NOTE
●
Intermittent ventilation occurs by switching the indoor fan speed between low speed to STOP.
●
Dry operation does not occur when the room temperature is under 15 °C which is the monitor zone.
●
When the compressor stops, the indoor fan stops as well.
4) DRY OPERATION (DEHUMIDIFICATION) HEAT PUMP MODEL
●
Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low
level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of
turning ON an OFF automatically as shown in the chart below according to the room temperature.
5) AUTOMATIC SWITCHING BETWEEN COOLING AND HEATING (HEAT PUMP MODEL)
●
When auto mode is selected, the microprocessor calculates the difference between the set temperature
and the room temperature, and automatically switches to cooling or heating mode to maintain the desired
temperature.
●
This means that if the room temperature is higher than or equal to the set temperature, cooling operation
begins. If the room temperature is lower than the set temperature, heating operation begins.
