Daikin FD10KY1 [20/40] Abundance of functions that provide comfortable air conditioning in stores and offices
C o m fo rt
A uto -s w ing
Air discharge direction angle can be set (fixed setting)
Dr a ft pre ve nt io n func t io n (heating)
You can increase fan speed approximately 10%
higher than the "high" setting.
M o uld pr e v e ntio n
H igh fa n s pe e d m o d e
Dehumidification is microprocessor controlled to
prevent uncomfortable changes in air temperature.
Useful for reducing uncomfortable humidity without
uncomfortable cooling.
P rogra m m e " Dry "
Delivers air-conditioning comfort all the way down to
the floor in air-conditioning zones with high ceilings.
H igh-c e i ling a ppli c a tio n
Uncomfortable cold air draft is not discharged when
heating operation starts or when switching to heat
after defrosting.
H o t s t a rt (after defrost)
Efficient cooling even in winter when indoor temperatures
are higher than those outside, such as in underground pub-
lic spaces or offices with many computers.
Y e a r -rou n d c o o l in g a pplic a ble
Operation starts when the preset time of the ON
timer elapses and stops when the preset time of the
OFF timer elapses.
T im e r s e le c to r
Sanitary filter has mould-resistant treatment.
M o u l d-re s is t a nt tr e a tm e nt fo r fil t e r
Mould-proofing maintains hygiene by preventing
growth in highly humid conditions.
M o u l d-pr o o fin g dr a in pa n
O pt io ns
Two types are available: 65% and 90% colorimetry.
H igh-e ffi c i e n c y fi lte r u nit
Requires no maintenance for about 4 years* (10,000 h) in stores
and offices.
* For dust concentration of 0.15 mg/m

U ltr a lon g -li fe filt e r
You can provide air-conditioning with fresh air from
outside. Convenient for places where a ventilation
fan cannot be installed.
F r e s h -a ir i n t a k e k it
W or k a nd S e rv ic ing
Steeper gradient realises more
efficient condensate drainage.
High-lift is especially useful for
long lengths of drain piping.
Dr a in pu m p m e c h a nis m
Maintenance is not required for one year (two years
when a ceiling mounted cassette type is used).
L ong-l ife filt e r
Daikin's innovative air discharge mechanism keeps
airflow away from the ceiling. Ceiling cleaning is
less frequently required.
C e ilin g s o i ling pr e v e n tio n fu n c tio n
If refrigerant piping length does not exceed 30 m,
there is no need for on-site gas charging.
P re c ha r g e d fo r u p t o 3 0 m e t r e s
If there is a malfunction elsewhere in the system, the fan
or compressor can still be operated.
E m e r g e nc y ope r a t io n
The operating parameters of indoor and outdoor units,
and sensor data at critical locations throughout the
system, are constantly monitored using a microcomputer.
To facilitate quick response in the event of a
malfunction, a message appears on the LCD of the
remote controller and an LED on the unit illuminates.
S e lf dia gno s is f u n c tio n
C o ntr o l fe a tur e s
If there is a power outage while the equipment is op-
erating, operations will restart in the same mode as
before the power cut when electricity is restored.
A uto -re s ta rt
A uto c o o l/he a t c ha ng e -ov e r
Using 2 remote controllers you can operate the
equipment locally or from a remote location.
C ontr o l by 2 re m ote c o ntr o ll e r s
Note: When a wireless remote controller is used, remote control by
two remote controllers is not possible.
You can turn up to 16 indoor units on/off with a
single remote controller. (When using connected
indoor units, the settings must all be the same and
on/off will be simultaneous.)
C ontr o l by 1 re m ote c o ntr o ll e r
E x t e r n a l c o m m a n d c ont r o l
Optional central remote controller enables
centralised control of up to 1024 indoor units (64
groups) from up to 1 kilometer away.
C e n t r a l r e m o t e c o n t ro l
Enables interlocking control with external
equipment such as heat reclaim ventilation (HRV).
I n t e r l o c k c ontr o l
Delivers comfortable air-conditioning to all areas,
near to and far from the air-conditioner.
To prevent cold air drafts, automatically adjusts airflow
to horizontal vector when heating initially starts or
when the thermostat turns off.
Detects difference in preset temperature and actual
room temperature and automatically switches to
cooling or heating accordingly.
Operation and surveillance is carried out using the
contact signal from the operation control box in the
building surveillance (security) room.
(1) Air direction in
standard position
(2) Air direction in draft
prevention position
(3) Air direction in ceiling
soiling prevention position
You can freely set 3 air discharge positions by
remote controller.
S w ing p a tt e r n s e le c tion
(draft prevention, standard, ceiling soiling prevention)
High setting provides maximum reach while low
setting minimises drafts.
S w itc h a ble fa n s pe e d
O the rs
To achieve increased durability by improved resistance to salt corro-
sion and atmospheric pollution, coated PE fins (with special acryl pre-
treatment) are used for the heat exchanger of the outdoor unit.
In high corrosive areas, regular maintenance needs to be carried out.
P E fin
Simultaneously operates 2–4 indoor units
with a single outdoor unit.
T w in / t r ip le / do u b le t w in m u l t i o pe ra tio n
37 38
Use the temperature-sensor in the
indoor unit when controlling air
conditioning from another room.
T w o s e le c t a ble t e m pe r a t u r e -s e n s o rs
Temperature-sensors are included in the indoor unit and op-
tional wired remote controller.
Temperature sensing closer to
target area is possible to further
Note: Wireless remote controllers have no
temperature-sensor.
(Heat pump only)
•
Heat pump/RY71—140LU: possible up to -5°C
•
Cooling only/R71—140LU: possible up to -15°C
• The year-round cooling kit is required as option.
Applicable for ceiling mounted cassette type and ceiling mounted
cassette corner type.
Abundance of functions that provide comfortable
air-conditioning in stores and offices.
Note: Some features only available on selected models. See model pages for full list of features applicable to each unit.
Applicable for wall mounted type
Note:When units are installed on high ceilings, depending on the model, various restrictions
concerning maximum height, air discharge direction, and choice of options may apply.
The filter sign warns you when it is time to clean the filter.
*When using a wired remote controller the sign is displayed in the LCD. When using a
wireless remote controller the filter sign lamp illuminates on the signal receiver unit.
F ilt e r s ign
L ow ga s pr e s s ure de te c tion
Insufficient gas charging is normally hard to detect.
During post-installation trials and regular inspection
procedures, the refrigerant level is monitored by
microprocessor to maintain proper gas
pressure.Reliability is assured and maintenance and
inspection can be carried out more quickly.
(Horizontal air disc harge)
(Applies to R(Y)71LU–140LU)
*Connecting ducts, insect nets, fire dampers, air filters, and other parts should, as
required, be procured locally.
**Outside Air fan interlocked with air conditioning unit is necessary. Optional
PCB(KRP1C63)is required for interlocking.
***It is recommended that the volume of outdoor air introduced through the kit is limited
to 10% of the maximum airflow rate of the indoor unit. Introducing higher quantities
will increase the operating noise and may also influence temperature sending.
