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 control or the unified On / Off control.)
Cautions
1. Adapter PCB can be installed in any unit connected to
the central transmission line.
2. It cannot be used with other central control.
3. The setting of group number is not required.
4. The HRV unit judges the ventilation mode, individually.
Example control wiring
Connecting line can be
extended up to 150 m
maximum.
