¹ All temperature registers are expressed in °C regardless what Temperature units (register 179) is set to.
Temperature range is -40°C to 130°C with values given in 0.1°C units (for example, 32.0°C = 320). A temperature
that is NOT applicable in this SOLA, i.e., not enabled, has a value of 0x8FFF. This temperature setting is denoted
as “UNCONFIGURED” at the user interface.
