Read only property. Floating point. Returns the temperature higher threshold value. This is set by the ethClient.asmx/SaveTempSensorConfig method.

The sensor does not have to be monitoring enabled for this value to be valid.

If temperature monitoring is enabled, tag will become "too hot" state if temperature is higher than this value by the window amount. Window is 0.6°C for 13-bit sensors and 2°C for 8 and 10-bit sensors.)
