15 - 4 Applicable patterns
15 - 4 - 3 Central control system (DCS302B61)
Multi function central c Unified On / Off Control
*1. Independent operation for ventilation is possible, if collective zone interlock setting is “ON” with the indoor unit in the same zone.
*2. It is possible by the initial setting.
*3. Display of malfunction code only.
*4. The meaning of total evaluation
AA: Interlocked operation with energy saving and changeable of Ventilation mode / Air flow rate
BB: Interlocked operation with energy saving and no changeable of Ventilation mode / Air flow rate
CC: No interlocked operation with energy saving and changeable of Ventilation mode / Air flow rate
DD: No interlocked operation with energy saving and no changeable of Ventilation mode / Air flow rate
*5. Interlocked operation setting must not be done for individual zone. (Because there is no unit to combine in zone except 1unit.)
Proper control should be selected according to the functions required.
