7.5.3 Collective Operation [Adapter PCB for Remote Control KRP2A Series]
Purposes and
Functions
A maximum of 64 groups can be controlled the operation of "ON / OFF" collectively. (For the
individual control, use the central remote controller or the unified On / Off controller.)
Cautions:
1. Adapter PCB can be installed in any unit connected to the central transmission line.
2. It cannot be used with other central controller.
3. The setting of group number is not required.
4. The HRV unit judges the ventilation mode individually.
