Weishaupt WPM (SG Ready) - Charger enabled: map: value not found: 9

[Jaybeste]

Describe the bug

EVCC throws an error "charger enabled: map: value not found: 9" when trying to connect to my Weishaupt heat pump. The heat pump is configured with the weishaupt-wpm template. It seems that the value 9 for the operating mode is not defined in the template.

Same happens for value 15, which is "Taktsperre" for my model WWP LS 10-B R. Will try to provide a pull request.

@Jaybeste When does your system go into state 9? I never saw that state. But from documentation, it reads like the heatpump can use electric heaters instead of the heatpump functionality or additionally to heatpump if not enough heating energy could be pumped. Is that correct?
