Introduction
|
|
------------
|
|
|
|
The ESR21 unit is a simple solar control.
|
|
The ESR21 unit is a differential control that can be used in many ways
|
|
|
|
The DL bus runs at 12 volts.
|
|
The data frame consist of 30 bytes (excluding sync and CRC).
|
|
The data are transmitted @ 488Hz, therefore the transmission of one data set takes about 0.67 seconds.

Setup

|
-----
|
|
|
|
.. note:: A new device task must be created for each value to be read from the DL bus!

Task settings
|
|
~~~~~~~~~~~~~
|
|
|
|
* **Device**: Heating - DL-Bus (Technische Alternative)
|
|
* **Name**: Name of the task (example name **ValueN**, where N is a number).
|
|
* **Enable**: Should the task be enabled or not
|
|
|
|
Sensor
|
|
^^^^^^
|
|
|
|
* **1st GPIO**: DL bus input e.g. **GPIO 14 (D5)**
|
|
* **DL-Bus Type**: **ESR21**
|
|
|
|
.. note:: The settings for **1st GPIO** and **DL-Bus Type** must be the same for all used DL bus tasks!
|
|
|
|
Inputs
|
|
^^^^^^
|
|
|
|
.. note:: The description of the **Frame data** and the related **Frame bytes** can be found in the section **Protocol**!

Data acquisition
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
* **Send to controller** 1..3: Check which controller (if any) you want to publish to. All or no controller can be used.
|
|
* **Interval**: How often should the task publish its value (10..60 seconds is normal).
|
|
|
|
.. note:: Intervall not less than **10 seconds**! The reading of the DL bus happens twice per intervall.
