For this explanation, we'll describe the input value as 0xAABBCCDD
Where:
AA = Byte 1 (unused, left as 00)
BB = Byte 2 (sets the temperature threshold)
CC = Byte 3 (sets the degree scale as °C or °F)
DD = Byte 4 (unused, left as 00)
Part 1: The temperature setting is set by value * 0.1, so the value 2.0 would come from the value 20. To proceed with calculating this, we must convert decimal to hexadecimal which would give the value of 0x14 (you can use any decimal to hexadecimal calculator to confirm this or to generate any value that you want).
In this case, value BB = 14
Part 2: The scale is determined with 1 of 2 values. The value 1 is Celsius (°C) while the value 2 is for Fahrenheit (°F). The value for °C we want is 1.
In this case, value CC = 01 (if we wanted °F, this would be 02).
Part 3: Combine hexadecimal values together.
AA = 00 (this is unused so 00 is used)
BB = 14 (from Part 1)
CC = 01 (from Part 2)
DD = 00 (this is unused so 00 is used)
