The No. 1 cool/heat unified address is expressed as a binary number
consisting of the lower 6 digits. (0 - 63)
In the figure 1, the address is 010110 (binary number), which
translates to 16 + 4 + 2 = 22 (base 10 number). In other words, the
address is 22.
The number of terminal blocks for No. 12 and 13 is expressed as an
8-digit binary number, which is the combination of four upper, and
four lower digits for No. 12 and 13 respectively. (0 - 128)
In the figure 2, the address for No. 12 is 0101, the address for No. 13
is 0110, and the combination of the two is 01010110 (binary number),
which translates to 64 + 16 + 4 + 2 = 86 (base 10 number). In other
words, the number of terminal block is 86.
