Group Interlock Control
7.1.1 Single-group Interlocked Operation (Basic Pattern)
Purposes and
Functions
The remote controller 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 controller 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 controller system (for Indoor unit and HRV unit), the Master / Slave
setting is required.
