16-bit binary data.

With °C temperature unit, raw data is multiplied by 100. For example, 25.5°C is converted into 2550.

With °F temperature unit, raw data is multiplied by 10. For example, 135.4°F is converted into 1354.

Minus temperature is converted into negative values, represented in 2’s complements.
