Energy efficiency and quiet operation
Main Features
5
Nighttime quiet operation function
Set on the outdoor PCB. Time of maximum
temperature is memorised. The low
operating mode will initiate 8 hours
*1
after the
peak temperature in the daytime, and normal
operation will resume 10 hours
*2
after that.
The operation sound level for the night mode
can be selected from 55 dB(A) (Step 1),
50 dB(A) (Step 2) and 45 dB(A) (Step 3).
Automatic mode
Operation sound level selectable from 3 steps for the night mode
Mode 1.

Mode 1.
Starting time and ending time can be input.
(An external control adaptor for outdoor unit,
DTA104A53/61/62, and a locally obtained
timer are necessary.)
Manual mode
Mode 2.
Combinations of modes 1 and 2 can be used
depending on your needs.
Combined mode
Mode 3.
*1. Initial setting. Can be selected from 6, 8 and 10 hours.
*2. Initial setting. Can be selected from 8, 9 and 10 hours.
High COPs
It has become essential for air conditioning manufacturers to develop systems that provide high
energy savings. We at Daikin have made great efforts in this field, and the VRVIII delivers highly
efficient performance, contributing to high energy savings.
We have reached a high level of
efficiency, thanks to advanced
features such as the heat
exchanger, the grille and the
dual DC fans.
Achieving a high COP
• Cooling operating conditions: Indoor temp. of 27 °C DB, 19.0 °C WB, and outdoor temp. of 35 °C DB.

Outdoor units use Daikin’s unique scroll compressor to realise energy saving performance
and quiet operation.
• This function is available in setting at site.
• The relationship of outdoor temperature (load) and time shown in the
graph is just an example.
The capacity reduction rate differs depending on the operation sound level step selected.
