15 Control systems
15 - 3 Basic patterns
15 - 3 - 4 Centralized control system
Collective / individual control [Unified On / Off control DCS301B61]
Purposes and functions
1
• One control can controll the operation of
"ON / OFF" of 16 groups of the units collectively or
15
individually.
Also up to 4 controls can be installed in one centralized
transmission line (in one system), which enables to controll
up to 64 groups. (16 groups × 4 = 64 groups)
• The ventilation mode will be selected automatically.
Cautions
1. It is necessary to assign a central group number to each
indoor unit and HRV unit.
2. The operation of HRV unit is not interlocked with the
operation of indoor unit under this control system. If you
like to have a interlocked operation, please consider other
control system.
Switch setting for HRV unit
The initial setting is required by the remote control for indoor unit
or HRV unit.
• No change is required (as per factory setting)
Optional accessories required
• Remote control (Only when you use) BRC301B61
Zone control system (Central remote control DCS302B61)
Purposes and functions
• A maximum of 64 groups can be controlled
On / Off individually by one control. And also the central
remote control can control the On / Oft 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 control
for the HRV unit in zone 1.
4. It is not necessary to set the zone operation mode in zone
