◆Indoor set temperature (Tpreset)
◆Indoor ambient temperature (Tamb.)
◆Inner tube temperature of indoor evaporator (Ttube)
2. Introduction of basic mode function
Once the compressor is energized, there should be a minimum interval of 3 mins between two start-ups.
If the unit is with memory function and is off before power failure, the compressor can be restarted without an interval of 3 mins; if the
unit is on before power failure, the compressor will be restarted with an interval of 3 mins.
Once compressor is started, it won’t stop within 6 mins according to the change of room temp.
(1) Auto mode
①
Operation condition and process
Under auto mode, the system will automatically select operation mode (cooling, dry, heating and fan) according to indoor ambient
temperature.
◆
When Tamb.＞26℃, the system operates under cooling mode; Ex-factory set temperature is 26℃.
◆
When 20℃≤Tamb.≤26℃, the system operates under drying mode; Ex-factory set temperature is 24℃.
◆
Heat pump unit: when Tamb.＜20℃, the system operates under heating mode; Ex-factory set temperature is 20℃.
◆
Cooling only unit: when Tamb.＜20℃, the system operates under fan mode; Ex-factory set temperature is 20℃.

Operation condition and process
◆
When Tamb.≥Tset+1℃, the system operates under cooling mode. In this case, the compressor and the ODU fan motor operate,
and the IDU fan motor operates at set speed.
◆
When Tset-1℃＜Tamb.＜Tset+1℃, the system will maintain its previous operation status.
◆
When Tamb.≤Tset-1℃, the compressor and the ODU fan motor stop, while the IDU fan motor operates at set speed.
In cooling mode, the 4-way valve is de-energized (4-way valve is not available for cooling only unit). Temperature setting range is

When Tamb.≥Tpreset+1℃, the compressor and the ODU fan motor stop. The 4-way valve is energized all the time. The IDU fan
motor will blow residual heat after operating at set speed for a period of time consecutively to make sure the inner temperature of air
conditioner won’t be too high.
In heating mode, 4-way valve is energized. Temperature setting range is 16～30℃.
②
Defrosting condition and process
In order to ensure heating effect, the unit will proceed defrosting automatically according to the frost situation of outdoor unit. Dual-8
