(HC0230)
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

Night time free cooling operation
Automatic heat purge function at night
1 2
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.

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.

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

The air suction and discharge grille may give out operating sound higher by 8 to 11 phons than of the HRV units body. When installing this unit in a quiet place, take measures to reduce operating sound.
13 - 2 - 1 Points for reducing operating sound
Note: Some sound-insulating ceilings are not very effective in reducing low-frequency element of the operating sound.
1. Operating sound heard from the air discharge outlet can be reduced just by applying sound-insulating material to the SA (indoor air supply) duct. HRV units

2 Place a sound-reducing material under the source of the
operating sound.
Air suction / discharge grille
Note: When using a sound-insulating sheet, it is necessary to have the entire body of the unit covered with it. Note, however, that some models do not allow the use of a sound-insulating sheet because it may badly affect the ventilation of their radiation heat.

4. Installation of the unit with the source of its operating sound located at a corner of a room will be a partially effective sound reduction measure; it will keep persons in the center of the room free from the annoying operating sound, with those in the corner of the room kept annoyed by the operating sound. To avoid this, try to find the best installation place from which the operating sound is least heard by everyone in the room.

Direction of air flow
(Indoor side)
Because the air flow shown in Fig.1 is generated when centralized OA and EA pipings for two or more HRV units normal air flow cannot be maintained. If a back flow prevention damper is installed in the duct on OA and EA side of each HRV units (Fig.3), costs will increase as compared with the case a duct is installed for each body. It is therefore recommended that a duct be installed for each body. (Before installing the back flow prevention damper, contact our engineering section.)

: Damper opened : Damper closed
(HC0063)
In the above duct system diagram, if a damper is not provided and No.1 unit is operated with No.2 unit being stopped, the air flows in the direction indicated by a broken line, the amount of the air supplied from outside to OA side is decreased, and the air is discharged from the discharge grille of EA side. Therefore, the air will not flow into the normal direction.

(HC0064)
In the above duct system diagram, if a back flow prevention damper (field supply) is installed on each duct on OA and EA sides and the damper interlocked to the operation signals of HRV units, faults such as those shown in Fig.1 can be eliminated and the normal air flow maintained. (Note, however, that the above does not apply to the standard duct system.)

Installation
13 - 4 Cautions 1. Install the unit on a rigid and stable place. Refer to the specification and weight of the unit.
When a smoke back flow prevention damper is installed Smoke back flow prevention damper
Use suspension bolts for installation. Confirm that the place for installation can stand the weight of the unit. If not, reinforce the place with beams, etc. and install the suspension bolts. If the strength of the place for installation is not sufficient, the place resonates to the vibration of the unit and abnormal noise may be transmitted.

Fan Centralized duct (Vertical hole)
2. Install a service space and an inspection hole. Refer to the outline drawing for details.
Cross sectional area : Less than 250 cm2
Be sure to provide a service space and an inspection hole for inspection of air filter, heat exchange element and fan. HRV units require one inspection hole.
Steel plate of 0.8 mm thick or more
Inspection hole (450·450 or more)
(HC0066)
3. Bellows may not be able to use depending on the local regulations. (In the case in Japan) Some local regulations may not allow the use of bellows in view of the safety for fire prevention. Before using the bellows, contact administrative agencies or fire department in your district. Note that bellows are not allowed in Tokyo in accordance with the Fire Prevention Act of Tokyo.
4. When exhausting air into the centralized duct (vertical hole), install a riser duct of steel plate of over two meters long inside the vertical hole or install an approved smoke back flow prevention damper. (In the case in Japan)
When exhausting air into centralized duct (vertical hole), the Building Standards Act requires that the duct must be capable of preventing fire from expanding through the duct should a fire break out. When a riser duct of steel plate of 2 m long is installed
Fan Centralized duct (Vertical hole) Cross sectional area : Less than 250 cm2 Steel plate of 0.8 mm thick or more
5. Air filters are provided on the air intake side and exhaust air side. Be sure to install these filters. Air filter cleans the air and prevents clogging of the element, and must be installed properly.
6. Confirm the using conditions of HRV units before installation. Ambient conditions for use: –10°C to 50°CDB at 80% RH or less
Outdoor air temperature condition When used below –10°C, indoor air temperature varies greatly from outdoor air temperature and frost may form on the heat exchange element depending on conditions of temperature and humidity. Further, the frost formation may be frozen. The frozen frost melts during the day as the temperature rises but the heat exchange efficiency drops before the frozen frost is melted.
2 m or more
Rigid mounting
Caution • Installing a 2 m exhaust duct in a centralized duct involves difficulty in construction and maintenance, and is not practised generally. In actual installation, the approved smoke back flow prevention dam per is used, Use Daikin's optional smoke back flow prevention damper.
As a countermeasure, preheating of the air on low temperature side is considered. In a place where the temperature exceeds 50°C, deformation of resin parts such as air filter and reduced life of motor and electric parts due to deteriorated insulation are considered.

*1. Independent operation for ventilation is possible, if collective zone interlock setting is “ON” with the indoor unit in the same zone. *2. It is possible by the initial setting. *3. Display of malfunction code only. *4. The meaning of total evaluation AA: Interlocked operation with energy saving and changeable of Ventilation mode / Air flow rate BB: Interlocked operation with energy saving and no changeable of Ventilation mode / Air flow rate CC: No interlocked operation with energy saving and changeable of Ventilation mode / Air flow rate DD: No interlocked operation with energy saving and no changeable of Ventilation mode / Air flow rate *5. Interlocked operation setting must not be done for individual zone. (Because there is no unit to combine in zone except 1unit.)

It is necessary to install the remote control for the transmission line.
The centralized transmission line should be connected to the indoor unit.
• When you connect the transmission line for the remote control, the remote control should be installed on the transmission line.
Example of control wiring
• If the HRV unit is interlocked to the centralized control, the central transmission line should be connected to the terminal no. F1 and F2 of indoor unit.
