-State of Operation ON/OFF

-Operation Mode/Setting Temp/Selected Airflow Speed

-Sleep Timer Mode/Remaining Time of Sleep Timer (unit of hour)

Forced Operation (Outdoor unit C/O Model)

To operate the appliance by force in case that the remote controller is lost, the forced operation button is on the main unit of the appliance to operate the appliance in the standard conditions.

Press the forced operation button, the forced operation is carried out.

Press the forced operation button once again to stop operation.

The forced operation is carried out in cooling mode with the setting temperature 22°C and the high speed of airflow.

Forced Operation (Outdoor unit H/P Model)

To operate the appliance by force in case that the remote controller is lost, the forced operation selection switch is on the main unit of the appliance to operate the appliance in the standard conditions.

Press the forced operation button, the forced operation is carried out.

Press the forced operation button once again to stop operation.

In the forced operation mode, the indoor fan is operated at low speed for around 15 sec and then the operation condition is set according to the intake air temperature as follows.

24°C Intake Air Temp => Cooling Mode Operation, 22°C, High Speed

21°C Intake Air Temp < 24°C => Dehumidification Operation, 23°C, High Speed

Intake Air Temp < 21°C

=> Heating Mode Operation, 24°C, High Speed

Test Operation Control

To check the condition of the installation when installing the appliance, the appliance is operated at cooling mode, high speed of airflow, compressor-on for 18 min without controlling the room temperature.

After supplying power to the main body, keep pressing the forced operation button for about 3 seconds.

While in test operation, a key can be input by the remote controller.

When a key (operation start/stop, operation mode selection, airflow speed selection, temperature control, Jet Cool) is input by the remote controller, the test operation is canceled and the appliance is operated according to the setting by the remote controller.

Protection of the evaporator pipe from frosting

In the temperrature of the indoor pipe is below 0°C after 7 minutes from starting the compressor, the compres- sor and outdoor fan are stopped, and 3 minutes delay of operating of the compressor, when the temperature of the indoor pipe is over 7°C, the compressor and the outdoor fan are reoperated.

Outdoor fan motor stops when indoor pipe temperature is blow 3°C and restarts at the pipe temperature above 6°C or after 90 seconds, if the pipe temperature does not rise to 6°C, outdoor fan motor runs continuously at even below 3°C.

R410A specifications

Haier R410A is a refrigerant that has gained significant attention in the HVAC industry due to its environmental benefits and efficient performance. As a hydrofluorocarbon (HFC) refrigerant, R410A is designed to replace the older R22 refrigerant, addressing environmental concerns and aligning with global initiatives to phase out ozone-depleting substances.

One of the primary features of Haier R410A is its low environmental impact. R410A has a significantly lower ozone depletion potential (ODP) compared to R22, making it a more environmentally friendly option. Additionally, it has a global warming potential (GWP) that, while still higher than natural refrigerants, is considered acceptable in terms of modern refrigerant usage and regulatory compliance.

The performance characteristics of R410A are another key point of interest. This refrigerant operates at higher pressure levels compared to R22, which allows for improved heat transfer efficiency. This results in enhanced cooling and heating capabilities, enabling HVAC systems designed for R410A to deliver superior performance in various climate conditions. The higher efficiency translates to lower energy consumption, meaning users can enjoy a comfortable indoor climate while keeping energy bills in check.

In terms of technology, Haier has integrated R410A into a range of air conditioning and refrigeration systems, showcasing the refrigerant’s compatibility with modern HVAC designs. Many of Haier’s products feature advanced inverter technology, which optimizes energy use by adjusting the compressor speed according to the cooling demand. This not only improves efficiency but also extends the lifespan of the equipment.

Moreover, Haier R410A systems are often equipped with smart technologies such as Wi-Fi connectivity and intelligent control features. These innovations allow users to monitor and control their HVAC systems remotely, promoting user convenience and energy savings.

Safety is another characteristic of R410A systems. Although R410A is non-toxic and has a very low flammability risk, it requires appropriate handling procedures due to its higher pressure. Haier adheres to rigorous safety standards in the design and manufacturing of its HVAC units, ensuring that end-users can operate their systems with peace of mind.

Overall, Haier R410A refrigerants represent a significant step forward in achieving efficient, environmentally responsible heating and cooling solutions. With their advanced technology, excellent performance, and commitment to safety, Haier's R410A systems have become a preferred choice among consumers looking for reliable HVAC solutions that also consider ecological impact.
