)
7.1.2 Basic Functions
Under any mode, the compressor will keep running within 6 minutes once it is started (except under overfull protection).
Once stopped, it cannot be restarted until after 3-minute delay. When outdoor fan is started, run at high speed for 8
seconds and then switch to desired speed.
7.1.2.1 Cooling Mode
7.1.2.1.1 Cooling Conditions and Process
When Tamb. ≥T
preset +1℃, the unit will run under cooling mode, in which case the compressor and outdoor fan will be
started and the indoor fan will run at low speed.
When Tamb≤Tpreset -1℃, the unit will be stopped under cooling mode, in which case the compressor and outdoor fan will
be stopped and the indoor fan will run at preset speed.
When Tpreset -1℃<Tamb.< Tpreset +1℃, the unit will maintain its original operating status.
¾Under this mode, the switchover valve will be de-energized and the temperature can be set within a range from 16 to
30℃.
7.1.2.2 Dehumidifying Mode
7.1.2.2.1 Working Conditions and Process of Dehumidifying
When T amb.> Tpreset +2℃, the unit will run under cooling mode, in which case the compressor and outdoor fan will be
started and the indoor fan will run at low speed.
When Tpreset -2℃≤Tamb.≤Tpreset +2℃, the compressor, indoor unit and outdoor fan will run 6 minutes and stop 4 minutes
in repeated cycle, while the indoor fan will run at low speed.
When Tamb.< Tpreset -2℃, the compressor, outdoor fan and indoor fan will be stopped.
¾Under dehumidifying mode, the temperature can be set within a range from 16 to 30℃.

Auto Speed Low Speed Medium Speed High Speed
7.1.2.3 Heating Mode
7.1.2.3.1 Heating Conditions and Process
When T amb.≤Tpreset +1℃, the unit will run under heating mode, in which case the valve, compressor, outdoor fan and
indoor fan will run at preset speed under preset cold air prevention conditions.
If Tamb.≥Tpreset +3℃, the compressor and outdoor fan will be stopped, the valve is still energized and the indoor fan will
run at low speed.
When Tpreset +1℃<Tamb.< Tpreset +3℃, the unit will maintain its original operating status.
¾Under heating mode, the temperature can be set from 16 to 30℃.
¾If the unit is switched off under heating mode or switched from heating mode to another mode, the 4-way valve will
be de-energized 2 minutes after the compressor is stopped.
7.1.2.3.2 Defrosting Conditions and Process
When the condenser is detected to have frost, the system will enter into defrosting status and the guide louver will be
adjusted to level position. The auxiliary heater (if any) will be stopped firstly. After 1-minute lag, the compressor, indoor fan
and outdoor fan will be stopped. After 3 seconds, the 4-way valve will be closed. Thirty seconds after the 4-way valve is
closed, the compressor will be started and the defrosting begin. Upon completion of defrosting, the compressor will be
stopped and the 4-way valve will be energized. After 30 seconds, the compressor and outdoor fan will be started and the
indoor fan will run under cold air prevention mode.
7.1.2.3.3 Liquid Splash Protection
1. When the unit is put into heating mode for the first time or it is switched to heating mode from another mode, the
4-way valve will be energized and the indoor fan will run under cold air prevention mode 20 seconds after the
compressor and outdoor fan are started. If the unit is switched off under heating mode or switched from heating
mode to another mode, the 4-way valve will be de-energized 2 minutes after the compressor is stopped.
2. When the compressor is started for the first time, the exhaust temperature protection will be shielded for 1 minute.
7.1.2.3.4 Cold Air Prevention Condition
The indoor unit will firstly adjust the guide louver to level, while the indoor fan will run at low speed.
1. When up to UNIT ON temperature, the compressor will be started, the indoor unit will run at low speed and the guide
louver will remain at level position. After 30 seconds, the indoor unit will be switched to preset fan speed and the
guide louver will run as preset.
2. When lower than UNIT ON temperature, the guide louver will remain at level position and the indoor unit will run at
low speed.
7.1.2.4 Fan Mode
Indoor fan will run at preset speed
The temperature can be set within a range from 16 to 30℃.
7.1.2.5 Auto Mode
Under this mode, the system will automatically select the run mode (cooling, dehumidifying, heating and fan) depending
on the ambient temperature. Protection function is the same as under cooling and heating mode.
Thirty-second delay is provided for switching between different modes. (Every 30 seconds the system will detect if to
switch the mode).
