Purposes and functions
When the HRV unit is interlocked to 2 or more
group of indoor units, the HRV unit operates, if
one of indoor unit in groups is in operation. The
HRV unit can also be operated independently by
remote control for indoor unit, even if the indoor
unit is not in operation.
Cautions
1. It is not necessary to set the group number for
central control.
2. One adapter PCB for remote control should be
installed in the one of the unit connected to the
central transmission line.
(When you install an adapter PCB for remote
control in the indoor unit, select the applicable
model number of Adapter PCB to be installed.)

The central transmission line can be extended up to
