Operation Details

■Off-Timer <=> On-Timer Operation

•When the set time is reached after the on/off time is input by the remote controller, the on/off-timer operation is carried out according to the set time.

■Sleep Timer Operation

•When the sleep time is reached after <1,2,3,4,5,6,7,0(cancel) hr> is input by the remote controller while in appliance operation, the operation of the appliance stops.

•While the appliance is on pause, the sleep timer mode cannot be input.

•While in cooling mode operation, 30 min later since the start of the sleep timer, the setting temperature increases by 1°C After another 30 min elapse, it increases by 1°C again.

•When the sleep timer mode is input while in cooling cycle mode, the airflow speed of the indoor fan is set to the low.

•When the sleep timer mode is input while in heating cycle mode, the airflow speed of the indoor fan is set to the medium.

■Chaos Swing Mode

•By the Chaos Swing key input, the vane automatically operates with the Chaos Swing or they are fixed to the desired direction.

■Chaos Natural Wind Mode

•When the Chaos Natural Wind mode is selected and then operated, the high, medium, or low speed of the air- flow mode is operated for 2~15 sec randomly by the Chaos Simulation.”

■Jet Cool Mode Operation (Outdoor unit C/O Model)

•If the Jet Cool key is input at any operation mode while in appliance operation, the Jet Cool mode operates.

•In the Jet Cool mode, the indoor fan is operated at super-high speed for 30 min at cooling mode operation.

•In the Jet Cool mode operation, the room temperature is controlled to the setting temperature, 18°C

•When the sleep timer mode is input while in the Jet Cool mode operation, the Jet Cool mode has the priority.

•When the Jet Cool key is input, the upper/lower vanes are reset to those of the initial cooling mode and then operated in order that the air outflow could reach further.

■Jet Cool Mode Operation (Outdoor unit H/P Model)

•While in heating mode or Fuzzy operation, the Jet Cool key cannot be input. When it is input while in the other mode operation (cooling, dehumidification, ventilation), the Jet Cool mode is operated.”

•In the Jet Cool mode, the indoor fan is operated at super-high speed for 30 min at cooling mode operation.

•In the Jet Cool mode operation, the room temperature is controlled to the setting temperature, 18°C

•When the sleep timer mode is input while in the Jet Cool mode operation, the Jet Cool mode has the priority.

•When the Jet Cool key is input, the upper/lower vanes are reset to those of the initial cooling mode and then operated in order that the air outflow could reach further.

■Auto Restarting Operation

•When the power is restored after a sudden power failure while in appliance operation, the mode before the power failure is kept on the memory and the appliance automatically operates in the mode on the memory.

•Operation Mode that is kept on the memory

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.
