2. Basic Functions of System
After the unit is energized, the interval of start-up time for compressor is no less than 3min under any conditions; when the
compressor is started, the unit is off without the temperature change in 6min.
2.1 Cool Mode
2.1.1 Working conditions and process of cooling
a) When T

o
C (2

runs under preset fan speed.
b) When T

2.2 DRY Mode
2.2.1 Working conditions and process of dry
Under this mode, the unit will not display setting temperature and ambient temperature; the fan motor runs under low fan speed; the
compressor, fan motor and kick motor continue to run.
2.3 FAN Mode
 Under this mode, the unit will not display setting temperature and ambient temperature; the fan motor runs under setting fan speed;
the compressor, fan motor and kick motor stop to run.
 Under this mode, the centigrade temperature setting range is 16
o
C -30
o

3. Other Functions
3.1 Buzzer
When the controller is energized, receiving a signal from remote controller or button, the buzzer will give out a beep.
3.2 Sleep
a) Under cooling mode, after 1h of setting sleep process, Tpreset increases 2
o
F(1
o
C); 2h later, Tpreset increases 4
o
F(2
o
C). After 2h,
the setting temperature never increases, but the upper limit of increased setting temperature is 86
o
F(30
o
C)
b) Under heating mode, after 1h of setting sleep process, Tpreset decreases 2
o
F(1
o
C); 2h later, Tpreset decreases 4
o
F(2
o
C). After 2h,
the setting temperature never decreases, but the upper limit of decreased setting temperature is 61
o
F(16
o
C)
c) There is no sleep function under fan and dry mode.
d) When set sleep function, shift mode will cancel sleep function.
e) The setting temperature display is the same with remote controller; it is not influenced by the setting temperature increases/
decreases.
