• Fan speed can be set at the initial setting.
• Both simultaneous operation by air conditioner’s
remote control and independent operation by HRV

Connectable
Indoor unit VRV (all indoor unit), SkyAir (Optional connecting PCB is required.)
Daikin’s HRV Other types
Dust does not fall off from the air filter because the air supply fan
of the interlocked indoor unit remains activated even when the
HRV is operated independently.
If conventional HRV, with exclusive remote control, is directly
connected to indoor unit of air conditioner, dust may fall off from
air filter when air conditioner is OFF.

2 - 2 Energy Saving
NOTE
1 The total heating / cooling load may vary depending on the climate or the other environmental conditions.
HRV unit recovers the thermal energy during cooling / heating operation of air
conditioner. HRV reduces the cooling / heating load drastically and enhances the
heating / cooling efficiency.
Proper use of Heat recovery ventilation and normal ventilation saves energy.
When the cooling operation is required in winter, use of heat recovery ventilation is not
efficient because the outdoor air temperature is normally lower than that of the indoor.
Thus, the proper use of ventilation mode enhances the heating / cooling efficiency.
Automatic Ventilation mode changeover
Refer to the CONTROL for the mode changeover.
The load is reduced at startup of the air conditioner by the following control.
Before the working hour, the room air is clean.
Therefore, the startup of HRV can be delayed.

2 Features
2 - 3 Night time free cooling operation
Automatic heat purge function at night
The nighttime free cooling is an energy-conserving function which works at night when the air conditioners is off, reducing the cooling load in the
morning when the air conditioner is turned on. This is mainly for rooms that contain office equipment, which raises the room temperature.
• Nighttime free cooling only works during cooling and when connected to Building Multi or VRV systems.
• Nighttime free cooling is set to “off” in the factory settings; so request your dealer to turn it on if you intend to use it.

(e) Operating state of Total heat exchanger
Explanation of nighttime free cooling operation image
The unit compares the indoor and outdoor temperatures after the air conditioning operation stops for the night. If the following conditions are satisfied,
the operation starts, and when the indoor temperature reaches the air conditioning setting, the operation stops.
Conditions
2 the indoor temperature is higher than the air conditioning setting and
3 the outdoor temperature is lower than the indoor temerature.
If the above conditions are not satisfied, reevaluation is made every 60 minutes.
NOTE
The Nighttime free cooling operation works when the HRV unit is off. Therefore, it is not possible to stop the night purge operation, though the
forced off is input from the optional controllers for centralized control.
Test run
After completing the installation of the system, check again to make sure that no error was made in wiring or switch setting on the printed
circuit boards of the HRV units.
Then, turn on the power of the HRV units. Refer to the manual of the remote controller of each unit (remote controller for air conditioner, central control
unit, etc.) for conducting a trial operation.

2 - 4 FRESH-UP operation
Both the excessive supply mode and the excessive exhaust mode are selectable.
This function creates a more comfortable air environment.
2-5 Element (HEP element)
Material
The heat exchanger element adopts a new paper of high permeability. The material recovers exhaust humidity at a speed of 2 times of the previous
model.
The material is flame-retardant for safety.
The fungiproof design also keeps the air clean.
Structure
The heat exchanger element is designed without moving parts for higher durability and reliability.
The supply air passage and the exhaust air passage are arranged in right angle to prevent the supply and exhaust air from getting mixed.
Supply Fresh-up
(Excessive outdoor air supply)
Exhaust Fresh-up
(Excessive Exhaust air supply)
Detail Supply air volume can be set at a higher level than the
exhaust air by the remote control.
Exhaust air volume can be set at a higher level than the
supply air by the remote control.

Notes
(1) Operation sound is measured at 1.5m below the center of the body.
(2) Air flow rate can be changed to Low mode or High mode.
(3) Normal amplitude, input and efficiency depend on the mentioned conditions.
(4) Sound values are measured in an anechoic chamber. Operating sound level generally becomes higher than this value depending on the operating conditions, reflected sound, and
peripheral noise.
(5) The noise level at the air discharge port is about 8dB higher than the operating sound of the unit.
(6) The specifications, designs and information here are subject to change without notice.
(7) Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
(8) Maximum allowable voltage range variation between phases is 2%.
(9) MCA/MFA: MCA = 1.25 x FLA(FM1) + FLA(FM2); MFA ≤4 x FLA; (VAM2000 is regarded as 2x VAM1000)
(10) Select wire size based on the value of MCA
(11) Instead of a fuse, use a circuit breaker
(12) MCA = 1.25 x FLA (FM1) + FLA (FM2)
(13) MCA represents maximum input current. MFA represents capacity which may accept MCA.
(14) Next lower standard fuse rating minimum 16A

NOTES
1. Voltage range:
The units are suitable for use on electrical systems where the voltage, supplied to unit terminals, is not below or above listed range limits.
2. The maximum allowable voltage variation between phases is 2%.
3. MCA = 1.25 x FLA (FM1) + FLA (FM2)
MCA represents maximum unit input current.
MFA represents acceptable capacity for MCA.
(Next lower standard fuse rating minimum 16A).
4. Select a wire size based on the MCA value.
