Indoor Unit Wiring
1. Prepare the cable for connection
a. Using wire strippers, strip the rubber jacket
from both ends of the signal cable to reveal
about 15cm (5.9") of the wire.
b. Strip the insulation from the ends of the wires.
c. Using a wire crimper, crimp the u-lugs to
the ends of the wires.
2. Rotate the sensor device's installation bearer to
the other side. Then remove the cover of the
electrical box. (Also, remove the electrical box
also if its capacity is 18000btu/h and has
networking functionality.)
3. Connect the u-lugs to the terminals.
Match the wire colors/labels with the labels on
the terminal block, Firmly screw the u-lug of
each wire to its corresponding terminal. Refer
to the Serial Number and Wiring Diagram
located on the cover of the electric control box.
