Test Run - Daikin VAM150FC Installation Manual

Zone 2
The HRV units operate in the zone-linked mode, as described in the
section, "Linked control with more than two groups" on page
the initial setting, follow the procedure described in that section.
I
It is necessary to assign a central control group number to each
HRV unit and air conditioner.
Regarding the setting of the group number, refer to the section on
"the centralized control group number setting" in the operating
instructions of the Centralized controller. Refer to the section
""All"/"individual" control" on page 17
I
For the ventilation air flow setting, follow the procedure
described in the section ""All" control" on page
I
For the zone setting from the centralized controller, refer to the
operating instructions of the centralized controller.
I
The centralized controller can be used to control the individual
units in the zone for ventilation operation.
Remote control
Monitor of operation
The operation of the HRV can be monitored from the outside by the
connection of the adaptor PCB for remote control BRP4A50A
(option).
Be sure to connect the terminal strip on the adaptor PCB for remote
control BRP4A50A (option).

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 voltage and low current (16 V, 10 mA) is
formed between 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
odour.
Necessary parts
Operation contact of exhaust ventilating fan (Field supply)

EST 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.
