Caution:
Do not use anything other than the correct capacity breaker and fuse. Us-
ing fuse, wire or copper wire with too large capacity may cause a risk of
malfunction or fire.
10.2. Connecting remote controller, indoor
and outdoor transmission cables
(Remote contoroller is optionally available.)
•
Connect unit TB5 and outdoor unit TB3. (Non-polarized 2-wire (shield))
The "S" on unit TB5 is a shielding wire connection. For specifications about
the connecting cables, refer to the outdoor unit installation manual.
•
Install a remote controller following the manual supplied with the remote con-
troller.
•
Connect the "1" and "2" on unit TB15 to a MA remote controller. (Non-polar-
ized 2-wire)

C MA remote Controller
E TB2 (Power supply wiring)
Note:
Ensure that the wiring is not pinched when fitting the terminal box cover.
Pinching the wiring may cut it.
Caution:
•
Use wire with supplemental insulation.
•
Input to TB142A, TB142B, and TB142C should not carry voltage.
•
Cables from equipment connected to external input/output should have sup-
plemental insulation.
•
Use a single multiple-core cable for external input/output to allow for connec-
tion to the PG screw.
Caution:
Wire the power supply so that no tension is imparted. Otherwise discon-
nection, heating or fire result.

10.3. External input/output function

Preset temperature input (external analog input: 4mA-20mA)
External input is input through CN421, CN422 on the circuit board. (Fig. 10.3.1)
Use the supplied connector.
If no temperature settings are made via the MA remote controller, the temperature
changes with the current.
Refer to the instructions manual that came with the MA remote controller for how
to make the settings.
4 mA → 10 °C
20 mA → 70 °C
External output terminal
External output terminal (refer to Fig. 10.3.2) is ineffective when the circuit is open.
Refer to Table 10.3.2 for information about each contact.
The current in the circuit to be connected to the external output terminal must be
0.6A or less.

The piping 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
conditions.
