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.
