That would be awesome!
I'm on the same situation and need a function to control the pump. But unfortunately I've no clue how to do that because the heatpump itself controls the pump

I've created a PR #350 which adds ventilation option. It adds three additional entities: 1 Switch for ventilation activating, 1 Switch for selecting the HUP (heating circulation pump) and 1 number entity for changing the ventilation time (1...6 hours).

If you want to activate the ventilation, you have to switch in the following order:

• Number ventilation time (Hours)
• Switch ventilation HUP=ON
• Switch ventilation active=ON

Note:
The switches must be aktivated within several seconds otherwise the ventilation doesn't start.
