11. SALIENT FEATURES

12. 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)

13. 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

14. 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
