I’d love to. But I can’t. Vaillant does not make this configurable.
I also do not know my average daily turnover unfortunately.
My 190 liter tank (uniTOWER) is configured to 45ºC with 5º hysteresis. Based on your diagram, I think I’ll:
- change it to 48ºC and keep the 5º hysteresis — which should keep me in the dormant/slow growth parts
- disable the legionella run
It definitely is destroying efficiency. That’s crystal clear.
