19.6.15 Message: Setting the Heating Mode
The heating of the precipitation and the wind sensors can be configured in different operation
modes (see chapter 10.4). Depending on the actual variant of the Smart Weather Sensor
(WS100-UMB ...WS800-UMB) only certain combinations of operating modes are available.
The Smart Weather Sensor evaluates the valid combinations from the device heating mode
requested in the command automatically.
