7.2.2 Zone Control System (Central Remote Controller DCS302B61)
Purposes and
Functions
A maximum of 64 groups can be controlled On / Off individually by one controller. And also
the central remote controller can control the On / Off operation of the units in each zone
collectively. (It also can control the interlocked operation as well as the independent
operation within the same zone.)
If the zone setting is not required, or if you like to operate the HRV unit whenever one of
indoor unit of any group connected to the central transmission line is in operation, refer to
the applied system.
Cautions:
1. It is necessary to assign a central control group number.
2. If you operate the HRV unit interlocked to the operation of indoor unit, please set the same
zone number. At that time, it is necessary to set the zone operation on the HRV unit.
3. It is not possible to operate On / Off from the remote controller for the HRV unit in zone 1.
4. It is not necessary to set the zone operation mode in zone 2, which is already set at the
factory.
