2) Connecting procedures
•
The remote controller cord may be extended up to 500 m. Since the
remote controller cord supplied with the unit is 10 m-long, use those
electric wires or (two-core) cables of 0.3 mm
2
to 1.25 mm
2
for exten-
sion. Do not use multi-conductor cables to prevent possible malfunc-
tion of the unit.
1
Connect the remote controller cord to the terminal block for the
lower case.

No polarity!
Caution:
Do not use crimp-style terminals for connection to the remote con-
troller terminal block to eliminate contact with the boards and result-
ant trouble.

Wiring port for direct installation of remote controller on the wall
(In case of open wiring)
•
Cut off the thinner portion (indicated by the shaded area in the
diagram) on the upper case with a knife, nipper or other such proper
tool.
•
Through this portion, run the remote controller cord connected to
the terminal block.

2) Connecting procedures
3
Connect the lower case connector to the upper case connector
CN1.
Caution:
•
After connection, do not allow the remote controller to hang as
shown in the illustration to prevent broken cord and/or malfunc-
tion of the unit.
•
Remember to run the cord through the hook (for cord tying). If
the cord is left out from the hook, the weight of the remote con-
troller will be directly applied to the terminal board, thereby caus-
ing broken cord.
•
Do not attempt to remove the board protection sheet and the board
to prevent possible malfunction.
•
Do not touch the temperature sensor. Touching the sensor may
result in failure of correct detection of room temperatures by the
remote controller.
