Control System

9-3

Applicable patterns

9-3-3

Central control system (DCS302B61)

Collective operation (Schedule timer DST301B61)

Purposes and functions

• A maximum of 128 units can be controlled the collective

operation / stop by weekly schedule.

Cautions

1. The setting of group number for central control is not

required.

2. The HRV unit judges the ventilation mode, individually.
3. The power supply for the schedule timer can be supplied

from the PCB of the unit. (X18A for the indoor unit and
X11A for the HRV unit)

Example of control wiring

Switch setting of the HRV unit

The initial setting is required by the remote control for the
indoor unit.
