Actual behavior

ebusctl read -f HwcMode states eco all the time, even when the system is actually set to balanced.

ebusctl find -w HwcMode
ERR: element not found

Used both the 'normal' website and 'next' for the config - no dice.

I can set curve, min flow temp, summer temp limit, but they all appear to be basv not hmu.

Expected behavior

HwcMode reads the correct mode and users are able to set the mode correctly.
