Single-group interlocked operation (Basic pattern)
Single-group interlocked operation (Direct duct connection)
Purposes and functions
The remote control for indoor unit can control the
interlocked operation with the HRV unit, and it can
make an initial setting of the ventilation flow rate,
the ventilation mode changeover and fresh-up
operation. The HRV unit can independently be
operated, even if the indoor unit is not in
operation.
Note
1. The remote control should be connected to the
terminal no. P1 and P2, the same as the group
control wiring of indoor units.
2. Since this is two remote control system (for Indoor
unit and HRV unit), the Master / Slave setting is
required.
Example of control wiring
Switch setting for HRV unit
No change is required. (as per factory setting)
Optional accessories required
None
Purposes and functions
The operation of HRV unit is interlocked to the
indoor unit connected by the duct, which has a
fresh air intake.
It can reduce the number of outlets for supply air.
The HRV unit cannot be operated independently
to prevent a reverse stream of fresh air to the
suction side of the indoor unit, unless the fan of
indoor is in operation.
Note
1. The amount of fresh air to the indoor unit should
be less than 20% of the total air volume of the
indoor unit. (If the amount of fresh air is too much,
the capacity of the indoor unit may reduce and the
operating sound might be higher.)
2. The HRV unit can be operated independently, if the
fan of indoor unit is in operation.
3. Since this is two remote control system (for Indoor
unit and HRV unit), the Master / Slave setting is
required.
