Service Manual
1. Press the back side of remote controller on the spot marked with , and then
push out the cover of battery box along the arrow direction.
2. Replace two No.7 (AAA 1.5V) dry batteries and make sure the positions of + and --
polar are correct.
3. Reinstall the cover of battery box.
Note:
During operation, point the signal sender of the remote controller at the receiving
window of the indoor unit;
The distance between signal sender and receiving window should be within 8m.
There should be no obstacle between them.
Signal may be interfered easily in the room where there is fl uorescent lamp
or wireless telephone; Remote controller should be close to indoor unit during
operation.
Replace new batteries of the same model when replacement is required.
If you don't use remote controller for a long time, please take out the batteries.
If the display on remote controller is fuzzy or if there's no display, please replace

6.2 Brief Description of Modes and Functions
1. Temperature Parameters
◆Indoor preset temperature (Tpreset)
◆Indoor ambient temperature (Tamb.)
2. Basic Functions
Once energized, in no case should the compressor be restarted within less than 3 minutes. In the situation that memory function
is available, for the rst energization, if the compressor is at stop before de-energization, the compressor will be started without a
3-minute lag; if the compressor is in operation before de-energization, the compressor will be started with a 3-minute lag; and once
started, the compressor will not be stopped within 6 minutes regardless of changes in room temperature;
(1) Cooling Mode
①Working conditions and process of cooling
Cooling conditions and process(09k)
a. When Tamb.≥Tpreset the unit starts cooling. In this case, the IDU fan motor, ODU fan motor and compressor run, and the IDU fan
motor runs at set speed;
b. When Tamb.=Tpreset-3℃, the compressor continuously operates below the frequency of 15Hz (not including 15Hz) for 15mins. If
Tamb.=Tset-3℃ still keeps the same, the compressor stops operation;
c. When Tamb.≤Tpreset-4℃, the compressor stops operation; ODU fan motor stops operation with a delay of 30s and IDU fan motor
operates at set speed;
d. When Tpreset-2℃＜ Tamb. ＜Tset, the unit will maintain its previous running status.
Cooling conditions and process(12k)
a.When Tamb.+Tindoor supplementary≥Tpreset, the unit starts cooling. In this case, the IDU fan motor, ODU fan motor and
compressor run, and the IDU fan motor runs at set speed;
b. When Tamb.+Tindoor supplementary≤Tpreset-2℃, the compressor stops operation; ODU fan motor stops operation with a delay
of 30s and IDU fan motor operates at set speed;
c.When Tpreset-2℃＜ Tindoor amb.+Tindoor supplementary ＜Tpreset, the unit will maintain its previous running status.
Under this mode, the four-way valve will be de-energized and temperature can be set within a range from 16 to 30oC.
If the compressor is shut down for some reason, the indoor fan and the swing device will operate at original state.
②Protection
◆Antifreeze protection
Under cooling and dehumidifying mode, 6 minutes after the compressor is started:
If T evap≤2oC, the compressor will operate at reduced frequency.
If T evap≤-1oCis detected for durative 3 minutes, the compressor will stop, and after 30 seconds, the outdoor fan will stop; and under
cooling mode, the indoor fan and the swing motor will remain at the original state.
If T evap. ≥10oCand the compressor has remained at OFF for at least 3 minutes, the compressor will resume its original operation
state.
◆Total current up and frequency down protection
If Itotal≤6, frequency rise will be allowed; if Itotal≥7, frequency rise will not be allowed; if Itotal≥8, the compressor will run at reduced
frequency; and if Itotal≥9, the compressor will stop and the outdoor fan will stop with a time lag of 30s.
(2) Dehumidifying Mode
①Working conditions and process of dehumidifying
If Tamb>Tpreset, the unit will enter cooling and dehumidifying mode, in which case the compressor and the outdoor fan will operate
and the indoor fan will run at low speed.
If Tpreset -2oC≤Tamb≤Tpreset, the compressor remains at its original operation state.
If Tamb.< Tpreset -2oC, the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will operate at
low speed.
②Protection
Protection is the same as that under the cooling mode.
(3) Heating Mode
