Cooling
The following drawings explain the principle of fan speed control for cooling.
Heating
The following drawings explain the principle of fan speed control for heating.
On heating mode, the indoor fan speed will be regulated according to the heat exchanger
temperature and the difference between the room temperature and the required target
temperature.
1.5 Dry
Mode
Outline
Program dry operation removes humidity. Since the microcomputer controls the airflow rate, the
FAN setting buttons are inoperable.
Details
The microcomputer automatically sets the airflow rate. The difference between the room
thermister temperature and the set temperature is divided into zones. Then, the unit operates in
an appropriate capacity for each zone to maintain the temperature and humidity at a
comfortable level.Zone B continues to stay for 120 seconds before the unit will turn to
thermostat ON.
