6.3 Function Introduction
Ⅰ
Basic functions:
一、
Cooling mode
1. Working condition and process for cooling
：
a.When Tinner amb. ≥Tpreset, the unit operates under cooling mode. Meanwhile, the fan and the compressor operate, and the fan oper
-
ates at set fan speed;
b. When Tinner amb. ≤Tpreset-2
℃
, the compressor stops operation, and the fan operates at set fan speed;
c. When Tpreset-2
℃＜
Tinner amb.
＜
Tpreset, the unit keeps previous operation status.
d. When turning off the unit, the compressor stops operation. The fan will stop operation after operating at low fan speed for another 30s.
2. Under cooling mode, the temperature setting range is 1
6℃～
3
0℃
. When compressor stops operation due to malfunction, the fan and
the swing fan operate at original status.
二、
Drying mode
1
、
Working condition and process for drying:
a. When Tinner amb.
＞
Tpreset, the unit operates at drying mode. Meanwhile, the fan and the compressor operate, and the fan is de-
faulted to operate at low fan speed;
b. When Tpreset-2
℃
≤Tinner amb.≤Tpreset, the unit keeps the original operation status;
c. When Tinner amb.
＜
Tpreset-2
℃
, compressor stops operation, and the fan is defaulted to operate at low fan speed.
d. When turning off the unit, the compressor stops operation. The fan will stop operation after operating at low fan speed for another 30s.

、
In this mode, the temperature setting range is 16
℃～
30
℃
.
三、
Auto mode
Working condition and process for auto operation
a. When Tinner amb.≥26
℃
, the unit operates at cooling mode and Tpreset=25
℃
;
b. When T inner amb.≤ 22
℃
, the unit operate at fan mode and Tpreset=2
0℃
;
c
.
When 22
℃＜
Tinner amb.
＜
26
℃
, the unit keeps the original operation status;If it’s the first time to enter into auto mode, the unit will
operate at fan mode.
四、
Fan mode
Under the fan mode, compressor stops operation and the fan operates at set fan speed. Temperature can’t be set by buttons on the con-
trol panel, while it can be set by remote controller.

Buttons’ function
1. ON/OFF:
It used to turn on or turn off the unit.
2. Mode:
It used to switch among cooling mode, drying mode and fan mode.
3. Fan speed
:
It used to set high, medium, low or auto fan speed. The corresponding LED indicator is on (under drying mode, this button can’t be ad-
justed. The fan speed is the low speed).
4.+/- button:
4.1 The temperature setting range is 0~24 hours. The timer can be set in 0.5 hour increments between 1 and 10 hours; or in 1 hour incre-
ments for 10 hours above.
4.2 Under temperature setting range, each push on +/- button will increase or decrease 1
℃
.
5. Swing
:
Press this button to turn on swing function; press this button again to cancel swing function.
6. Timer function
6.1 Timer ON: Timer ON can be set under OFF status, and then Timer ON setting range is 0.5
～
24
hours. When the set time is
reached, the system will operate at the preset mode.
6.2 Timer OFF: Timer OFF can be set under ON status, and then Timer OFF setting range is 0.5
～
24 hours. When the set time is
reached, the system will stop operation.
7. The dual-8 nixie tube is defaulted to display
℃
. The displays can switch among
℃
and
℉
. Press “+”and“-”buttons simultaneously for
3s to switch them.
8. FILTER
When the fan has operated for 250hour in all, the filter indicator will be on to remind user to clean the filter. When the filter indicator is on,
press filter button to clear the accumulated operation time and the filter indicator will be off.
9. Sleeping mode
；
9.1
When the initial temperature is set at 16
～
23
℃
, after turning on the sleeping function, the temperature will increase by 1
℃
every
two hours. When the temperature is increased by 3
℃
, the temperature will not change any more. When the unit has operated for 7
hours, the temperature will decreased by 1
℃
. After that, the unit will operate at this time all the time.
9.2
When the initial temperature is set at 24
～
27
℃
, after turning on the sleeping function, the temperature will increase by 1
℃
every
