Data such as addresses and number of units is expressed as binary numbers; the two
ways of expressing are as follows:
The No. 1 cool/heat unified address is expressed as a binary
number consisting of the lower 6 digits. (0 - 63)
In 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 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.
See the preceding page for a list of data, etc. for No. 0 - 25.
