Hello Viessmann team.
I have a Vitocal 150-A AWO-E-AC 151.A16 heat pump and when the pump is supposed to shut down, it looks like it doesn't consider if there is currently an immediate request for hot water. The heat pump is switched off and after e.g. in 10 minutes it turns it on again, because there is the request for hot water that was entered even before the heat pump was turned off. It would be enough to check if this requirement is there before turning it off.
Thank you.
