2. Pull out 4-core twisted pair line in mounting hole and then make it through the rectangle hole at the back
of controller’s soleplate.
3. Joint the controller’s soleplate on wall face and then x it in mounting hole with screws M4×25.

Caution:
During connection of wirings, pay special attention to the following items to avoid interference of
electromagnetism to unit and even failure of it.
1. To ensure normal communication of the unit, signal line and wiring (communication) of wired controller
should be separate from power cord and indoor/outdoor connection lines. The distance between them should be
kept 20cm in min.
2. If the unit is installed at the place where there is interference of electromagnetism, signal line and wiring
(communication) of wired controller must be shielded by twisted pair lines.
