1.3) Indoor electric control (Take cassette and duct as example)
1. EXY (NET) ― Net control socket
X, Y, E of all air-conditioners are connected together in Bus to the X, Y, E of CCM.
2. CN15 (ENC2) ― Number Setting port from outside
It has same function as ENC2 ((NUM_S) ― Number Setting (for outdoor), the difference is
that it is suitable for some special indoor unit such as one-way cassette (compact), which has no
enough space to operate ENC2 ((NUM_S) ― Number Setting (for outdoor), so we support this
port to extend Number Setting Switch outside.
