Basic Functions
It will delay 3 minutes for restarting unit after compressor is stoped.
Cooling Mode
Cooling Conditions and Process
When T amb. Tpreset , the unit will run under cooling mode, in which case the compressor \ indoor fan and outdoor fan
will start , the indoor fan will run at setting speed.
When T amb. Tpreset 2 , the compressor will stop, the outdoor fan will atop running after 30 seconds,the indoor fan will
run at setting speed.
When Tpreset 2 T amb. Tpreset+1 , the unit will maintain its original operating status.
Under this mode, the switchover valve will not be powered on, and the setting temperature range is16 ~30 .
Protection
Antifreeze Protection
When the antifreezing pretection is detected,the compressor will stop,the outdoor fan will stop after 30s , the
indoor fan motor and swing fan motor will run at original run conditions under the cool mode.Indoor fan motor
will run at low speed and indoor fan motor will run at oroginal conditions under the dehumidify mode.When ant
-ifreezing protection is eliminated and the compressor has stopped for 3 minutes,the whole unit will run in the
oroginal mode.
Overcurrent protection
If total current is high,the compressor wil run in limited frequency.If total current is over the stop-running current,then the
compressor will stop,the outdoor will delay 30 seconds to stop.
DRY Modes
The conditions and process of DRY
When T amb. Tpreset , the unit will run under DRY mode, in which case the compressor \indoor fan and outdoor fan
will be started and the indoor fan will run at low speed.
When Tpreset 2 T amb Tpreset , the unit will run with original setting.
This manual is applicable to DC inverter Trendy Series: GWHD09A3NA31A, GWHD12A6NA31A.

When Tamb. Tpreset 2 , the compressor will be stopped, and outdoor fan will be stopped after 30 seconds,the indoor fan
will run at low speed.
Under this mode, the switchover valve will not be powered on, and the setting temperature range is 16 ~30 .

The conditions and process of heating
When Tamb Tset 2 ,the system enters heating running, in this case, the reversal valve, compressor,
out fan enter simultaneously running.The indoor fan will run with setting fan speed and anti-coolwind will be runned.
When Tamb Tset 5 ,the compressor will stop, and outdoor fan will be stopped in 30 seconds,the indoor unit
will run at setting fan speed for 60s then will stop .The switchover valve will be powered off after compressor is
stopped for 2 minutes under heating-off mode or the condition that heat is changed to other modes
Under this mode, the switchover valve will be powered on, and the setting temperature range is16 ~30 .

Running Stopping
Under Heat mode, due to the malfunction, the compressor will stop, indoor unit will blow surplus heat.
Under this mode, the system will accord to temperature change to automatically select its running mode (Cool, Heat, Fan). The
protection function is the same with that under Cool, Heat mode. When ambient temperature has changed, firstly will switch the
mode. After compressor started up, there is no 6mins delay at least.
Under this mode, indoor fan could select High, Medium, Low and Auto running, compressor, outdoor fan and 4-way valve will
stop to run.
Under this mode, the temperature setting range is 16-30 .
When total current raise up, the frequency drop protection
When total current is high, compressor will run in limit frequnt or drop frequent; If total current exceeds the current value of unit stopping,
the compressor will stop running, outdoor fan will stop after 30s delay.
Indoor fan stops running, compressor rotate to 25Hz (mechanical frequency) running, after 75s later, outdoor fan will stop, the
4-way valve will stop running; After compressor raise frequency to the defrosting frequency for defrosting. When compressor
defrosting has 8mins, or Tout pipe 10 , compressor will turn to 25Hz running,75s later, 4-way valve will start up, outdoor
fan will start up, compressor will turn to oil return frequency for running, indoor fan will run accord with anti-cool wind condition,
the displayer board temperature will display H1 (Only for the unit, which has indoor temperature display).

Timer control
The unit is turned on or off according to the timer set by the remote controller.
Sleep function
When the air conditioner is in Cool or Dry mode, after Sleep mode has been set properly, the preset Tset will
be increased by 1 after the sleep program has run for 1 hour, and Tset will be increased by another 1 after
2hours. Tset has been increased by 2 totally in two hours. Then the unit will run at this set temperature and the
set speed.
When the air conditioner is in HEAT mode, after Sleep mode has been set properly, the preset Tset will be
decreased by 1 after the sleep program has run for 1 hour, and Tset will be decreased by another 1 after
2hours. Tset has been increased by 2 totally in two hours. Then the unit will run at this set temperature and at
the set speed.

Buzzer
The controller is powered on and detect the signal received, the buzzer will beep.
When module is in protection, the compressor will stop. It will resume running after stopping for 3mins.
During the period of module protection, there will display malfunction in indoor unit and total
unit will stop running.
There have communication mulfunction when unit don't receive the corrrect signal for 3 minutes, the unit will
stop running.
When the temp. is over the standard, then compressor stop running. When the discharge temp. resume the
original conditions and compressor has stop running for 3 minutes, the compressor will resume running.
When tube temp. is detected high, the compressor runs in limited frequency or slow-frequency. When the temp. is over standard, then
compressor stop running. In auto Heat or Heat mode, the indoor fan will blow for 60s and then stop. In other modes, the indoor fan will
