6. Control functions
6.1. Temperature Parameters
•
Indoor ambient temperature (T
in_amb.
)
•
Evaporator tube temperature (T
in_tube
)
Setting temperature (T
set
)
Note:
The following function manual, the temperature unit is centigrade, if there is Fahrenheit, there will be
T(°F)=T(°Cx1.8+32.
6.2. Basic functions
6.2.1 Cooling mode
1. Temperature can be set in the range of 16 ~ 30°C.
2. The unit will firstly run at high fan speed for 8s and then switch to preset fan speed.
3. When error of outdoor unit occurs or the unit stops for protection, indoor unit will keep its original operating state.
6.2.2 Dehumidifying mode
1. Temperature can be set in the range of 16 ~ 30°C.
2. The unit will firstly run at high fan speed for 8s and then switch to low fan speed.
3. When error of outdoor unit occurs or the unit stops for protection, indoor unit will keep its original operating state.
6.2.3 Fan mode
1. The unit will firstly run at high fan speed for 8s and then switch to preset fan speed.
2. When error of outdoor unit occurs or the unit stops for protection, indoor unit will keep its original operating state.
6.2.4 Heating mode
1. Temperature can be set in the range of 16 ~ 30°C.
2. If compress stops at required temperature point, indoor fan will run by blowing residual heat.
3. If compress under heating mode stops for error, indoor fan will run by blowing residual heat.
4. Function of blowing residual heat:
Indoor fan switching into low speed will stops after 1 min delay.
5. Anti-cold air
After heating compressor runs, indoor fan runs according to the following conditions:
If compressor runs within 90s and T
in_tube
< 35°C, indoor fan won't run. When T
in_tube
≥
35°C or compressor run for 90s
above, indoor fan will run at low speed. After 3 min at low speed or T
in_tube
≥
40°C, indoor fan runs at preset speed. Once
running, indoor fan won't stop. Once at preset fan speed, it won't forcibly return to low speed.
6.2.5 AUTO mode
1) When T
in_amb.
≥
25°C, the unit runs under cooling mode, T
set
= 25°C.
2) When T
in_amb.
≤
18°C, the unit runs under heating mode, T
set
= 18°C. And it runs under fan.
3) When 18°C < T
in_amb.
< 25°C, the unit keeps its original operating state. If first energization, it runs under fan mode.
6.3. Others
6.3.1 Buzzer
The air conditioner will send out Hua alert when it is energized or receives a control command.
6.3.2 Auto Button
When turn off the unit, press this button, the whole unit will run at auto mode, indoor fan motor will run in auto fan speed,
turn on the swing. At unit turns on, press the Auto button that the unit will turns off.
6.3.3 Auto fan speed control
Under Cool, Heat, Fan modes, indoor fan will accord to the ambient temperature select High, Mid, Low three speeds, the
dehumidifying mode auto fan speed is low. The switch of each fan mode should be 3.5mins.
6.3.4 Timer function
The common setting for Timer:
a) Timer on: At unit off, can set up the Timer On function, when Timer On act, the controller will run at original setting
mode, the Timer interval is 0.5hr, setting range is 0.5-24hrs.
