+It says to BigRelay (0x9c) that register 10(0x10) has to be zero (0x00).
 So in other words all the relays on the BigRelay have to be turned off.
 ( You can also change register 10 into num, and put it under the turn on command. )

+The %d is for showing it in decimals and %u for showing in unsigned decimals. ( if you do %02d 1 will become 01. )
 "num -0x20+1" counts 20 hexadecimals off num and after that counts 1 up. So, example: 25-20=5+1 = 6.
 ( if you count 19 or 21 hexadecimals down you would get a really different result. )
