Coding for systems with domestic hot water heating is automatically recognized.
*2
These codings also apply on systems with one heating circuit without mixing valve and one heating circuit with mixing valve.
*3
Only on heating system types "000:002" and "000:003" (heating systems with one heating circuit with mixing valve).
