External input terminal
The wire length must be within 100 m.
External input terminal (refer to Fig. 10.3.3) is ineffective when the circuit is open.
Refer to Table 10.3.3 through Table 10.3.5 for information about each contact.
Only the "pump interlock" function is ineffective when the circuit is short-circuited.
Connect a relay circuit to the external output terminal as shown in Fig. 7.4.1.
The specifications of the relay circuit to be connected must meet the following condi-
tions.

Contact rating current 0.1A
Minimum applicable load 1mA at DC

10.4. Setting addresses

(Be sure to operate with the main power turned OFF.)
[Fig. 10.4.1] (P. 4)
<Address board>
• There are two types of rotary switch setting available: setting addresses 1 to 9 and
over 10, and setting branch numbers.
1 How to set addresses
Example: If Address is "3", remain SWU2 (for over 10) at "0", and match
SWU1 (for 1 to 9) with "3".

11. Information on rating plate

Warning:
Do not use refrigerant other than the type indicated in the manuals provided with the unit and on the nameplate.
- Doing so may cause the unit or pipes to burst, or result in explosion or fire during use, during repair, or at the time of disposal of the unit.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held responsible for malfunctions or accidents resulting from the use of the wrong type of refrigerant.

units (outdoor/indoor units).
2 How to set branch numbers SWU3 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end connection
number. Remain other than R2 at "0".
• The rotary switches are all set to "0" when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set
them referring to the DATA BOOK.
