ebusd hwc mctype 9 unkown

[garageboxnv]

Using hassio mqtt integration gives me following error:

Ignoring invalid option received on topic 'ebusd/hwc/Mode', got '9', allowed: inactive, mixer, fixed, hwc, returnincr, pool, circulation

I have an vaillant aguaflow exclusive, I expect mode 9 might indicate that the mctype is a "buffercircuit"
