3 FUNCTION

Function Description

Memory function

when unit restarts after power off, it will run on former status, the mode and

parameter are kept the same

Remote control function

wireless controller and remote controller can be selected, and the maximum

control distance of remote controller is 10m.

Timing function

it can timing ON/ OFF separately, meanwhile, it can also timing on circularly

Self-diagnosis with

alarm function

Once the unit has malfunction, the malfunction code will be indicated and alarm

rings immediately

Sleep function it can self control for saving energy in energy saving mode.

Automatic function

the fan of indoor unit can adjust fan speed automatically based on actual

demand when cooling or heating under automatic mode

Cool air proof function

the fan starts only when the temperature of indoor unit heat exchanger is higher

than indoor temperature under heating mode

Weekly Time

Centralized Control and Weekly Timer Functions: The centralized controller and

the weekly timer are integrated in the same wire controller. The system has both

the centralized control and the week timing functions. Up to 16 sets of units can

be controlled simultaneously by the centralized controller (weekly timer). The

weekly timer has the function of invalidating the lower unit. The weekly timing

function is able to realized four timing ON/OFF periods for any unit every day, so

as to achieve fully automatic operation. No timing control can be set for holidays.

High/low pressure

protection

when suction pressure is too low or discharge pressure is too high, compressor

will stop and unit display malfunction code

Overload protection

compressor has its own overheat protection.Once the temperature of

compressor is higher than allowable level, compressor will stop and only when

temperature recovery, compressor restart

Over current protection

once the current of compressor is higher than normal level, compressor will stop

and unit display malfunction code

Discharge high

temperature protection

once the discharge temperature of compressor is higher than allowable value,

compressor will stop and unit display malfunction code

Reverse (open) phase

protection

once the phase sequence of power supply is incongruent or the phase is absent,

unit can’t work.

Anti-high temperature

protection

once the heat exchanger temperature of indoor unit is too high, the outdoor fan

motor will stop.

Timing ON/OFF display

After the cooling command is sent out, the indoor fan will run at high speed for 5 seconds before it is put into
operation according to the setting. Then, it is started to calculate the system load demand value. If the load is 0, the
other loads except the indoor fan will not be put into operation (The water pump will run according to the pump
control logic behind). If the load is >0, the EXV will be firstly opened to step X; then the indoor fan is started. After 30
seconds, the compressor is started at initial frequency 40Hz and will be maintained for 3 minutes. After that, the
compressor, EXV and outdoor fan will adjust according to logic.

When the heating command is sent out, it is started to calculate the system load demand value. If the load is 0,
all the loads will not be put into operation. If the load is >0, the EXV will be firstly opened to step Y; then the outdoor
fan is started. After 30 seconds, the compressor will increase its frequency to the required initial frequency 40Hz
before it started. It is started to count the time when the compressor frequency is increased to 20Hz. After 10
seconds, the 4-way valve is energized and then the indoor fan will run as per cold air prevention mode. The
compressor will keep running at initial frequency for 3 minutes. After that, the compressor, EXV and outdoor fan will
