9-3-1 Additional functions
Operation by power supply [HRV unit]
Purposes and functions
• The HRV unit is operated by "On / Off" of the main power
breaker. This is possible only for the independent
operation system. (When the main power is disconnected,
the transmission error will be displayed if the HRV unit is
interlocked to the indoor unit or controlled by the
centralized control.)
Cautions
1. Install insect control wire net on the air intake and
exhaust openings. (If the power is disconnected when
the damper is open, the damper remains open and the
insects may get into the room.)
2. When you install the remote control, it is possible to
have normal operation after the electric power
is supplied.
