Note For Multi System - Daikin FTKS25DVM Operation Manual

Note for Multi System

〈〈
What is a "Multi System"?
This system has one outdoor unit connected to multiple indoor units.
■ When the operational capac-
ity is exceeded
The capacity of units that can be connected and the opera-
tional capacity of the Inverter Multi D series
are as shown below. If the operational capacity is exceeded,
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.
Cooling only
■ 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.
