7.4. Setting addresses
(Be sure to operate with the main power turned OFF.)
1. An address must be set for this system. Furthermore, the address setting range differs depending on the unit.
2. When group operation will be performed, set the addresses according to the table below.
* Group operation means to operate multiple indoor units using one remote controller (or 2 remote controllers).
Note 1: If an address is a duplicate of an indoor unit or outdoor unit of another refrigerant circuit system, set it to another address, which is within the setting range and is
not in use.
Note 2: To set the address of an outdoor unit to “100,” set it as 50.
Note 3: The outdoor units OC and OS of the same refrigerant circuit system are differentiated automatically.
The order of OC and OS becomes from the one with the highest capacity. (If the capacity is the same, the order is from the one with the lowest address.)
Note 4: P750·P900-F model indoor units are equipped with two indoor controllers (control boards). Assign an address so that the No. 2 control board address equals the
No. 1 control board address plus 1. (Factory setting: No.1=01, No.2=02)
3. The address (SW 12 and 11) setting becomes a combination of the 10’s digit (SW 12) and 1’s digit (SW 11) as shown in the examples below.
Example: With the address “03,” the tens digit (SW 12) is “0,” and the ones digit (SW 11) is “3.”
With the address “25,” the tens digit (SW 12) is “2,” and the ones digit (SW 11) is “5.”
4. After setting an address, make sure you enter the address in the Address No. field on the product name plate with, for example, a permanent marker.
7.5. When using other than the internal sensor of the unit to detect the room temperature
•
When the internal sensor of the remote controller will be used, set each of SW 1-1 and SW 3-8 to ON.
•
Some types of remote controller do not have an internal remote sensor. In such a case, set the internal sensor of the unit to detect the room temperature.
•
When using the internal sensor of the remote controller, attach the remote controller to a place where it is possible to detect room temperature.
•
When using the supply air temperature to control the room temperature, the built-in sensor on the remote controller cannot be used.
