Cautions on product corrosion

1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas or alkaline gas, are produced.

2. If the outdoor unit is to be installed close to the sea shore, direct exposure to the sea breeze should be avoided and choose an
outdoor unit with anti-corrosion treatment.

Daikin's HRV (Heat Reclaim Ventilation) recovers heat energy lost through ventilation
and holds down room temperature changes caused by ventilation, thereby maintaining a
comfortable and clean environment. This also curbs the load on the air conditioning
system and conserves energy.
In addition, the HRV is interlocked to Daikin's VRV system, SkyAir and other air
conditioning systems and automatically switches over ventilation mode, further increasing
the effects of energy conservation. HRV operation has been centralized on the air
conditioner remote controller allowing total control over air conditioning and ventilation
with a simple configuration.

Nighttime free cooling operation is an
energy-conserving function that works at
night when air conditioners are off. By
ventilating rooms containing office
equipment that raises the room
temperature, nighttime free cooling
operation reduces the cooling load when
air conditioners are turned on in the
morning. It also alleviates feelings of
discomfort in the morning caused by heat
accumulated during the night.

•Nighttime free cooling operation only works to cool and
if connected to Building Multi or VRV systems.

•Nighttime free cooling operation is set to “off” in the
factory settings, so if you wish to use it, request your
dealer to turn it on.

Centralized Control System

Centralized Control System

A ir C on d it i o ning a nd V e ntila tion

The operation of the air conditioner using the remote controller is interlocked to the operation of
the HRV, greatly simplifying overall system operation. In addition, installation work associated
with the HRV remote controller is not necessary because operations for air conditioning and
ventilation are completely centralized on the air conditioner remote controller. Also, the use of
such a centralized remote controller allows the user to choose a wide range of control systems
that integrate air conditioning and ventilation. Furthermore, by using a variety of centralized
control equipment, the user can build a large, high-grade centralized control system.

Operations and Control with the Air Conditioning Remote Controller

Operations and Control with the Air Conditioning Remote Controller

• Simultaneous ON/OFF of the HRV and indoor unit air conditioner

• Independent operation of the HRV

• Airflow rate switching (initial setting)

• Ventilation mode switching

• Self-diagnosis functions

• Filter sign display and reset

• Timer settings (simultaneous control with air conditioner)

• Pre-cool, pre-heat control settings (initial setting)

• Fresh-up mode switching (Selectable: supply rich mode, exhaust
rich mode; Initial setting)

By combining the (optional) centralized control equipment below, the user can achieve a wide range of
comprehensive centralized control systems for air conditioning and ventilation.

Centralized Controller

• One unit can operate and monitor up to 64 groups (128 units) of HRV
and air conditioner units individually or in batch.

• Allows the user to divide connected HRV or air conditioner units into
zones (up to 64) and control any or all of them.

• Two units of this controller can be linked, thereby allowing centralized
control of up to 128 groups (128 units).

• Centralized control from two places is possible using two units of this
controller.

• Ventilation volume and mode can be controlled for Heat Reclaim
Ventilation.

Unified ON/OFF Controller

• One unit can turn ON/OFF up to 16 groups (128 units) of HRV and air
conditioner units individually or in a batch.

• Lamps display operation and failure status of the connected HRV and
air conditioner units.

• Up to 8 units can be linked to allow centralized control of up to 128 units.

Preventing Dust from Falling with Directly Mounted Ducts

OFF Dust

W it h C o mp e t i t o rs ' P ro du c ts

When conventional total heat exchange units, which
are independently operated using a dedicated remote
controller, are directly connected by a duct, there is a
possibility of dust falling from the air filter of the indoor
unit when the air conditioner is OFF.

Blowing mode No dust is blown out.

W it h the H R V

When the HRV is operating independently, the fan in a
interlocked indoor unit continues turning, so dust does
not fall from the air filter.

A sign is displayed on the remote controller when the air filter needs cleaning.

Note: 1.

Sound level is measured at 1.5m below the center of the body.

2.

Air flow rate can be changed over to Low mode or High mode.

3.

Sound level is measured in an anechoic chamber.
Sound level generally become greater than this value depending on the operating conditions, reflected sound, and peripheral noise.

4.

The sound level at the air discharge port is about 8 dB higher than the unit's sound level.

5.

The specifications, designs and information given here are subject to change without notice.

6.

Temperature Exchange Efficiency is the mean value between cooling and heating.

7.

Efficiency is measured under the following conditions:
Ratio of rated external static pressure has been maintained as follows; outdoor side to indoor side = 7 to 1.

8.

In conformance with JIS standards (JIS B 8628), operating sound level is based on the value when one unit is operated, with the value converted for an anechoic chamber. This is
transmission sound from the main unit, and does not include sound from the discharge grille. Thus it is normal for the sound to be louder than the indicated value when the unit is
actually installed.

9.

Sound level from the discharge port causes the value to be approximately 8 dB (models with the air flow rate of less than 150 to 500 m3/h) to approximately 11 dB (models with the air
flow rate of 650 m
conditions. Please consider noise countermeasures when installing the unit.

10

.

With large models in particular (1500 and 2000 m3/h models), if the supply air (SA) grille is installed near the main unit, the noise of the main unit may be heard from the discharge
grille via the duct, and this will result in a marked increase in noise. In such cases, if peripheral effects are included (such as reverberation of the floor and walls, combination with
other equipment, and background noise), sound level may be as much as 15 dB higher than the indicated value. When installing a large model, please provide as much separation as
possible between the main unit and the discharge grille. If the equipment and discharge grille are near each other, please consider countermeasures such as the following:

•Use a sound-muffling box, flexible duct and sound-muffling air supply/discharge grilles

•Decentralized installation of discharge grilles

11

.

When installing in a location with particularly low background noise such as a classroom, please consider the following measures to avoid transmission sound from the main unit:

•Use of ceiling materials with high sound insulating properties (high transmission loss)

•Methods of blocking sound transmission, for example, by adding sound insulating materials around the bottom of the sound source.
Alternatively, consider supplementary methods such as installing the equipment in a different location (corridor, etc.)

3

/h or more) greater than the indicated value. Furthermore, fan rotation and noise from the discharge grille may increase depending on the on-site duct resistance

Remark)

1. Be sure to provide the inspection hole (450X450 mm) to inspect the air filters, the
exchange elements and fans.

2. It is possible to install the high efficiency filter on the SA face side of heat exchange
element.

PC board adaptor for heater control kit (BRP4A50)

When the installation of an electric heater is required in a cold region, this adaptor with an internal timer function eliminates the
complicated timer connecting work that was necessary with conventional heaters.

Notes when installing

Examine fully an installation place and
specification for using the electric heater based on
the standard and regulation of each country.

Supply the electric heater and safety production
devices such as a relay and a thermostat, etc of
which qualities satisfy the standerd and regulation
of each country at site.

Use a non-inflammable connecting duct to the
electric heater. Be sure to allow 2m or more
between the electric heater and HRV for safty.

For the HRV units, use a different power supply
from that of the electric heater and install a circuit
breaker for each.
