•Controller name, symbol and allowable number of controllers.
| Name | Code | Possible unit connections | |
Outdoor unit | Main unit | OC | – (*2) | |
Sub unit | OS | – (*2) | ||
| ||||
Indoor unit | Indoor unit controller | IC | 1 to 32 units per 1 OC (*1) | |
Remote controller | Remote controller (*1) | RC | 2 units maximum per group | |
Other | Transmission booster unit | RP | 0 to 1 unit per 1 OC (*1) |
*1 A transmission booster (RP) may be required depending on the number of connected indoor unit controllers.
*2 OC and OS of the outdoor units in the same refrigerant system are automatically identified. They are identified as OC and OS in descending order of capacity. (If the capacity is the same, they will be in ascending order of their address number.)
Example of a group operation system with multiple outdoor units (Shielding wires and address setting are
GB
necessary.)
