Based on the heat exchange temperature to control the indoor fan as the above shown.
1. When the heat exchange temperature rise, to distinguish the fan speed based on the heat exchange
temperature:
The heat exchange temperature is less than 35.2 , the speed of fan motor isć weak (for the first power
on, when the system operating in heat mode or OFF the defrost mode, and when the heat exchange
temperature is less than 25.2 , the fan mć otor will OFF; if the temperature is between 25.2 andć
35.2 , the fan motor willć be weak speed operating);
The fan motor operating with low speed when heat exchange temperature is between 35.2 andć
37ć˗
The heat exchange temperature is more than 37 , fać n motor operating by the set speed.
2. When drop of the heat exchange temperature, to distinguish the fan speed based on the heat
exchange temperature:
The fan motor operating with low speed when heat exchange temperature is between 35.2 andć
25.2 ;ć
The fan motor always operates with little-low speed when heat exchange temperature is less than
25.2 . (for the first power on, when the system operating in heat mode orć stopping the defrost mode,
and when the heat exchange temperature is between 25.2 and 16ć , the fan motor will operatingć
with weak speed; when the temperature is drop down to under16 , the fan motor will be stopped.ć ˅
3. During the heat exchange temperature is risingˈfan speed is in the weak and low speed status, if
the heat exchange temperature don’t return to previous value after 4 minutes, the fan speed will rise
and continuously operating by the set temperature for 4 minutes, the system will adjustment the fan
speed based on the heat exchange temperature;
4. When the heat exchange temperature is dropping down, the fan speed will go up to the set speed
if the fan motor operate continuously by the low speed for more than 4 minutes.
