■ VAM150F, VAM250F, VAM800F, VAM1000F CAUTIONS on installing the ducts ■ The parts marked with (*) are effective in reducing blowing noise. ■ When using the unit at a quiet place, use the optional silencer box and flexible duct at the part of the air discharge outlet on the indoor side “SA” (supply air to room) of the unit, to counter the noise.
Duct connection 3 Do not connect the ducts as follows 6 7 Extreme bend Do not bend the duct over 90° Multi bend 8 9 6 Reduce the diameter of the duct to be connected. Do not reduce the duct diameter halfway. 1 The minimal radius of bends for flexible ducts are as follows: 300 mm duct: 200 mm diameter 375 mm duct: 250 mm diameter 2 To prevent air leakage, wind aluminum tape round the section after the duct connecting flange and the duct are connected.

ELECTRIC WIRING Component electrical specifications VAM Before obtaining access to terminal devices, all power supply circuits must be interrupted. Connection of wiring ■ Connect the wires in accordance with the diagram of each system. ■ All wiring must be performaed by an authorized electrician. ■ All field supplied parts and materials and electric works must conform to local codes.

Local setting Using the remote controller of the VRV-system air conditioner to make HRV unit settings Initial setting 1 Mode nos. 17, 18 and 19: Group control of HRV units. 2 Mode nos. 27, 28 and 29: Individual control Operating procedure The following describes the operating procedure and settings. 1 Press the INSPECTION/TRIAL button for more than four seconds with the unit in the normal mode to enter the local setting mode. 2 Use the TEMPERATURE ADJUSTMENT button to select the desired “mode number.
Example When adjusting the ventilation air flow to low setting in the group setting mode, enter the mode No., “19” setting switch No., “0” and setting position No., “01”. List of Settings Mode No. Group settings Setting position No.(Caution *1.) Individual settings Setting switch No.
For “FRESH UP” operation, Operation with the remote control exclusively for Air conditioning operation HRV units. (BRC301B61) • For non-independent systems, starting/stopping operation and timer operation may not be possible. Use the air conditioner remote control or the Centralized controller in such cases. 5 7 1 2 4.
12. Push the button “ Wiring and connections in combination with “VRV-SYSTEM” ” and set the time. Each time when “ ” is pushed, the time advances one hour. Each time when “ ” is pushed, the time goes back one hour. 13. Push the button “ ”. Then, the reservation is finished. Either “ ” or “ ” changes from flashing to lighting. After the reservation is finished, the remaining time is indicated in the display. For cancelling the timer operation, push the button “ again. The indication disappears.
■ Connecting the remote controller for HRV Direct duct connection system for 1-group operation system The remote controller for HRV cannot be used for starting/stopping operation or for timer operation. (The centralized control indication will be lit.) To set pre-cool/pre-heat function settings, change the remote control air flow rate setting from medium (M) to high (H), etc., perform initial settings from the remote controller for HRV.
Procedure 1 Turn off the main power. 2 Connect the air-conditioner remote controller. HRV 1 P1 P2 1 ■ The Adapter PCB for remote control and schedule timer cannot be used together. ■ The Adapter PCB for remote control can be mounted on the electric component mounting base of either the HRV unit or air conditioner.
Procedure 1 Turn off the main switch of the HRV-1 and On/off controller. 2 Connect the air conditioner’s remote controller. ■ A maximum of 64 air conditioners and HRV units can be connected to the F1 and F2 terminals. ■ The HRV units will turn on and off in according with the zone operation command from the centralized controller. Zone 2 1 P1 The HRV units operate in the zone-linked mode, as described in the section, "Linked control with more than two groups" on page 14.
NOTES Fresh-up operation Purposes When Combined with a local ventilating fan (such as the one in toilet and kitchen), the air flow rate of HRV is balanced by either fan operation or exhaust operation. However, a circuit with voltaged and low current (16V, 10mA) is fromed between the JC and J1, so a relay with low-load contact point must be used. Functions The unit performs overcharged operation to prevent back flow of odor.
