Operation

2)Fuzzy Operation for Dehumidification

According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C(0.9°F) or more below the setting temp, the compressor is turned off. When 0.5°C(0.9°F) or more above the setting temp, the compressor is turned on.

Compressor ON Temp

Setting Temp + 0.5°C(0.9°F)

Compressor OFF Temp

Setting Temp+0.5°C(0.9°F)

At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air temp at that time.

26°C(78.8°F)

Intake Air Temp

25°C(77°F)

24°C(75.2°F)

Intake Air Temp<26°C(78.8°F)

Intake Air Temp+1°C(1.8°F)

22°C(71.6°F)

Intake Air Temp<24°C(75.2°F)

Intake Air Temp+0.5°C(0.9°F)

18°C(64.4°F)

Intake Air Temp<22°C(71.6°F)

Intake Air Temp

Intake Air Temp<18°C(64.4°F)

18°C(64.4°F)

When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature automatically according to the Fuzzy rule.

While in Fuzzy operation, the airflow speed of the indoor fan repeats the low airflow speed or pause as in dehumidification operation.

3)Fuzzy Operation for Heating

According to the setting temperature selected by Fuzzy rule, when the intake air temp is 3°C(37.4°F) or more above the setting temp, the compressor is turned off. When below the setting temp, the compressor is turned on.

Compressor ON Temp

Setting Temp

Compressor OFF Temp

Setting Temp + 3°C(5.4°F)

At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air temp at that time.

20°C(68°F)Intake Air Temp

Intake Air Temp + 0.5°C(0.9°F)

Intake Air Temp<20°C(68°F)

20°C(68°F)

When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature automatically according to the Fuzzy rule.

While in Fuzzy operation, the airflow speed of the indoor fan is set to the high or the medium according to the intake air temperature and the setting temperature.

Airflow Speed Selection

The airflow speed of the indoor fan is set to high, medium, low, or power (auto) by the input of the airflow speed selection key on the remote control.

On-Timer Operation

When the set time is reached after the time is input by the remote control, the appliance starts to operate.

The timer LED is on when the on-timer is input. It is off when the time set by the timer is reached.

If the appliance is operating at the time set by the timer, the operation continues.

While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temperature.

Off-Timer Operation

When the set time is reached after the time is input by the remote control, the appliance stops operating.

The timer LED is on when the off-timer is input. It is off when the time set by the timer is reached.

This capability offers the convenience of adjusting settings from anywhere, ensuring that your space is always at the desired temperature when you arrive home or the office. The app can provide insights into energy consumption, allowing users to make informed decisions about their heating and cooling usage.

The DMH24DB-1 and DMC24DB-1 models also boast efficient filtration systems that help improve indoor air quality. The filters are designed to capture dust, pollen, and other allergens, contributing to a healthier living or working environment. This is particularly important for individuals with allergies or respiratory issues.

With a variety of cooling and heating modes, these units can cater to different user preferences and seasonal demands. Features like turbo mode are designed to quickly bring a space to the desired temperature, while the eco-friendly refrigerant helps reduce environmental impact.

In summary, the Heat Controller DMH24DB-1 and DMC24DB-1 units are high-performance air conditioning systems equipped with advanced technologies and practical features, making them an excellent choice for anyone seeking efficient and reliable climate control solutions. Their energy efficiency, enhanced air quality, and smart technology integration position them as leaders in the market.
