Internal load controller
In this operating mode, the load controller inside the LMV5 is used (standard application).
The manipulated variable and the request for heat are internally generated and
handled.
Terminals X62 pin 1 and X62 pin 2 can be used to make an external changeover
between the internal setpoints W1 and W2.
