Note For Multi System - Daikin FTKS50GVMG Operation Manual

Note for Multi System

〈〈
What is a "Multi System"?
This system has one outdoor unit connected to
multiple indoor units.
■ When the simultaneous
operational capacity is
exceeded
If the simultaneous operational capacity is exceeded
for outdoor unit capacity, the indoor unit enters
Standby Mode, and the operation light flashed; this is
not a malfunction.
<Example>
When the units in rooms A, B, and C are being used, and the D is used, causing an overload:
The room (from A to D) which is closest to the set temperature will go into standby mode.
The room in standby mode will resume operation once operation in the other rooms is
stopped.
■ NIGHT QUIET Mode
NIGHT QUIET Mode requires initial programming during installation. Please consult your retailer
or dealer for assistance.
NIGHT QUIET Mode reduces the operation noise of the outdoor unit during the night time hours to
prevent annoyance to neighbors.
• The NIGHT QUIET Mode is activated when the temperature drops 5°C or more below the
highest temperature recorded that day. Therefore, when the temperature difference is less than
5°C, this function will not be activated.
• NIGHT QUIET Mode reduces slightly the cooling efficiency of the unit.
■ OUTDOOR UNIT QUIET Operation
1. With the Priority Room Setting present but inactive or not present.
When using the OUTDOOR UNIT QUIET operation feature with the Multi system, set all
indoor units to OUTDOOR UNIT QUIET operation using their remote controllers.
When clearing OUTDOOR UNIT QUIET operation, clear one of the operating indoor units
using their remote controller.
However OUTDOOR UNIT QUIET operation display remains on the remote controller for other
rooms.
We recommend you release all rooms using their remote controllers.
2. With the Priority Room Setting active.
See "Priority Room Setting" on the next page.
