Defrost ControlHeating, Fuzzy Operation | Heat Controller DMC24DB-1

Operation

27°C(80.6°F), it operates with Super-Low(while in sleep mode, with the medium airflow speed).

•While compressor off, the indoor fan is off when the indoor pipe temp is below 33°C(91.4°F), when above 35°C(95°F) , it operates with the low airflow speed.

•While in defrost control, the indoor is outdoor fans are turned off.

■Defrost Control(Heating)

•Defrost operation is controlled by timer and sensing temperature of outdoor pipe.

•The first defrost starts only when the outdoor pipe temperature falls below -6°C(21.2°F) after 35 minutes passed from starting of heating operation and more than 4 minutes operation of compressor.

•Defrost ends after 12 minutes passed from starting of defrost operation when the outdoor pipe temperature rises over 15°C(59°F) even before 12 minutes.

•The second defrost starts only when the outdoor pipe temperature falls below -6°C(21.2°F) after 35 minutes passed from ending of the first defrost and more than 4 minutes operation of compressor.

■Fuzzy Operation

•When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since the operation off, the operation mode is selected.

•When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only the indoor fan is operated for 15 seconds. Then an operation mode is selected according to the intake air temp at that moment as follows.

24°C(75.2°F) ≤	Intake Air Temp	➲ Fuzzy Operation for Cooling
21°C(69.8°F) ≤	Intake Air Temp<24°C(75.2°F)	➲ Fuzzy Operation for Dehumidification
Intake Air Temp<21°C(69.8°F)		➲ Fuzzy Operation for Heating

•If any of the operation modes among cooling / dehumidification / heating mode operations is carried out for 10 sec or longer before Fuzzy operation, the mode before Fuzzy operation is operated.

1)Fuzzy Operation for Cooling

•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 is automatically selected according to the temper- ature.

By operating at variable speeds instead of a fixed setting, the inverter provides a more consistent temperature, reduces wear and tear on components, and minimizes energy consumption, which can translate to lower electricity bills.

Both models offer a sleek and modern design, making them not only functional but also aesthetically pleasing. The indoor units are designed for easy placement in various environments and can blend seamlessly with any decor. In addition, they are relatively quiet during operation, with low noise levels that enhance indoor comfort without disturbing daily activities.

Another notable feature is the integrated smart control system that allows users to operate the units via a smartphone or tablet. 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.
