Wds shows that without webasto pump is controlled from pin 9 blue 26pin connector from ihka. With webasto, wire goes only from webasto to the pump...
Or does it needed to be coded as aux heater to this work? (But even that really doesn't resolve what i'm after)
But even when I set ihka temp to 32c, pump isn't running, until I start webasto.
