2.3 Dehumidifying operation
1.Under dehumidifying mode , the water drainage pump will always open , with temperature controlled in
the range of 16
℃
- 32
℃
and other actions as follows:
(1) When TA ≥ TS+2 ℃ , the cooling electric valve will open and the indoor fan will operate at set speed;
(2) When TS ≤ TA < TS+2
℃
, the cooling valve will open and the indoor fan will be turned on for 10
minutes and off for 6 minutes and run at low air speed;
(3)When TA
＜
TS, the cooling electric valve will close and the indoor fan will stop operating 10 seconds
after the valve is closed
The low speed operation of the indoor fan will be activated 40 seconds after 5 minutes, if TA - TS≤-2
℃
the indoor fan will remain stopped for 5minutes before reactivate low speed operation for 40 seconds;
otherwise, the related cooling operation will be controlled according to indoor temperature

2.Automatic air speed control:
When TA - TS≥2
℃
, the cooling electric valve will open and the fan will operate at high speed;
When TS ≤ TA < TS+2
℃
, the indoor fan will be turned on for 10 minutes and off for 6 minutes and run
at low air speed;
When TA ＜ TS, the cooling electric valve will close and the indoor fan will stop operating 10 seconds
after the valve is closed.
The low speed operation of the indoor fan will be activated 40 seconds after 5 minutes, if TA - TS≤-2

set using the remote control. There are timing and power fail memory functions in this mode .
2.5 Heating operation
The temperature setting is determined by the remote control with temperature controlled in the range of
16 ℃ -32 ℃ .The temperature setting can be adjusted using the “TEMP” and “TEMPERATURE-”
buttons. Depressing “Speed Selection” button allows selecting between “AUTO”, “High Speed”, “Middle
Speed” and “Low Speed” modes; other actions are as follows:
1.When TA-TS≤-2
℃
, the cooling electric valve will open and the indoor fan will operate at set speed ,
with the AUKSiliary electric heater turned on;
2.When TA-TS≤-1
℃
, the cooling electric valve will open and the indoor fan will operate at set speed ,
with AUKSiliary electric heater turned on when using single electric heater;
3.When TA=TS, the cooling electric valve will remain previous status, with AUKSiliary electric
heater turned off;
4.When TA-TS≥1 ℃ , the cooling electric valve will close and the indoor fan will operate at low speed ,
