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 oper­ates 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℃～30℃

. 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 de­faulted 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.
2、 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=20℃;

c． When 22℃＜Tinner amb.＜ 26℃, the unit keeps the original operation status;

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 con­trol panel, while it can be set by remote controller.
