SALIENT FEATURES

Daikin VRV IV Space mounted technology (SMT) packaging technology• Protects your computer board from the adverse effect of sandy and humid weather VRT Technology• Energy efficient- 4 modes available: Powerful mode, Quick mode, Mild mode & Eco

mode Refrigerant PCB cooling• More efficient cooling without affected by the ambient temperature• Ensure stability of PCB temperature Neodymium magnet based compressors• 50% more neodymium magnet in scroll compressors Ceiling mounted round flow cassette with sensors• Presence of people and floor temperature can be detected to provide comfort and

energy savings Individual airflow direction control• Air flow direction can be individually adjusted for each air discharge outlet (Position 0 to

4, Swing, No individual setting are selectable)

Daikin VRV IV Auto airflow rate• Airflow rate automatically adjusted depending upon the difference b/w

room temperature & set temperature. Set point range• Saves energy by limiting the min. and max. set temperature Set point auto reset• If the set temperature is changed, it returns to preset temperature

after preset time. Period selection ranges from 30 min to 120 min Setback• Maintain the room temperature in a specific range during unoccupied

time by temporarily starting the AC that was turned OFF- Cooling: 33-37°C with recovery differential -2 to -8°C, Heating: 10-15°C with recovery differential 2 to 8°C

Daikin VRV IV Sensing sensor low mode• When there are no people in a room, set temperature is shifted

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

Sensing sensor stop mode• 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)

Airflow block function• Enhances comfort- Airflow block function prevents uncomfortable

drafts by reducing air velocity by approx. 0.3 m/s

LG Multi V IV • HiPOR™ (High pressure oil return)• Variable heat exchanger circuit• Vapor injection• Active refrigerant control• Continuous heating operation in defrost• Cannon fan: high air volume, low noise level and high efficiency• New refrigerant quantity decision feature• FDD (Fault detection & diagnosis)• Smartphone monitoring & control • Auto refrigerant collection• Auto compressor oil management

Hitachi Set Free• DC motor with reduced noise & higher efficiency• Motion sensor• Anti-bacterial condensate drain• Independent louver control• Ferrite magnet based DC motor• Econofresh kit optional enthalpic and CO2 sensor• Centralized controller• Capacity adjustment using DIP switch• Adaptability to high ceiling

Chigo CMV• Brushless DC motor• 180° sine wave control• Cross flow fins• Super cooling flow path design• 2 in 1 refrigerant path design• Anti vibration fan blade• Streamline duct design• Anti snow function• Circuit silencer• Emergency stop operation• Adjustable outdoor fan ESP• Oil control technology
