The T/H sensor address has been set.
Set the device address for a T/H sensor by operating the DIP switch on the
sensor. DIP switches 1–6 are used to set the device address, DIP switch 7 is
reserved, and DIP switch 8 is used to switch the temperature display mode.
The device address is set in binary mode. 1 is the least significant bit, and 6 is
the most significant bit. ON indicates 1, and OFF indicates 0. The address
range is 1 to 63.
The numbers indicate the DIP switch settings of the ambient T/H sensors.
