|
|

* + Error
|
|
*
|
|
* At present there is no write access for target
|

* room temperature and target water temperature. These

* device.

|

* of read requests. However, a maximum of 6 registers
|
|
* can be read simultaneously. With the given set of
|
|
* addresses it is not possible to reasonably group the
