Reduced heating curve - not much diffeeence vailliant

Hi I reduced heating curve from 1.6 to 0.5 on my Vaillant vsmart. Not much difference - radiators still hot. Is something wrong ?

After ajdjustment my flow is 52 and return is 39. This sound ok?

 

From memory, adjusting the curve does not instantly change anything, it takes a few days to adapt. Could be wrong.

 

Ok. Just so you know I changed it all the way to 0.1!

Given I work from home and we are at home all of the day it works. It takes 2 hours to add a degree to tempreture but that’s fine with me. I like the fact you get radiators on for longer at a slightly lower tempreture rather then faster bursts.
