In this menu, you can assign digital outputs to unit-related alarms and signals.
More specifically, you can determine the digital output for the common alarm

Using the "module status" parameter, you can adjust the digital output

In this menu, you can output analog measurement values via analog outputs so that
these can be recorded by a BMS, for example.
Choose one of 4 value outputs that are set as standard with the "Room temp." sensor
purpose.
This opens a window that allows you to apply settings for this value output. You can
activate the value output in the first line. This means that you can place the settings in
lines 2 to 4 beforehand and save them without the value output occurring. The value
output only begins once you set the parameter in the first line to "1". If there are several
sensors with the same purpose, an average value is calculated.
The actual value that is outputted is determined in line 2. Using purpose

The parameters in line 5 serve to calibrate the output. For example, if you have chosen
a sensor with the purpose Water temperature inlet 2 and have entered the value 5.0°C
