2. In heating mode:
2.1 When the initial set temperature is 16°C, the unit will keep on running at this temperature;
2.2 When the initial set temperature is 17~20°C, the temperature will decrease 1°C by every hour after sleep function is set; the
temperature will not change after decreasing 1°C;
2.3 When the initial set temperature is 21~27°C, the temperature will decrease 1°C by every hour after sleep function is set; the
temperature will not change after decreasing 2°C;
2.4 When the initial set temperature is 28~30°C, the temperature will decrease 1°C by every hour after sleep function is set; the
temperature will not change after decreasing 3°C;
Relationship between set temperature and running time:

(6) Indoor Fan Control
The Indoor Fan can be set as HIGH, MED, LOW by remote control, and the Indoor Fan will be respectively run at high, medium, low
speed. It will also be set as AUTO, and the Indoor Fan is as the followings at the automatic wind speed.
①
Cooling mode: in auto cooling mode or normal cooling mode, the auto fan speed will run at below mode:
a. When Tamb.≥2°C, the indoor fan will run at high speed;
b. When Tpreset<Tamb.<2°C, the indoor fan will run at middle speed;
c. Tamb.≤Tpreset, the indoor fan will run at low speed;
Switches between high speed and middle speed, middle speed and low speed, high speed and low speed, running time of 3.5 minutes
must be ensured.
②
Heating mode: in auto heating mode or normal heating mode, the auto fan speed will run at below mode:
a. When Tamb.≤1°C, the indoor fan will run at high speed;
b. When 1°C<Tamb.<3°C, the indoor fan will run at middle speed;
c. Tamb. ≥3°C, the indoor fan will run at low speed;
Switches between high speed and middle speed, middle speed and low speed, high speed and low speed, running time of 3.5 minutes
must be ensured.
Fan mode is the same as cooling mode.
