8.2

Proper symbols and their meanings:

TA: Indoor ambient temperature

TE: Indoor evaporator temperature

TS: Setting temperature through the remote controller

3sec

: Self-protection amp of compressor, continue three seconds until turns off the compressor.

5MIN

: Self-protection amp of compressor, continue five minutes until turns off the compressor.

FAN

: Self-protection amp of outdoor fan/indoor fans when they change from higher wind to lower

wind.

RESTORE

: Amp self-protection return value

DEFROST

: High wind, defrosting temperature difference

DEFROST

: Middle wind, defrosting temperature difference

DEFROST

: Low wind, defrosting temperature difference

TE1: Anti-cold wind, from Fan Off to Breeze temperature

TE2: Anti-cold wind, from Breeze to Setting Fan Speed temperature

TE3: Anti-cold wind, from Setting Fan Speed to Breeze temperature

TE4: Anti-cold wind, from Breeze to Fan Off temperature

TE5: Evaporator low temperature protection entering temperature

TE6: Evaporator low temperature protection restoring temperature

TE7: Evaporator high temperature protection, compressor off temperature

TE8: Evaporator high temperature protection, fan off temperature

Protection

8.4.1 The compressor functions protection with a delay of three minutes.

8.4.2 Sensor protection at open circuit and breaking disconnection

8.4.3 Temperature Fuse break protection

8.4.4 Fan Speed is out of control. When Indoor Fan Speed is too high(higher than High

Fan+300RPM)or too low(lower than 400RPM), the unit stops and LED displays failure

information and can’t returns to normal operation automatically.

8.4.5 Cross Zero signal error warning. If there is no Cross Zero signals in 4 minutes, the unit stops

and LED displays failure information and can’t returns to normal operation automatically.

Compressor On, the unit stops and LED displays failure information and can’t returns to

normal operation automatically.

Low room temperature protection:

When room temperature decreases to below 10 ℃ , compressor and outdoor fan will

stop(indoor fan is Breeze). Dehumidifying operation will be resumed when room temperature

restores to over 13℃.

8.7.4

At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same

as that of cooling mode.

8.7.5

At dehumidifying mode, the action of fans of indoor is the same as that of air-only mode.

8.8

Heating mode

8.8.1

Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 4-way

valve must delay 2 minutes compared with compressor if the compressor changed into

non-heating mode or turned off. 4-way valve doesn't delay in dehumidifying mode.

8.8.2

Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode,

except for the defrosting mode or the end of defrost.

8.8.3

Action of compressor and outdoor fan motor at heating mode: compressor must run for 7

minutes after starting and then judge temperature. Meanwhile other protections are still valid.

Defrosting operation (Available for heating only).

8.9.1

Defrosting condition: Defrosting starts when either of the following ①&②:

① A and B are satisfied:

A: The compressor keeps running for 40 minutes or more.

B: The temperature difference of evaporator and room temperature meets one of the

following:

Meet only if it is Breeze

② Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor

fan with the compressor still running. Add up to 90 minutes.

8.9.2 Defrosting time

If the temp. difference condition ① is satisfied for less than 40 minutes, this can be regarded

as severe frosting. The defrosting time is 10 minutes.

If the temp. difference condition ② is satisfied for more than 40 minutes, the defrosting time is

6 minutes.

If the temp. difference condition ① is satisfied out of 40 minutes, generally the defrosting time

is 6 minutes, after three continuous 6-minute defrost, the fourth should be 10 minutes defrost.

The circulation is as following:

→6-minute defrost → 6-minute defrost→6-minute defrost→10-minute defrost→

8.9.3 Ending condition of defrosting

If one of following conditions is satisfied, end the defrost and turn into heating mode:

A. The defrost time has reached to 6 or 10 minutes.

B. The compressor current has reached to I

8.9.4 Defrosting Actions:

8.9.7 Turn into heating mode, turn off the heating mode in 7 minutes.

8.10

Automatic operation mode

8.10.1

The air conditioner automatically selects one of the following operation modes: cooling,

heating or fan only according to the temp. difference between room temp. (TA) and set temp.

(TS).

8.10.2

The indoor fan blows automatically in corresponding selected mode.

8.10.3

The motion of indoor fan’s blade should accord with the selected operation mode.

8.10.4

One mode should be carried out for at least 15 minutes once selected. If the compressor

cannot start for 15 minutes, reselect the operation mode according to the room temp. and set

temp., or reselect when the set temp. varies.

8.11

Forced cooling function

8.11.1

Select forced cooling function with the forced cooling button or the switch.

8.11.2

The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan

mode is set as low, the A/C operates at the DRY mode with a set temp. of 24℃.

8.11.3

All protections of remote control cooling are available at forced cooling operation.

8.12

Forced Auto function

Select forced auto function with the forced auto button or the switch.

In forced auto status the A/C operates at remote control mode with a set temp. of 24℃.

Economic Running

8.14.1

The economic running function is available at cooling, heating or auto mode.

8.14.2

Cooling:

The set temperature rise 1℃ per hour. Two hours later, the set temperature will maintain as

a constant and the fan speed is kept at low speed.

8.14.3

Heating:

The set temperature decrease 1℃ per hour. Two hours later, the set temperature will

maintain as a constant and the air circulation is kept at low speed (Cold air proof function

takes precedence over all).

8.14.4

Auto:

The economic running function operates in accordance with selected running mode by auto

mode.

8.15

Auto restart function

In case of a sudden power failure, this function automatically sets the unit to previous settings

before the power failure when power returns.
