1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas or alkaline gas, are produced.2. If the outdoor unit is to be installed close to the sea shore, direct exposure to the sea breeze should be avoided. If you need to install

the outdoor unit close to the sea shore, contact your local distributor.

Outdoor PCB automatically memorises the time when the peak outdoor temperature appears. It will enable quiet operation mode after 8 h*1, and return to normal mode after it keeps for 9 h*2.

*1 8 h is the initial setting with 6 h or 10 h also available.*2 9 h is the initial setting with 8 h or 10 h also available.

Notes: This function is available in setting at site. The operating sound in quiet operation mode is the actual value

measured by our company. The relationship of outdoor temperature (load) and time shown

above is just an example.

Streamlined air grilleIt promotes the discharge of swirling airflow, further reducing the pressure loss.

Streamlined scroll fanThe sharp edge of each fan blade has a certain curvature, reducing both the vibration and the pressure loss.

How is energy reduced?During cooling, the refrigerant evaporating temperature (Te) is raised to minimise the difference with the condensing temperature.During heating, condensing temperature (Tc) is lowered to minimise the difference to the evaporating temperature. Compressors work less, and this reduces power comsumption.

State-of-the-art energy saving technology for VRV system

Can boost capacity above 100% if needed. The refrigerant temperature can go lower in cooling (higher in heating) than the set minimum (maximum in heating). Gives priority to very fast reaction speed. The refrigerant temperature goes down (or up in heating) fast to keep

the room setpoint stable.

Gives priority to fast reaction speed. The refrigerant temperature goes down (or up in heating) fast to keep

the room setpoint stable.

Gives priority to efficiency. The refrigerant temperature goes down (or up in heating) gradually giving

priority to the efficiency of the system instead of the reaction speed.

Recommended for use in these situations

Basic mode is selected to maintain optimal comfort.VRT is selected to save energy and prevent excessive cooling or heating.

Cooling only regions having differences in daily temperature.

Cooling/heating regions having periods of mild outdoor temperatures.

VRT is particularly effective during the intermediate periods.

Selecting VRT enables operation to be optimised for either energy efficiency or rapid cooling/heating.

Customise your VRV system for optimal annual efficiencyThe new VRV IV system now features VRT technology.VRT automatically adjusts refrigerant temperature to individual building and climate requirement, thus further improving annual energy efficiency and maintaining comfort.With this excellent technology, running costs are reduced.

Required capacity changes as air conditioning load changes according to outdoor temperature.

Energy efficiency is improved without sacrificing comfort.

Automatic control adjusts evaporating temperature to heat load change.

In case of fixed evaporating temperature, excessive cooling, thermo on-off loss, and other inefficiencies occur.

Outdoor unit sequencing technology

Daikin VRV IV system incorporates a simplified and efficient test operation function, not only greatly accelerating the installation process, but effectively improving the field setting quality as well.

Efficient automatic test operation Automatic sequencing operation

Automatically checks the wirings between outdoor units and indoor units to confirm whether there is a defective wiring.

Confirms and corrects the actual piping length.

Automatically check whether the stop valve in each outdoor unit is in normal status to ensure the smooth operation of air conditioning system.

Automatic check

During start-up, Daikin VRV IV unit sequencing operation will be automatically enabled toensure balanced operation of each outdoor unit to improve longevity of equipment and stable operation.

Double backup operation functions responding resiliently to various unexpected situations

Stage 1 Stage 2 Stage 3

Priority: Priority: Priority:

Daikin VRV IV system boasts double backup operation functions, which can secure the use of air conditioners in this area to the greatest extent by emergently enabling double backup operation functions even if failure occurs in a set of air conditioning equipment.In the event of a failure, emergency operation can be conveniently enabled to allow the remaining system to operate in a limited fashion.

Double backup operation functionsSimplified commissioning and after-sales service

VRV IV system utilises 7-segment luminous digital tubes to display system operation information, enabling the operational state to be visually displayed whilst facilitating simplified commissioning and after-sales service.

Function of information display by luminous digital tube

The VRV configurator is an advanced software solution that allows for easy system configuration and commissioning.

less time is required on the roof configuring the outdoor unit.

multiple systems at different sites can be managed in exactly the same way, thus offering simplified commissioning for key accounts.

Initial settings on the outdoor unit can be easily retrieved.

Energy efficiency has been improved thanks to the adoption of a new heat exchanger with smaller tubes, DC fan motor and DC drain pump motor.

The sensor detects human presence and adjusts the airflow direction automatically to prevent drafts.Energy saving control can be performed when no people are detected.

Individual airflow direction example case

When there are no people in a room, the set temperature is shifted automatically.

If people do not return, the air conditioner will raise the temperature 1C every 30 minutes and then operate at 30C.

Example: Cooling setpoint: 26C Shift temperature: 1.0C

Shift time: 30 min. Limit cooling temperature: 30C

Shift temperature and time can be selected from 0.5 to 4C in 0.5C increments and 15, 30, 45, 60, 90 or 120 minutes respectively with remote controller.

When there are no people in a room, the system stops automatically.Absent stop time can be selected from 1 to 24 hrs in 1 hr increments with remote controller.

New airflow block function prevents uncomfortable drafts by reducing air velocity. It can be set using the BRC1E62 remote controller. There is no need for sealing material of air discharge outlet (option).This function only works when all-round flow is used. It cannot be used when sealing material is used in the air discharge outlet (option).

Also can support such this case

The airflow block function is useful when rearranging the room layout.

Floor temperature is detected and over cooling prevented.

Energy savingsThe temperature near the person is automatically calculated by detecting the temperature of the floor. Energy is saved, because the area around the feet does not get too cold.Comfortable airflowAirflow rate automatically increases during hot or cold periods (when there is a large difference with set temperature), and operation is rapidly performed for cooling or heating.When the difference with set temperature becomes small, drafts are prevented by automatically reducing airflow rate, and raising the flap to a horizontal position during cooling operation.

30C near ceiling30C near ceiling

20C near floor20C near floor

Room temperature is

detected as 30C.

Room temperature is calculated as 27C in the area which

is in the vicinity of the person.

30C near ceiling30C near ceiling

24C near floor24C near floor

Automatic control using the temperature near the person as the room temperature.

The floor temperature, which is lower than near the ceiling, is detected.

Area around feet gets too cold because air conditioner continues until the temperature near the ceiling reaches the set temperature.

Note: Whatever the discharge direction, the same type of panel is used. If installing for other than all-round flow, an air discharge outlet sealing material (option) must be used to close each unused outlet.
